Group 1 elements are the alkali metals, which form ions wih a 1+ charge.
positive ions
monovalent elements
there is no way to tell
Group 1 elements form 1+ ions.
We haven't seen your graph. However, it is easy to say what kinds of ions elements form. Metals form positive ions and nonmetals form negative ions.
cations = positively charged ions
The ionic charges of group 1 and 2 metals are +1 and +2 respectively. Group 15 & 16 the simple mono-atomic ions are -3 and -2. Group 17 ions are -1. This can be explained by the following elemnts in groups 1 and 2 lose 1 or 2 electrons respectively to achieve a noble gas configuration whereas groups 15, 16 and 17 gain electrons (3,2 1 respectively)
Elements with nearly full valence band orbitals. These elements are on the right side of the periodic table.
ionic compounds are made up of elements that form ions. It could be either cation or anion
attraction
YES

The elements that lose electrons and form positive ions are called metals. They will lose the electrons from their highest levels of energy to gain a more positive charge and form positive ions.

It can be. An ion is an atom with more or less electrons than protons. But having 8 valence electrons (simply) means it has a full outer shell. But the noble gases already have a full shell without being an ion.
metals
Oppositely charged ions form ionic bonds.
Non-metal atoms gain an electron, or electrons, from another atom tobecome negatively charged ions. (i.e. anion)You can visit igcsechem.webs.com (advanced) or ks3science.webs.com (basic) to learn more chemistry!
