Are metals electro positive or electro negative?

Answer 1

both, electropositive metals easily donate electrons and are used to repel sharks and rays.

Metals are not renowned for their electronegativity. If you create a series of fairly common elements - starting with the most electronegative, moving through to electropositive - you would collect Fluorine, Oxygen, Nitrogen, Chlorine, Bromine, Sulfur, Carbon, Hydrogen .... and so on. As you see, no metals up the electronegative end, because they typically are more stable (lower energy) when they have lost an electron or two, whereas gaining an electron (electronegativity) often means that it would have to go into a new, larger orbital which is not energetically favorable. However, things get quite complex with the larger (higher atomic weight) metals -- useful stuff like iron -- in the transition series, due mainly to the complexity of the available/optional orbitals, as defined by the Schroedinger wave equations. Refer to the Mendeleef Periodic Table for more details.

Answer 2

Metals are electropositive because :-

1. They have very low electronegativities.
2. They have the tendency to loose electrons and form cations i.e. positively charged ions.

Answer 3

Because of the way their valence electron orbitals are structured, they tend to lose electrons to satisfy the octet rule.

Answer 4

Metals lose electrons and form positively charged ions.

Answer 5

That varies from metal to metal. Typical values seem to be somewhere between 1 and 2.5.

Answer 6

Yeah sure
