Helium has 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.
Carbon is a typical tetravalent chemical element.
Calcium is a non metal element. There are 20 electrons in a single atom.
In a Lewis structure, the valence electrons of an atom are represented as dots. Valence electrons are the electrons in the outermost energy level of an atom and are involved in chemical bonding. These electrons are important in determining the chemical properties of an element.

It depends on the atom. List what element the atom is from.

3 valence electrons
Valence electrons are the electrons in the outermost energy level of an atom. They are involved in chemical bonding and determine the reactivity of an element. The number of valence electrons influences the element's properties and behavior in chemical reactions.
The electrons in the valence band, this can be 1 to 8 electrons (in the s and p orbitals of the outer shell) depending on the element.
Valence electrons are the outermost electrons in an atom that participate in chemical bonding. They are found in the highest energy level (shell) of an atom. The number of valence electrons can determine an element's reactivity and the types of chemical bonds it can form.
The valence electrons are the outer most electrons and the principal energy level in which they belong will vary for element to element and generally corresponds to the period number in which the element is present
Calcium is a non metal element. There are 20 electrons in a single atom.
The number of valence electrons depends on the element and it could have 1 to 8 valence electrons.
The same number of valence electrons as xenon.
