Answer:
A. Silicon
Step-by-step explanation:
The ability of an atom to attract electrons is known as electronegativity.
Electronegativity is the measure of the relative tendency with which the atoms of the element attract valence electrons in a chemical bond.
- Across a period from left to right, the ability to attract electrons increases.
- Down a group, the ability decreases.
- Silicon is to the left most part and it will have the the least ability to attract electrons.
