Question

A calcium ion has a charge of +2. How many protons and electrons does it have?

An atom has 6 protons, 7 neutrons, and 6 electrons.
Fill in the blanks below for this atom:
Atomic number_____
Atomic mass_______
Charge_______
This atom belongs to which element?

Answer 1

The calcium ion is a cation (positive charge) and it has 20 positive protons and 22 valence electrons since it gains two from the reactions...
The atom with 6 protons, 7 neutrons and 6 electrons is the element Carbon.
Atomic Number : 6
Atomic Mass : 12
Charge : Overall neutral charge because the same amount of positive subatomic particles negates the charges of the negative subatomic particles. Hope This Helps!! (>ω<)
