Question

consider the element carbon. how many electrons can be found in a carbon atom? how many are valence electrons? a 6,2 b 6,4 c 12,4 d 12,6

Explanation:

Step1: Identify atomic number and electron - shell rules

The atomic number of carbon (C) is 6. The first electron - shell can hold 2 electrons and the second can hold 8.

Step2: Determine total electrons and valence electrons

The number of electrons in a neutral carbon atom is equal to its atomic number, which is 6. The electron configuration is 2 in the first shell and 4 in the second shell. Valence electrons are the electrons in the outermost shell, so carbon has 4 valence electrons.

Answer:

B. 6, 4
