Question

A chemical bond formed when two atoms share two pairs of electrons is a ________ bond; it is best described as ________. A chemical bond formed when two atoms share two pairs of electrons is a ________ bond; it is best described as ________. double; ionic triple; covalent double; covalent single; covalent single; ionic

Answer 1

1

Step-by-step explanation:

Answer 2

Double/ covalent double (the other setence is repeated!)

Step-by-step explanation:

When an atom donates electrons and other gains electrons, they form ions and the bond is called the ionic bond. When the atoms share electrons between them, they form a molecule, and the bond is called the covalent bond.

The atoms can share one, two or three pairs of electrons in the same bond. If one pair is shared it's called a single bond or a covalent simple; if two pairs are shared it's called a double bond or a covalent double, and if three pairs are shared it's called a triple bond or a covalent triple.
