Such atoms belong to a group in the periodic table of elements.
Outer electrons in metal atoms are loosely held and can easily move, allowing metals to conduct electricity and heat. In contrast, outer electrons in nonmetal atoms are tightly held, making nonmetals poor conductors of electricity and heat. Additionally, metal atoms typically have fewer outer electrons than nonmetal atoms.
Neutral atoms of neon have the same number of electrons as atoms of fluorine, magnesium, and sodium, excluding helium atoms.
The table was organized so that elements of similar properties are in the same group. What (partly) determines reactivity is the number of electrons an atom has in it's ground state. .

No. Argon has eight electrons in its outer shell and magnesium has two electrons in its outer shell.
Elements whose atoms have the same number of outer electrons have similar properties..
Elements whose atoms have the same number of outer electrons have similar properties..
Such atoms belong to a group in the periodic table of elements.
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.
Atoms of the elements in a group have the same number of electrons in their outer energy shells. This gives the elements similar Chemical Propetries.
Outer electrons in metal atoms are loosely held and can easily move, allowing metals to conduct electricity and heat. In contrast, outer electrons in nonmetal atoms are tightly held, making nonmetals poor conductors of electricity and heat. Additionally, metal atoms typically have fewer outer electrons than nonmetal atoms.
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.
The valence band of an atom is composed of an s orbital and up to three p orbitals, each of which can contain at most two electrons. Atoms try to either completely fill or completely empty these orbitals when they undergo chemical reactions and usually do so by transferring the minimum number of electrons possible. Hydrogen and helium are a special case as they can have no p orbitals.
Neutral atoms of neon have the same number of electrons as atoms of fluorine, magnesium, and sodium, excluding helium atoms.

The number of outer electrons is the same as the group number.
