Section 7 1 Ions

5 section 7 1 ions objectives explain how anions form.

Section 7 1 ions. Chemical bonds form by the attraction between the positive nucleus of one atom and the negative electrons of another atom. It also describes the formation of cations from metals and anions from nonmetals. Terms in this set 25 elements within the same group of the period table behave similarly because they have the same number of what.

Section review 7 1 part a completion. A chemical bond is the force that holds two atoms together. A positively charged ion or cation is produced when an atom loses one or more valence electrons.

Formation of anionsanions are negatively charged ions formed when an atom gains one or more valence electrons. An atom is electrically neutral because it has equal numbers of protons and electrons. Section 7 1 ions valence electrons are the electrons in the highest occupied energy level.

Octet rule valence electrons electron dot structures cations group. 3 section 7 1 ions objectives explain how the octet rule applies to atoms of metallic and nonmetallic elements. Commonly the name of an anion ends in ide.

Amons halide ions 8. After reading lesson 7 1 answer the following questions. F part b 11.

Note that for metals the name of a cation is the same as the name of the element. Valence electrons are the only electrons involved in chemical bonding. Prentice hall chemistry 2005.
