Почему у Ванадия на последнем уровне 2 электрона, если кол-во электронов на последнем уровне = номеру группы, но Ванадий в 5 группе?

Ответы

Автор ответа: karikrut

Ванадий находится в побочной подгруппе, а в них сначала заполняется

s-орбиталь, на которой максимум 2 электрона, а потом d-орбиталь

То есть, в Ванадие заполнена 4s-орбиталь, и заполняется 3d
