Magnesium, Mg, atom number 12, 12 protons and 12 electrons.
If it is neutral element, then the element will be magnesium.
magnesium
Magnesium
A neutral atom has the same number of electrons as it does protons. The atomic numbers on the periodic table for each element are the number of protons. So, look up the element on the periodic table, note its atomic number, and you will then know the number of protons and electrons in a neutral atom of that element. For example, magnesium (Mg) has atomic number 12. So a neutral Mg atom would have 12 protons and 12 electrons.
halogens
Metals give electrons.
yes, the number of dots represent the number of valence electrons in the periodic table.
Transition metals are located in group 3-12 of the periodic table. The middle of the periodic table.

Its by electrons.
Periodic table lists the elements in the increasing order of atomic number. Atomic number = Number of protons = Number of electrons
Atoms that tend to gain electrons are located on the far left side of the periodic table.
Calcium has 20 electrons
Magnesium is element 12 and belongs to Group 2 of the Periodic Table, are the outermost electrons, magnesium has two valence electrons.
period 3 elements in the periodic table have 3 electrons in there outher shell hence the name.
all the members of 3rd A group of periodic table have 3 electrons in outermost shell they are B ,Al, Ga, Tl and In.
The transition metals are located in groups 3 - 12 on the Periodic Table.
8 electrons.
