2040Ca{ }_{20}^{40} \mathrm{Ca}2040Ca contains how many neutrons?
A) 20
B) 40
C) 60
D) None of the above.
Ca
The chemical symbol for calcium, an element with atomic number 20, essential for living organisms, particularly in cell physiology and bone formation.
Neutrons
Electrically neutral subatomic particles found in the nucleus of an atom, contributing to the atom's mass but not its charge.
Isotope
Variants of a particular chemical element which differ in neutron number, and subsequently in mass, but share the same number of protons.
- Characterize isotopes and their relevance based on the quantity of neutrons.
- Calculate the constituent numbers of protons, neutrons, and electrons in atoms or isotopes.
- Discriminate between isotopes by examining their mass numbers and neutron counts.
