Question

when electrons are added to an atom, what happens to the ions size? the ion remains the same size the ion becomes smaller the ion disappears the ion becomes larger why do group 16 ions tend to be larger than group 17 ions when forming anions? 1 point group 17 elements are more reactive group 16 elements add two electrons, while group 17 elements add only one group 16 elements have a different electron configuration group 16 elements have more protons

Explanation:

When electrons are added to an atom, electron - electron repulsion increases, causing the electron cloud to expand and the ion to become larger. For the second question, group 16 elements form anions by adding two electrons, while group 17 elements add only one electron when forming anions. The additional electron in group 16 anions leads to greater electron - electron repulsion and a larger ion size.

Answer:

1. The ion becomes larger
2. Group 16 elements add two electrons, while group 17 elements add only one
