Ap sublevel has 3 electrons. How should they be arranged

Chemistry

Answer:

C.)One electron in each p orbital

Explanation:

In a P-sublevel with 3 electrons, they should be arranged with one electron going into each p-orbitals.

This is in accordance with the Hund's rule of maximum multiplicity.

The rule states that "electrons go into degenerate orbitals or sub-levels(p,d and f) singly before paring up".

Since the p-orbital is 3-fold degenerate with a capacity to accommodate a maximum number of 6 electrons, given 3 electrons, they will follow the Hund's rule in order to fill the orbitals.

So one electron will go in each p - orbitals easily.

What is the mass ratio and atomic ratio for cl2o7

elixir [45]

Answer:

Mass ratio: 71:112

Atomic ratio: 2:7

Explanation:

1. To get the mass ratio of of the compound Cl2O7, the following steps are followed:

- The atomic mass of Cl = 35.5g/mol, O = 16g/mol

- The mass of each element in the compound is as follows:

Cl2 = 35.5(2) = 71g

O7 = 16(7) = 112g

The mass ratio is the ratio of one mass of an element to another in the compound, hence, the mass ratio is 71:112

- The molar mass of the compound, Cl2O7, is determined:

71 + 112 = 183g/mol

- The mass percent of each element is determined by dividing the mass of each element present by the Molar Mass:

Cl = 71/183 = 0.3879 × 100 = 38.8%

O = 112/183 = 0.612 × 100 = 61.2%

2. Atomic ratio is the ratio of one atom in a molecule to another. It can be calculated this:

In Cl2O7, there are 9 total atoms (2 atoms of Cl + 7 atoms of oxygen).

Hence, that atomic ratio of Cl to oxygen in Cl2O7 is 2:7

An ionic bond occurs between what particles?

atroni [7]

Answer:

A positive and negative ion.

Explanation:

Ionic bond:

It is the bond which is formed by the transfer of electron from one atom to the atom of another element.

Both bonded atoms have very large electronegativity difference.

The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.

For example:

Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion. Sodium have one valance electron while chlorine have 7 valance electrons. In order to complete the octet chlorine require one electron while sodium need to lose its one electrons. That's why when both atom combine sodium lose its electron and becomes positive ion i.e cation while chlorine accept its electron and becomes negative ion called anion and bond between them is ionic bond.
