Answer:

B

Explanation:

Because , it is the answer .

Based on the information provided in the chart, the statement that is best supported is Atom X will donate electrons to Atom Y. Option A is the correct answer.

Atom X has 6 valence electrons, which means it has 6 electrons in its outermost energy level. Atom Y has 2 valence electrons, indicating that it has 2 electrons in its outermost energy level. In a chemical reaction, atoms tend to either donate or accept electrons to achieve a stable electron configuration. Option A is the correct answer.

Atom X has more valence electrons than Atom Y, suggesting that it is more likely to donate electrons. Since Atom Y has fewer valence electrons, it is more likely to accept electrons from Atom X. Therefore, based on the number of valence electrons, Atom X will donate electrons to Atom Y in order to achieve a stable electron configuration.

A. An element.

As long as it's on the periodic table, it's always an element.

A compound is made up of two or more elements in a chemical reaction, resulting in covenant and/or ionic bonds.

A homogenous mixture (a solution) is a combination of two or more elements physically without causing a reaction (like salt water or applejuice).

Heterogeneous mixtures are physical combinations that mix but don't appear uniform (think of cereal in milk.)

Answer:

3 electrons comrade

Explanation:

Answer:

3 valence electrons

The element with the atomic number 113 would fall in the 13th column of the periodic table Group IIIA. This group has an electron configuration that would end as p1 , meaning there would be 3 valence electrons. The valence electrons are the electrons found in the highest energy level in the s and p orbital.

Explanation:

Nihonium has to be the #113 element of the periodic table

A. is the correct answer because Boron has 3 electrons too,

All elements in Group 13 have three electrons in their outermost energy level. The two most popular elements in this group are Boron and Aluminum.

Boron element would have properties most similar to the new element. Therefore, option (A) is correct.

The chemical properties of elements depend on the number of valence electrons in their valence shell. Elements in the same group in the modern periodic table have the same number of valence electrons. Therefore, chemical elements situated in same group of the modern periodic table have similar chemical behavior.

The chemical elements having an identical outer electronic configuration in their atoms are placed in the same group of the periodic table. These valence electrons of an element are responsible chemical behavior and reactivities of the elements.

Therefore, both Boron and a new element with atomic number 113  have three electrons in their valence shells. So they belong to the same group and will have similar chemical properties.

Answer:

Check explanation section.

Explanation:

In order to understand balanced force and unbalanced forces the first law of Newton should be considered as a basic knowledge.

For Balanced forces, there is equal equality in the direction of the forces. In balanced forces, there is no acceleration.

For unbalanced forces, there is acceleration that is go say there is going to be movement. Therefore, net force is equal to unbalanced forces.

(i) Suitcase dropped from a height.

Answer: since there is movement that is acceleration, then the force here is unbalanced force. The resultant force is downwards.towards the greater force direction.

(ii) A bicycle moving with constant velocity on a straight road.

Answer: As the bicycle moves at constant velocity on the straight road the force here is Balanced. Frictional forces balances the forces from the cyclist.

Answer:

Wind is the horizontal movement of air, transporting energy transferred from the earth's surface as sensible and latent heat. Sensible heat is transferred by the processes of conduction and convection. Conduction transfers energy within a substance, and convection transfers energy through the vertical movement of the heated substance. Latent heat is the transfer of energy by transforming the substance itself. As you recall, water has the ability to exist as liquid, gas or solid. The transformation from liquid to gas is called evaporation; the reverse process, from gas to liquid, is called condensation; from liquid to solid is known as solidification (freezing); and from solid to liquid, fusion (melting). Water can also be transformed directly from solid to gas (sublimation), or the reverse, through a process called deposition. We will see these various processes in the formation of clouds.

Answer:

A) Ionic bond

___transfer of electrons

B) Covalent bond

___sharing of electrons

C) Metallic bond

___freely moving electrons

The correct match of chemical bonds to its correct description are:

A) Ionic bond - transfer of electrons.

B) Covalent bond - sharing of electrons.

C) Metallic bond - freely moving electrons.

Chemical bonds are the attraction of electrons of different atoms to form a bond. These bonds are the reason for the joining of different atoms and forming of substances and compounds.

There are different types of bonds that are formed according to the different atoms and different types of attraction or joining. These bonds are ionic bonds, metallic bonds, and covalent bonds.

The covalent bonds are the strongest bonds because there is sharing of electrons in them. Ionic bonds transfer electrons to each other. Metallic bonds get the free-moving electrons of the elements.

Thus, the correct match is

A) Ionic bond - c, transfer of electrons.

B) Covalent bond - a, sharing of electrons.

C) Metallic bond - b, freely moving electrons.

b) Heating copper (ii) carbonate strongly - chemical change

c) Heating Zinc oxide strongly - chemical change

The given types of reaction indicates chemical changes. A chemical change is one in which a new kind of matter is formed. It is always accompanied by energy changes. The process is not easily reversible and hence, it is a permanent procedure.

 Burning of charcoal produces a new kind of produces in the combustion process.

Both heating of copper(ii)carbonate strongly and zinc oxide will lead to a decomposition reaction in which new compounds are formed.

The coefficient for iron (Fe) in the balanced chemical equation is 3.

Lets first analyse the chemical equation presented to us which is Fe + Cl2 = FeCl3

The number of iron atoms on each sides is 1. However, the number of Cl atoms on the left and right sides is 2 and 3, respectively.

To balance the equation, we need to make sure tht the same number of atoms of each element is present on both sides of the equation.

To balance the number of Cl atoms, we need to add a coefficient of 2 to FeCl3 which becomes Fe + Cl2 → 2FeCl3

For us to o balance the number of Fe atoms, we need to add a coefficient of 3 to Fe. It becomes 3Fe + Cl2 → 2FeCl3

The given electronic configuration is that of element rubidium which is a s-block element with one valence electron.

Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.

Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.

Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.
