Question

atoms decay into smaller atoms particles. each alpha particle has, and 0 electrons. the table ral neutral, low - mass atoms. an alpha particle is also referred to as a nucleus of which isotope? lithium - 7 helium - 4 hydrogen - 2 helium - 2 s of low - mass elements symbol atomic number number of neutrons 1 0 2 2 3 4 4 5

Explanation:

An alpha - particle consists of 2 protons and 2 neutrons. The atomic number of helium is 2, and helium - 4 has 2 protons and 2 neutrons. So, an alpha - particle is equivalent to a helium - 4 nucleus.
