Any element in the 2nd column of the Periodic Table, for example calcium. A good periodic table to use to answer questions like this is...

Helium has 2 electrons (total of 2 electrons and 2 valence electrons)
You can determine how many valence electrons an atom has by what family the element of the atom is in. For instance, if the element is in family 8A, the number of valence electrons will be 8. Or, if the element is in family 2A, the number of valence electrons for the atom will be 2. So, whatever number family the atom is in, the number of valence electrons equals that.
To find the valence of an element on the periodic table, look at the group number. Elements in group 1 have 1 valence electron, group 2 have 2 valence electrons, and so on. For transition metals, the valence can vary so it's determined by the charges in their compounds.
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.
To determine the number of valence electrons for an element on the periodic table, you look at the group number of the element. The group number tells you how many valence electrons the element has. For example, elements in group 1 have 1 valence electron, elements in group 2 have 2 valence electrons, and so on.

To determine the number of valence electrons in an element, you look at the group number on the periodic table. The group number tells you how many valence electrons an element has. For example, elements in group 1 have 1 valence electron, elements in group 2 have 2 valence electrons, and so on.
The valence of an element in a chemical compound can be determined by looking at the group number of the element on the periodic table. The group number indicates the number of valence electrons an element has. For example, elements in group 1 have a valence of 1, elements in group 2 have a valence of 2, and so on. The valence of an element is important in understanding how it will react with other elements to form compounds.
