Which one of the following explains why potassium is more reactive than lithium?• The outer electron in potassium is closer to the nucleus and is shielded by fewer inner shells of electrons.•This means there is a stronger attraction between the positively charged nucleus and the negatively charged outer electron.•This makes it easier for potassium to lose its outer electron compared to lithium.• The outer electron in potassium is further away from the nucleus and is shielded by more inner shells of electrons.• This means there is a weaker attraction between the positively charged nucleus and the negatively charged outer electron.• This makes it easier for potassium to lose its outer electron compared to lithium.• The outer electron in lithium is further away from the nucleus and is shielded by more inner shells of electrons.• This means there is a weaker attraction between the positively charged nucleus and the negatively charged outer electron.• This makes it easier for lithium to lose its outer electron compared to potassium.

Fluorine, chlorine and bromine are elements in Group 7 of the periodic table.Which one of the following statements is true as you go up the group?The attraction between the positively charged nucleus and negatively charged outer electrons decreases as the electrons become further away from the nucleus.The attraction between the positively charged nucleus and negatively charged outer electrons does not change as the electrons remain at the same distance from the nucleus.The attraction between the positively charged nucleus and negatively charged outer electrons increases as the electrons become closer to the nucleus.

What do valence electrons experience when going down a group?*1 pointGreater electrostatic attraction to the nucleus.Weaker electrostatic attraction to the nucleus.Greater electrostatic attraction to other electrons.Weaker electrostatic attraction to other electrons.

In metallic solid, the forces of attraction is between the mobile valence electrons and the   A AtomsB NeutronsC Negative ionsD Positively charged nuclei

Which one of the following explains why lithium is less reactive than sodium?• The outer electron in sodium is closer to the nucleus and is shielded by fewer inner shells of electrons.• This means there is a stronger attraction between the positively charged nucleus and the negatively charged outer electron.• This makes it harder for sodium to lose its outer electron compared to lithium.• The outer electron in lithium is closer to the nucleus and is shielded by fewer inner shells of electrons.• This means there is a stronger attraction between the positively charged nucleus and the negatively charged outer electron.• This makes it harder for lithium to lose its outer electron compared to sodium.• The outer electron in lithium is further away from the nucleus and is shielded by more inner shells of electrons.• This means there is a weaker attraction between the positively charged nucleus and the negatively charged outer electron.• This makes it easier for lithium to lose its outer electron compared to sodium.I DON'T KNOWSUBMIT ANSWER
