B) H₂
Explanation:
Only H₂ is a non-polar covalent molecule among the given options. A non-polar covalent bond forms between homonuclear atoms that are chemically bonded.
- In the formation of covalent bonds, each atom shares the valence electrons in their outer energy shells to be able to mimic the noble gases.
- In homonuclear molecules, the two bonding atoms are of the same kind and the electronegativity difference is zero.
- The covalent bond between them is a called a non-polar covalent bond.
- Here there is equal sharing of the electron pair between the pair of atoms and there is no electrostatic charge on the molecule.

Answer is A, the mass and radius of the planet.
The law of universal gravitation states that gravitational force (weight) is equal to G(m1+m2)/r, and G is a constant number. m is mass and r is radius, so the answer is A.

When a molecule loses or gains an electron it becomes an ion.
"If it gains a negative electron, it becomes a negative ion. If it loses an electron it becomes a positive ion."
