Based on each family's ability to either gain or lose
electrons, predict what might happen if an element in Group 1
came into contact with an element in Group 17.

Choose

1. The metal would lose two electrons and the non metal would gain two electrons

2. The metal would lose one electrons and the non metal would gain one electrons

3. The metal would gain one electron and the non metal would lose one electron

4. The metal would lose one electrons and the non metal would gain two electrons

5.No electrons would be exchanged as one family is noble

2. The metal would lose one electrons and the non metal would gain one electrons

Explanation:

An atom of a certain element reacts with the atoms of other elements in order to fullfill its outermost shell (called valence shell).

We notice the following:

- The elements in Group 1 (which are metals) have only 1 electron in their valence shell

- The elements in Group 17 (which are non-metals) have 1 vacancy (lack of electron) in their valence shell

This means that in order for both an atom of group 1 and an atom of group 17 to fullfill the valence shell, they have to:

- The atom in group 1 has to give away its only electron of the valence shell

- The atom in group 17 has to gain one electron in order to fullfill the shell

Therefore, the correct option is

2. The metal would lose one electrons and the non metal would gain one electrons

u i forgot the answer?

im pretty sure its b
