an uncharged carbon atom has select total electrons, and select electrons in its valence shell.

Explanation:

Magnesium has an atomic number of 12. Its electron - configuration is 2, 8, 2. To achieve a stable octet configuration, it loses 2 electrons. Losing electrons results in a positive charge. So, a stable magnesium ion has a charge of + 2. For carbon, its atomic number is 6, so an uncharged carbon atom has 6 total electrons. The electron - configuration of carbon is 2, 4, so it has 4 electrons in its valence shell.

Answer:

Question 1: B. +2
Question 2: 6, 4
