Question

the structure of a potassium atom is shown above. what kind of ion is it most likely to form? a a positive ion, because it will gain seven electrons b a positive ion, because it will give up an electron c a negative ion, because it will give up an electron d a negative ion, because it will gain an electron

Explanation:

Potassium is in Group 1 of the periodic table. Atoms in Group 1 have 1 valence electron. They tend to lose (give up) this electron to achieve a stable electron configuration (like the noble gases). When an atom loses an electron, it has more protons than electrons, resulting in a positive charge. So, potassium forms a positive ion (K⁺) by giving up an electron. Option A is wrong as it says gaining electrons (Group 1 atoms lose, not gain). Option C is wrong because giving up an electron makes a positive ion, not negative. Option D is wrong as potassium doesn't gain an electron (it loses 1).

Answer:

B. A positive ion, because it will give up an electron
