The atomic size for the element is very large.
If it is a metal it is a reactive element.
This is (somewhat) like asking if it is better to be male or female. Reproduction requires both genders, and chemical reactions require elements of high electronegativity and elements of low electronegativity.
TRUE
Barium
Electronegativity is the ability of an atom to attract towards it the electron pair of a covalent bond. An atom with low electronegativity is poor at doing this. For instance, the electronegativity of bromine is less than that of chlorine.
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.
If the difference in electronegativity is from 0.6 to 1.7, the bond will be polar and covalent.
Electronegativity - capacity to loss electrons - is representative for the reactivity of chemical elements; for metals low electronegativity is a high reactivity.
If it is a metal it is a reactive element.
Atoms with the lowest electronegativity values located on the leftmost part of the periodic table. The atom with the lowest electronegativity belongs to Francium.

TRUE
It electronegativity is 1.5
Electronegativity is not found on the Periodic Table of the Elements.
A small atomic radius corresponds more closely to a low electronegativity.
One with low electronegativity. Think potassium, sodium, magnesium, etc. Essentially, elements which are good reducing agents.
Electronegativity is a measure of an atom's ability to attract electrons towards itself in a chemical bond. It increases across a period from left to right and decreases down a group in the periodic table. Elements with high electronegativity tend to form negative ions, while elements with low electronegativity tend to form positive ions in chemical compounds.
