If everything else is the same, the AAA would have a higher price (more expensive) while the BBB would most likely have a higher yield (higher return)
A metallic bond.
covalent bond
The alkali metal potassium and the halogenfluorine will form an ionic bond.
because d c-c sigma bond formed by sp2-sp2 is formed from a double bond which is stronger than that of a single bond formed by sp3-sp3.
Equal sharing of electrons in a covalent bond is called a nonpolar covalent bond. It occurs when the electronegativity difference between bonded atoms is < 0.5.
It is ionic bond
There are two complimentary reasons to check a bond's rating. If you're a risk-averse investor, checking a bond's rating indicates the bond's risk of default. These guys look for "investment grade" bonds. If you're an aggressive investor, risk equals reward: the worse a bond is, the more it pays.

A bond issuer's probability of defaulting
In simple terms, the better the rating the safer the investment.
With only 1 electron in its valence shell, the atom is likely to form an Ionic bond.
