What elements have low electronegativity?
The elements with low electronegativity are the metals, specifically the alkali metals and alkali earth metals. The elements further to the left of the periodic table will have lower electronegativity than those farther to the right.
How is electronegativity related to corrosion?
The higher the electronegativity of a metal the less likely it is to corrode. Metals that corrode easily have a low electronegativity.
What is electronegravity?
Electronegativity - capacity to loss electrons - is representative for the reactivity of chemical elements; for metals low electronegativity is a high reactivity.
Why property makes the alkali metals very reactive?
The alkali metals have a low electronegativity and they easily loss an electron.
What can you tell about an atom that has high electronegativity?
For metals high electronegativity mean low reactivity; for halogens, C, O, N, S, etc. the meaning is high reactivity.

Why metals commonly tends to form cations?
Metals have a low electronegativity compared to nonmetals.
What makes one element more active than another?
A low electronegativity for metals and a high electronegativity for nonmetals.
Why metals have high electrongetavity than non metals?
Generally speaking, non-metals have high electronegativity and metals have low ones. Fluorine (F) has the highest electronegativity of any element, and cesium (Cs) has the lowest.

The alkali metals have a low electronegativity and they easily loss an electron.
What are the major characteristics of the metals in group one?
These metals have low density, they are extremely reactive, they are monovalent, the electronegativity is low, they react violent with water etc.Group-1 metals have 1 valence electron. They form mono cations.
Why does copper conduct heat faster then steel or brass?
Copper's conductivity properties are based on its electronegativity. Generally, all metals must have low electronegativity and ionization energies. But all metals do not have the same electronegativity levels.
What can you tell about an atom that has high electronegativity?
For metals high electronegativity mean low reactivity; for halogens, C, O, N, S, etc. the meaning is high reactivity.
Why do you usually choose copper for wires and not other metals?
Copper is used because of its higher conductivity. Although silver has more conductivity then copper but it is not used because of its cost, however silver is used in some specialized equipments such as satellites. Copper or any other metals conductivity properties is based on its electronegativity. Generally, all metals must have low electronegativity and ionization energies. But all metals do not have the same electronegativity levels.
Properties of a nonmetal?
Generally, non-metals have/are: - low electrical conductivity - low thermal conductivity - lower density - brittle (in solid form) - dull (in solid form) - low melting points and low boiling points - high electronegativity - negative valency They also form they form acidic oxides, whereas metals form basic oxides.
