the cadmium atom looses two electrons and its radius decreases because by taking away two electrons (negatively charged) it makes the nucleus positive with a positive 2 charge. since theres two less electrons the radius is smaller. hope i helped :D
The neutral atom of cadmium has 48 electrons.
Cadmium sulfide (CdS) has two atoms.
Cadmium is the only neutral atom (not electrically charged) to have 48 electrons.
Cadmium has an atomic number of 48, therefore it has 48 protons in the nucleus and 48 electrons in the neutral atom. There are a number of isotopes (list from wikipedia article Cadmium) 106Cd 58 neutrons 108Cd 60 neutrons 111Cd 63 neutrons 112Cd 64 neutrons 113Cd 65 neutrons 114Cd 66 neutrons 116Cd 68 neutrons
When an atom gains electrons, it becomes negatively charged because it now has more electrons than protons. When an atom loses electrons, it becomes positively charged because it now has more protons than electrons.
The neutral atom of cadmium has 48 electrons.
Cadmium sulfide (CdS) has two atoms.
The atom becomes a negative ion.
When an atom becomes ionized, it gains or loses electrons (usually one).
When the number of electrons changes, the atom becomes an ion. An atom becomes a positively charged ion (cation) when it loses electrons and a negatively charged ion (anion) when it gains electrons.
One atom of Cadmium makes one molecule of Cadmium.
When an atom loses or gains electrons, it becomes an ion.
Cadmium is the only neutral atom (not electrically charged) to have 48 electrons.
The radius of a cadmium atom is smaller than the radium of a mercury atom. The trend for atomic radius is that the radius becomes larger toward the left side of the row and toward the bottom of the group.

When an atom gains electrons, it becomes negatively charged because it now has more electrons than protons. When an atom loses electrons, it becomes positively charged because it now has more protons than electrons.
When the number of protons in an atom changes, the identity of the element changes because the number of protons determines the element's atomic number. If the number of protons changes, the atom becomes a different element. This process is called nuclear fusion or fission.
