8 electrons
5 valence electrons.
Oxygen atoms have 6 electrons in the highest occupied energy level. They are two 2s electrons and four 2p electrons. All elements in Group 16 have 6 valence electrons. For Groups 13-18, subtract 10 from the group number and that gives you the number of valence electrons (the electrons in the highest energy s and p orbitals). The Group 1 elements have one valence electron and the Group 2 elements have two valence electrons. The transition metals can vary in the number of valence electrons. You can't necessarily go by group number for them.
Because it has it has eight electrons in the outermost occupied energy level.
It would be 3 electrons!Why?Antimony: 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p3 Nitrogen: 1s2,,2s2,2p3Phosphorus: 1s2 2s2 2p6 3s2 3p3Arsenic: 3d10 4s2 4p3Bismuth: 4f14 5d10 6s2 6p3so on..
The group numbers tell the number of valence electrons. Without looking on the group number you can also tell the number of valence electrons by looking at the highest energy level in the electronic configuration.
5 valence electrons.
2. the number of electrons on the outermost level is always equal to the group number. Barium is group 2 therefore it's outermost energy level contains 2 electrons

Increase in positive charge draws electrons closer to the nucleus. Increase in the number of occupied orbitals shields electrons in the highest occupied energy level from the attraction of proteins in the nucleus.

An atom's "group" is its column position in the Periodic Table of the Elements. Elements in the same group in the periodic table have similar chemical properties. This is because their atoms have the same number of electrons in the highest occupied energy level.

true
The group numbers tell the number of valence electrons. Without looking on the group number you can also tell the number of valence electrons by looking at the highest energy level in the electronic configuration.
The electron configurations of all the elements in a group have the same number of valence electrons. Valence electrons are the electrons found in the outermost shell of an element.
