The halogen elements have seven valence electrons in their outermost electron shell. Number of valence electrons = main group number (neutral atoms) the main group number of an element can be found in its periodic table column.
Which Element Has 7 Valence Electrons. Halogens have 7 valence electrons. Calcium is a group 2 element with two valence electrons. The valence electrons of an element can be found out by closely examining the vertical column in which the elements are grouped in. Alkali metals have one valence electron.

Which group contains elements with two valence electrons? Calcium is a group 2 element with two valence electrons. Alkali metals have eight valence electrons. The valence electron has to be determined by following a few steps.
119 rows elements valence electrons;
Fluorine has atomic number 9. Nitrogen has five valence electrons. The electron configuration is one of them. Fluorine has 7 valence electrons. Therefore, when these elements can receive an electron from another atom, they form very stable compounds since their outermost shell is full. Number of valence electrons = main group number (neutral atoms) the main group number of an element can be found in its periodic table column.
