Answer:

B-29

Explanation:

Since there are 29 positive charges in the nucleus, there must be 29 negative charges. And cause the atomic number of copper is 29.

Answer:

This question is incomplete

Explanation:

This question is "lacking" in some words. A substance that conducts electric current when in it's liquid state is an electrovalent or ionic compound and the type of bond present in this substance is electrovalent or ionic bond. This is the type of bond that involves the transfer of electron(s) between constituent atoms. One major characteristic of these substances is that they conduct electric current when dissolved in water. Examples include NaCl and KBr

Explanation: edge 2020 chem

Answer:

Each of the four blocks of the periodic table is the collection of elements that have common valence orbitals, or that their valence are found in one of the four orbitals with azimuthal quantum number 0, 1, 2, or 3 which corresponds to the shape (s), principal (p), diffuse (d), or fundamental (f) orbitals respectively

The maximum number of electrons in the s-orbital = 2 electrons

The maximum number of electrons in the p-orbital = 6 electrons

The maximum number of electrons in the d-block = 10 electrons

The maximum number of electrons in the f-orbital = 14 electrons

Therefore, given that the elements of the within each of the blocks have their valence electron in the corresponding orbital in which they are located on the periodic table, given the periodic nature of the periodic table, the width of each block of elements corresponds to the maximum number of elements that can be found in their valence orbital.

Therefore, we have;

The width of the s-block elements = 2 block units

The width of the p-block elements = 6 block units

The width of the d-block elements = 10 block units

The width of the f-block elements = 14 block units

Explanation:

Answer:

13

Explanation:

The mass number of an atom is the sum of the number of protons and neutrons.

27 = protons + 14

protons = 13

The number of protons is equal to the atomic number.

Answer: 41 or Niobium

Explanation: To get the number of Protons or Electrons given the number of Neutrons and Mass, you have to add the given numbers. This gives the number of Protons and Electrons which is the same number as the Atomic number. So, 14 Neutrons plus the mass of 27 is equal to 41, which gives the element Niobium

Answer:

1.  c

2. ionic

3. c

4. ionic

5. alloy or ionic

Explanation:

The compound classification.

The compounds are classified as per several different criteria and one common elements is the specific element that is present this makes it an iconic or a molecular. The presence of the oxides, hydrides, and various atomic groups.

Hence the answer is melting point to conductivity classified as c, iconic, c, iconic, and alloy.

Answer:

The answer is 1:2 option B

Plz mark as brainliest............. hope it helps

The ratio of the metal cationic atom to the nonmetal anionic atom will be 1 :2. Therefore, option B is correct.

A lewis electron dot representation is utilized to represent the number of bonds, the bonding atoms, and the lone pairs on the atoms in the molecule or chemical compound.

Straight lines are used to represent the bond between atoms that are bonded to one another and excess electrons are represented as dot pairs to show the lone pairs on the atoms.

In the given image, calcium has two valence electrons and Fluorine needs one electron to complete its octet. So the calcium will donate its two electrons to two F. Each Flourine will accept one electron Therefore, the compound formed will be CaF₂.

Therefore, the ratio of the calcium cationic atom to the Fluorine anionic atom will be 1 : 2.

#SPJ2

Answer:

33.33 Watt

Explanation:

we know that P= W/t

W= work

t= time (in seconds)

so here

W= 100,000J

and t= 50 min= 50×60 sec= 3000 s

so P= 100,000/ 3000

=100/3 = 33.33Watt

Answer:

In a row from left to right the atomic radius decreases.

Answer:

Cobalt

Explanation:

The number of protons in an atom is called the atomic number.

Atomic number of an element is used by chemists to determine the element. The periodic table for example is based on the atomic number of elements.

Since both given elements have a proton number of 27, they are both the same element.

We simply check the periodic table for the element whose atomic number corresponds to this.

  The element here is Cobalt.

What differs between the two of them is that they are different isotopes.

Explanation:

When a substance is heated, it gains thermal energy. Therefore, its particles move faster and its temperature rises. When a substance is cooled, it loses thermal energy, which causes its particles to move more slowly and its temperature to drop.

When the temperature of a substance is increased, i.e., if you double the Kelvin temperature of a substance, you double the average kinetic energy of its molecules. When the average kinetic energy of the molecules goes up (a rise in temperature), the average speed of the molecules increases.

Answer:

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L} \\[/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

[tex]n = \frac{6.4 \times {10}^{22} }{6.02 \times {10}^{23} } \\ = 0.10631229...[/tex]

We have the final answer as
