Question

Use Lewis symbols to show electron transfer between the given atoms to form cations and anions: Ca and O

Answer 1

To use Lewis symbols to show electron transfer between the given atoms to form cations and anions in Ca and O- The electronic configurations of Ca and O are as given below:

Ca has 2, 8, 8, 2

O has 2, 6

So,Oxygen requires two electrons more to complete its octet, whereas the calcium has two electrons more than the nearest noble gas

(a) K and S:

The electronic configurations of K and S are as follows:

K: 2, 8, 8, 1

S: 2, 8, 6

Sulphur (S) requires 2 more electrons to complete its octet. Potassium (K) requires one electron more than the nearest noble gas i.e., Argon. Hence, the electron transfer can be shown as:

(b) Ca and O:

The electronic configurations of Ca and O are as follows:

Ca: 2, 8, 8, 2

O: 2, 6

Oxygen requires two electrons more to complete its octet, whereas calcium has two electrons more than the nearest noble gas i.e., Argon. Hence, the electron transfer takes place as:

(c) Al and N:

The electronic configurations of Al and N are as follows:

Al: 2, 8, 3

N: 2, 5

Nitrogen is three electrons short of the nearest noble gas (Neon), whereas aluminium has three electrons more than Neon. Hence, the electron transference can be shown as:
