A) 1021Ne{ }_{10}^{21} \mathrm{Ne}1021Ne
B) 1020Ne{ }_{10}^{20} \mathrm{Ne}1020Ne
C) 2010Ca{ }_{20}^{10} \mathrm{Ca}2010Ca

Isotope

An isotope is a variant of a particular chemical element, which differs in neutron number, while retaining the same number of protons.

Neutrons

Subatomic particles found in the nucleus of an atom, having no electrical charge and a mass slightly greater than that of a proton.

Element

A pure chemical substance consisting of one type of atom, distinguished by its atomic number, which is the number of protons in its nucleus.

  • Absorb the details of atomic composition, particularly protons, neutrons, and electrons.
  • Become acquainted with the symbols and atomic numbers of standard elements.
  • Familiarize oneself with the connection between atomic number (Z), mass number, and the nature of isotopes.
