How can valence electrons be determined

WebThe first shell (of all atoms) has 1 subshell of s-orbitals containing 1 s orbital. This means that the first shell can hold 2 electrons. The second shell has 2 subshells: 1 s-orbital and 3 p-orbitals. This means that the second shell can hold 8 total electrons. Every orbital is a shape (that can be determined by a trigonometric function I ... The number of valence electrons of an element can be determined by the periodic table group (vertical column) in which the element is categorized.
