2
atoms in a group have the same number of valence electrons
16
Such atoms belong to a group in the periodic table of elements.
A Group 6A element gains two electrons A Group 2A element loses two electrons A Group 3A element loses three electrons A Group 3A element loses three electrons group 1a element loses one electron group 7a gains one electron
all the members of 3rd A group of periodic table have 3 electrons in outermost shell they are B ,Al, Ga, Tl and In.
A neutral atom of silicon will have 4 valence electrons. The amount of valence electrons that a neutral atom will have can be found by the atoms group number in the periodic table.
Atoms in the same group (in the same vertical column) of the periodic table have the same number of electrons in their outer shell. A neutral atom has the same number of electrons as it has protons. The number of protons is given by it's atomic number. The electrons are considered to be arranged in "shells." The outermost shell can have from 1 to 8 electrons. The effect of being in the same group is that the atoms within a group have similar reactions.

number of valence electrons
The alkaline earth group has two valence electrons.
Chlorine is in Group 17 of the Periodic Table.
A neutral sulfur atom has 6 valence electrons. Sulfur is in group 16 of the periodic table, so it has 6 valence electrons in its outermost shell.
No. there are no unpaired electrons in xenon. In neutral form, xenon will have 8 valence electrons.
A neutral group of atoms held together by a covalent bond is called a molecule. In a covalent bond, atoms share electrons to achieve a stable configuration. This sharing of electrons creates a strong bond between the atoms in the molecule.
Atoms try to imitate the noble gases in the periodic table by changing their electrons. Noble gases have stable electron configurations, so other atoms will gain, lose, or share electrons in order to achieve a similar stable configuration like the noble gases.
The number of separate electrons for group 2 metal atoms is twice the number of atoms. This is because each group 2 metal atom typically loses two electrons to achieve a stable electron configuration.
The periodic table also has a special name for its vertical columns. Each column is called a group. The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons.
