Microscopic World 2

Question 1

Electronegativity

Answer 1

A measure of the ability of an atom of the element to attract the bonding electrons in a covalent bond towards itself.

Question 2

Valence Shell Electron Pair Repulsion Theory (VSEPR Theory)

Answer 2

Electron pairs in the outermost shell of the central atom in a molecule will stay as far as possible to minimize electronic repulsions

Question 3

Octet Rule

Answer 3

All atoms tend to achieve the stable electronic arrangement of a noble gas when they form chemical bonds.

Question 4

Hydrogen Bond

Answer 4

The strong attractive force between a hydrogen atom attached to a highly electronegative atom and the lone pair on another electronegative atom.

Question 5

Polar bond

Answer 5

A polar covalent bond is a covalent bond with one bonding atom having a stronger attraction for bonding electrons than the other bonding atom.

Question 6

Crystal/crystalline solid

Answer 6

A solid material whose constituent atoms/molecules/ions are arranged in an orderly repeating pattern extending throughout the material
