The answer is letter C.
Ions are formed when atoms lose or gain electrons in order to fulfill the octet
rule and have full outer valence electron shells.

A carbon atom has six protons. This means that a carbon atom also has
a) Six electrons
b) Six neutronsFurther explanation
The Atomic Number (Z) indicates the number of protons in an atom of an element. If the atom is neutral then the number of protons will be equal to the number of electrons. So the atomic number can also indicate the number of electrons.
So atomic number = number of protons = number of electrons
Mass Number (A) is the sum of protons and neutrons
Mass Number (A) = Number of protons Number of Neutrons
So that the relationship between atomic numbers and mass numbers can be formulated as follows:
Atomic Number (Z) = Mass Number (A) - Number of Neutrons
In the following element notation,
X = symbol of elemental atom
A = mass number
= number of protons number of neutrons
Z = atomic number
= number of protons = number of electrons, on neutral elements
Determination of electron configurations based on principles:1. Aufbau: Electrons occupy orbitals of the lowest energy level 2 Hund: electrons fill orbitals with the same energy level 3. Pauli: no electrons have the same 4 quantum numbers
Carbon (C) is a non-metallic element in group 4A and has an atomic number of 6 and a mass number of 12 u
1s² 2s² 2p² or can be written down
[He] 2s² 2p²
Since the atomic number shows the number of protons = the number of electrons (in a neutral atom), the number of protons and electrons of a Carbon atom is = 6
While the number of neutrons:
Mass Number (A) = Number of protons+Number of Neutrons
12 = 6 +Number of Neutrons
Number of Neutrons = 12 - 6
Number of Neutrons = 6
a) Six electrons
b) Six neutrons
Both answers are correct because carbon atoms have 6 protons and 6 electrons
c) More protons than electrons
the number of protons can exceed or be greater than the number of electrons if the atom releases its electron, but on a neutral atom like this carbon atom, the number of protons = the number of electrons
d) An atomic mass that equals six
an atomic mass of carbon atom = 12, so this answer is wrongLearn more
