Question

Hydrogen (H2), nitrogen (N2), oxygen (O2), fluorine (F2), chlorine (Cl2), bromine (Br2), and iodine (I2) exist in nature as diatomic molecules. What type of bond exists between the atoms in each molecule?

ionic bonds
hydrogen bonds
single or multiple covalent bonds
single covalent bonds

HELPPPP!!!

Answer 1

Single or multiple covalent bonds.
It is the same atoms, so covalent bond.
H-H,F-F,Cl-Cl, Br-Br,I-I,(every atom of all of this elements have one  unpaired electron)
O=O(atom O has 2 unpaired electrons), N≡N  (atom N has 3 unpaired electrons)

Answer 2

Answer: The correct answer is single or multiple covalent bonds.

Explanation:

Covalent bonds are defined as the bonds which are formed by the sharing of electrons between the atoms forming a compound. This bond is usually formed between two non-metals.

These can be single as well as multiple bonds depending on the number of electrons. Single bond is formed by the sharing of two electrons and multiple bonds are formed by the sharing of more than two electrons.

Ionic bond is defined as the bond which is formed by the complete transfer of electrons from one atom to another atom. These are formed between one metal and one non-metal.

Hydrogen bond is defined as the bond which is formed from the electrostatic attraction between a hydrogen atom and a more electronegative atom such as oxygen, nitrogen and fluorine.

For the given molecules, Hydrogen $(H_2)$, Nitrogen $(N_2)$, Oxygen $(O_2)$, Fluorine $(F_2)$, Chlorine $(Cl_2)$, Bromine $(Br_2)$ and Iodine $(I_2)$

Hydrogen, fluorine, bromine, chlorine and iodine will form single covalent bonds.

Oxygen and nitrogen will form double and triple covalent bonds respectively or multiple covalent bonds.

Hence, the correct answer is single or multiple covalent bonds.
