Answer:
The correct option (c) "is held together by ionic bonds".
Step-by-step explanation:
Table salt is NaCl. It is a combination of Sodium and Chlorine.
There is 1 valance electron in sodium. Its electronic configuration is 2,8,1
The electronic configuration of Chlorine is 2,8,7. It means that it needs 1 electron so that its octet gets completed.
Na transfers one electron to Cl. It becomes Na⁺. Cl gains one electron From Na. It becomes Cl⁻.
As a resuslt, Na⁺ and Cl⁻ forms. Both Na and Cl are ions. They held together by ionic bonds.

B IS ANSWER
Answer:
x ≤ 1
Step-by-step explanation:
First, add 5 to both sides (we want to isolate x).
3x ≤ 3
Now, we divide by 3.
x ≤ 1
That's the answer! All values equal to or less than 1 are solutions of 3x - 5 ≤ -2.
Hope this helps
