how many valence electrons do the transition elements have?

2 Answers. Most transition metals have 2 valence electrons. Valence electrons are the sum total of all the electrons in the highest energy level (principal quantum number n). Most transition metals have an electron configuration that is ns2(n−1)d , so those ns2 electrons are the valence electrons.

In general, the number of valence electrons is the same within a column and increases from left to right within a row. Group 1 elements have just one valence electron and group 18 elements have eight, except for helium, which has only two electrons total.

The transition metals are able to put up to 32 electrons in their second-to-last shell. Something like gold (Au), with an atomic number of 79, has an organization of 2-8-18-32-18-1. Of course, there are still some rules. No shell can have more than 32 electrons.

How many valence electrons does oxygen (O) have? A: Any element in group 1 has just one valence electron. Examples include hydrogen (H), lithium (Li), and sodium (Na). Any element in group 18 has eight valence electrons (except for helium, which has a total of just two electrons).

Transition Metals So the valence electrons for a transition metal are the ns and (n-1)d electrons. This means that manganese (Mn) has the electron configuration [Ar]4s²3d⁵ and 7 valence electrons.

The transition elements are unique in that they can have an incomplete inner subshell allowing valence electrons in a shell other than the outer shell. Other elements only have valence electrons in their outer shell. This allows transition metals to form several different oxidation states.

Sodium has one valence electron. The element has a full innermost electron shell of two electrons and a full shell of eight electrons in the next shell. The third shell, which is the outermost and the valence shell, has only one electron. Valence electrons influence chemical reactivity.
