how to figure out valence electrons for transition metals?

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.

Aluminium has 3 valence electrons. Valence electrons are located in the outermost shell of an element.

The six electrons in the outermost shell allow selenium to have a variety of valence numbers. Selenium compounds have been found that have valences of -2, 4, and 6.

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. For example.

Apply the rule of the periodic table to your element. The rule is as follows: If an element is not a transition metal, then valence electrons increase in number as you count groups left to right, along a period. Each new period begins with one valence electron.

The Lewis structure for CO has 10 valence electrons. For the CO Lewis structure you'll need a triple bond between the Carbon and Oxygen atoms in order to satisfy the octets of each atom while still using the 10 valence electrons available for the CO molecule.

Now, magnesium, Mg , has 2 valence electrons. In order to complete its octet, it must get to 8 valence electrons. The only way for magnesium to accomplish this is to give up its two valence electrons and have one of its filled energy levels become the valence shell, i.e. the outermost energy level.
