Ответ:
Number of Protons = 20
Number of Electrons = 20
Number of Neutrons = 23
Explanation:
Number of Protons:
As the number of protons present in the nucleus are equal to the atomic number therefore, using periodic table one can easily find out the atomic number of Ca atom. Hence, Ca is present in group 2 and period 4 and having an atomic number of 20. Therefore, number of protons in Ca atom are 20.
Number of Electrons:
As shown in statement, Ca is not carrying any type of charge. It means this atom is neutral in nature. Which means, it is carrying the same number of electrons as the number of protons in order to give a neutral atom. Therefore, it contains 20 electrons.
Number of Neutrons:
Number of neutrons can be calculated using following formula,
No. of Neutrons = Atomic Mass - Number of Protons
As,
Atomic Mass = 43
So,
No. of Neutrons = 43 - 20
No. of Neutrons = 23
