Question

Based on the electron configuration of the two atoms, predict the ratio of metal cationic (+) atom to nonmetal anionic (-) atom in the compound.
Lithium 1s^22s^1
Chlorine 1s^22s^22p^6 3s^23p^5
​

Answer 1

Answer:

Option A. 1:1

Explanation:

From the question given above, the following data were obtained:

Li => 1s² 2s¹

Cl => 1s² 2s²2p⁶ 3s²2p⁵

Lithium (Li) will form compound with Cl by losing 1 electron as shown below:

Li —> Li⁺ + e¯ ..... (1)

Cl on the other hand will accept 1 electron from Li to form the chloride ion, Cl¯ as shown below:

Cl + e¯ —> Cl¯ ...... (2)

Combining equation 1 and 2, we have:

Li + Cl + e¯ —> Li⁺ + Cl¯ +

Cancel e¯ from both side

Li + Cl —> Li⁺Cl¯

Thus, the ratio of metallic cation (+) to non-metallic anion (-) in the compound is 1:1
