7.1: Ions

The number of valence .................... in an atom of an element is related to the element's group number in the periodic table.

Valence electrons are the electrons in the ............... occupied energy level of an element's atoms

To find the number of valence electrons in an atom of a representative element, simply look at its ............... number.

................................. are diagrams that show valence electrons in the atoms of an element as dots.

states that “in forming compounds, atoms tend to achieve the electron configuration of a noble gas”.

Atoms of nonmetals tend to lose their valence electrons.

An atom is electrically neutral because it has equal numbers of protons and electrons.

An ion forms when an atom or group of atoms loses or gains electrons

A positively charged ion, or a cation, is produced when an atom gains one or more valence electrons.

An anion is an atom or group of atoms with ................ charge.
