Answer:
Ar < Cl - < S2-
Explanation:
All the species written above are isoelectronic. This means that they all possess the same number of electrons. All the species above possess 18 electrons, the noble gas electron configuration.
However, for isoelectronic species, the greater the atomic number of the specie, the smaller it is. This is because, greater atomic number implies that their are more protons in the nucleus exerting a greater attractive force on the electrons thereby making the specie smaller in size due to high electrostatic attraction.
Answer:
lymphocytes
Explanation:
it consists of the b and the t cells
Answer:
They are atoms that make up a subatomic particle
Explanation:
Atoms are made up of protons, neutrons and electrons, also known as subatomic particles. Because an atom is neutral, the number of electrons is equal to the number of protons. Electrons circle the nucleus, which is made up of protons and neutrons.
