Electronegativity is what at the top of the periodic table?

Answer 1

Electronegativity is the tendency of an atom to attract electrons. Many elements have to be taken into account when comparing the electronegativity of different groups. In particular, Group 1 and group 7. Something that you need to remember is the "shielding effect" of the atoms. The more shells surrounding an atom, the greater the shielding effect.

Also, the number of electrons currently occupying the outermost shell can have an effect. For example, the group 1 element Lithium has 1 electron in its outer shell, as all group 1 elements do, and group 7 elements have 7 electrons in their outer shells. However, the difference between say lithium and potassium is that potassium has 3 shells, whereas lithium has only 1. This means that Lithium has a higher electronegativity. This is because it has a smaller shielding effect from less shells, and therefore attracts electrons faster. The best thing to remember here is that group 1 has an increasing electronegativity going up the group.

Unfortunately, i cant remember how group 7 works, but i believe it is opposite to group 1, so you'll have to carry out more research!

Answer 2

Every element on the Periodic Table has a specific electronegativity, a number which measures the degree to which that atom attracts electrons (electrons have a negative charge, so by attracting electrons, an atom will become more negatively charged, hence the term electronegativity).

Answer 3

Electro negativity increases from left to right through the periods. It decreases from top to bottom in groups.

Answer 4

From left to right across a period, electronegativity increases.

Answer 5

For example the group 1: the electronegativity decrease from the top down.

Answer 6

decreases

Answer 7

decreases

Answer 8

highest

Answer 9

Mine said it increase

Answer 10

decreases. apex.
