The ability of an atom to loss this number of electrons.
Valence electrons and group number for metal are same. For non-metals, valence electrons are equal to group number-10.
Metalloids typically have 3 to 6 valence electrons. This intermediate number of valence electrons allows metalloids to exhibit both metal and non-metal characteristics.
2 is the standard number of valence electrons
Calcium is a metal that has two valence electrons.
Far from it. Aluminum has 3 valence electrons. The highest number is 8, which the noble gases other than helium have (helium has only 2). Metals can have 1, 2, or 3 valence electrons, so aluminum has the greatest number that an element can have if it is a metal. Once you get to 4 valence electrons (which the element carbon has) you are in the nonmetal range.

Calcium is a metal that has two valence electrons.
N and V have same number of valence electrons.The number of valence electrons is 5. V is a metal while N is a non metal.

All alkali earth metals have 2 valence electrons.
E. It is metal. Calcium has 2 valence electrons and is classified as a metal. It is also reactive, especially with water and oxygen.
Beryllium is the alkaline earth metal that has 2 valence electrons.
Magnesium and beryllium both have two valence electrons, as they are in Group 2 of the periodic table. Any element in the same group will have the same number of valence electrons. Therefore, any other alkaline earth metal, such as calcium (Ca), also has two valence electrons.
There is one valence electron in lithium, also in every other alkali metal element.
Nonmetals attract electrons.
