The group numbers tell the number of valence electrons. Without looking on the group number you can also tell the number of valence electrons by looking at the highest energy level in the electronic configuration.

How do you determine the number of valence electrons in an element?
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.
How do you calculate the number of valence electrons in an atom?
To calculate the number of valence electrons in an atom, you look at the group number of the element on the periodic table. The group number tells you how many valence electrons the atom has. For example, elements in group 1 have 1 valence electron, elements in group 2 have 2 valence electrons, and so on.

Are periods valence electrons or electron shell?
The period tells you the valence ELECTRON SHELL (energy level). The group tells you the number of valence electrons.
What does the group number of A elements (in the AB numbering system) tell about valence electrons?
The group number of A elements in the AB numbering system tells you the number of valence electrons that element has. Elements in the same group have the same number of valence electrons, which determines their chemical properties.
What does the group number of A elements (in the AB numbering system ) tell about valence electrons?
The group number tells you the number of valence electrons present.

How can you use a periodic table to predict the number of valence electrons an element has without having to draw the Bohr diagram?
In general, except for the transition elements, the group number will tell you the number of valence electrons. For example, Na is in group 1 and has 1 valence electron. Cl is in group 7 and has 7 valence electrons.
What does the number of valence electrons tell you about a given element?
If its positive it tells u that it has that number of valence electrons. If negative it tells you that it requires that number of electrons to make the valence electrons filled up/stable. If you know which Ion it is, you know the number of valence electrons of the neutral Atom. It corresponds to the group in the periodic table, the element is in. For example: Mg. It's in group 2, so it has 2 valence electrons. The oxidation number now tells you how many more or less electrons the atom has. For example: Mg(II) has 2 positive charges, hence two electrons less. That means it has 0 valence electrons. Take complete number of valence electrons, subtract the oxidation number and you get the number of valence electrons in the ion.
