Answer:
[Ne] 3s2 3p2
Explanation:
Neon (Ne) is the noble gas right before silicon (Si).
Then right after neon is the 3s subshell. It has two electrons and is full.
After 3s comes the 3p subshell, and silicon only has two electrons in the 3p subshell (you can just count the electrons in each subshell on your periodic table).
Answer: A more electronegative atom will have more attraction to the electrons in a chemical bond.
Explanation:
An atom that is able to attract electrons or shared pair of electrons more towards itself is called an electronegative atom.
For example, fluorine is the most electronegative atom.
Due to its high electronegativity it is able to attract an electropositive atom like H towards itself. As a result, both fluorine and hydrogen will acquire stability by sharing of electrons.
Thus, we can conclude that a more electronegative atom will have more attraction to the electrons in a chemical bond.
