Non-metals atoms are more reactive if they are smaller, this is because......

• The positive charge of the protons attracts the neutral charge of the neutrons more in a smaller atom.

• The positive charge of the electrons attracts the neutral charge of the neutrons more in a smaller atom.

• The positive charge of the electrons repels the negative charge of the protons more in a smaller atom.

• The positive charge of the protons attracts the negative charge of the electrons more in a smaller atom.
