Mercury is normally considered to have 2 valence electrons- its configuration is 5d106s2. Mercury was long believed not to use any other electrons in forming bonds and is called a post transition element.
However the compound HgF4 was discovered in 2007. It can only be isolated by trapping at at very low temperatures (solid neon gas temperature) so in practical every day terms the 2 valence electron rule holds.

∙ 14y agoA neutral atom of mercury has 80 electrons. Because the number of protons and electrons are the same in a neutral atom, the number of electrons is equal to the atomic number, which is 80 for mercury. Of course, mercury ions have different numbers of electrons.

How many protons and electrons does mercury have?
Mercury (Hg) can ONLY have 80 protons, or else it cannot be mercury. The difference between its mass number (201) and 80 is 121, which is the number of neutrons. These can vary and are called isotopes. The number of protons can always only be 80 for mercury, tho.

Hg stands for mercury metal..only liquid state meta
Does Mercury have more protons than electrons than tin?
Yes. Tin (Sn on your periodic table) has an atomic number of 50, which means it has 50 protons and 50 electrons. Mercury (Hg) has an atomic number of 80, which gives it 30 more each of protons and electrons.
