Does CH₄ have hydrogen bonding?

• yes
• no

As the elements in Period 2 of the Periodic Table are considered in succession from left to right, there is a decrease in atomic radius with increasing atomic number. This may best be explained by the fact that the —

• number of protons increases, and the number of shells of electrons remains the same.

• number of protons decreases, and the number of shells of electrons increases.

• number of protons decreases, and the number of shells of electrons remains the same.

• number of protons increases, and the number of shells of electrons increases.

Polar covalent molecules are sometimes described as “dipoles” molecules as it has 2 poles.

• metallic bond

• Hydrogen bond
• dipole-dipole forces
• london dispersion forces

• Ag+(aq) + I-(aq) → AgI(s)

• Zn(s) + 2 HCl(aq) → ZnCl2(aq) + H2(g)

• H+(aq) + OH-(aq) → H2O(l)
