attraction of charged atoms, which are called

• Chemical bond

• Electrons

• Ions

The attraction may also involve _  electrons, which are the electrons in the outermost _.

• Valnce electrons

• Octet

• shell

• Pseudo noble gas formation

The _  are a family of elements that have very little tendency to react.

• Noble Gasses

• Pseudo Noble gas formation

• nucleus

• ion

Most of these elements have a set of eight outermost electrons, which is called a stable (a)   .

The relatively stable electron structures developed by loss of electrons in certain elements of groups 1B, 2B, 3A and 4A are called...

(a)  

 A positively charged ion is called an anion.

• True

• False

Answer explanation

cation

Elements in group 1A lose their one valence electron, forming an ion with a 1+ charge.

• True

• False
