Question

multiple-choice question
do elements in group 1 tend to lose or gain electrons?
□ gain 1 electron
□ lose 1 electron

Explanation:

Elements in Group 1 (alkali metals) have one valence electron. To achieve a stable electron configuration (like a noble gas), it is energetically favorable for them to lose this single valence electron, forming a +1 cation. Gaining electrons would not be favorable as they have a low electron affinity and a tendency to donate the outer electron.

Answer:

B. lose 1 electron (assuming the second option is labeled as B; if the options are just the two with the second being "lose 1 electron", then the correct choice is the "lose 1 electron" option, represented as the second checkbox option here)
