labwork [276]3 years ago
6 0

Ans: A)

The electron configuration of an element can be represented based on Aufbau principle according to which the electrons fill up from the lower to higher energy levels.

s orbitals can accommodate a maximum of 2 electrons

p orbitals = 6 e-

d orbitals = 10 e-

f orbitals = 14 e-

The atomic number for sodium (Na) = 11

The 11 electrons in Na can be arranged as follows:

Na[11] = 1s²2s²2p⁶3s¹

The octet rule states that the formula for a compound is derived by Group of answer choices having a net charge of magnitude 8.
balandron [24]

Answer:

Atoms bonds with 8 electrons

Explanation:

Octet rule is a chemical rule that shows elements in main group bond so that each atom have 8 valence electrons in the outmost shell which make them to have similar electronic configuration with Noble gases This is important because the sharing of electrons make atoms to have full shell. Atoms with electrons not up to 8 react with more stable compound.
