B, hydrogen bond is formed when H is bonded to F, O and N
Answer:
potassium bromide can only conduct electricity when in an aqueous solution due to the electrostatic force between the ionic bonds
Answer: a. nitrogen
Explanation:
Nitrogen comprises of five valence electrons in its outermost shell which enables it to form triple, double and single bonds with other atoms. It can share three electrons with other nitrogen atom and form a covalent bond. Moreover, nitrogen can form multiple bonds with itself and with other elements due to its small size and high electronegativity. Nitrogen, carbon, fluorine, and oxygen are the elements with which nitrogen can form bonding.
