Question

Fluorine (F) and bromine (Br) are in the same group on the periodic table. How do atoms of these elements compare when they form bonds?

Both a fluorine atom and a bromine atom lose one electron, and both atoms become stable.
A fluorine atom becomes stable by losing one electron, but a bromine atom cannot become stable by losing only one electron.
Both a fluorine atom and a bromine atom gain one electron, and both atoms become stable.
A fluorine atom becomes stable by gaining one electron, but a bromine atom cannot become stable by gaining only one electron.

Answer 1

3) Both a fluorine atom and a bromine atom gain one electron, and both atoms become stable

Explanation:i got it right on the quiz

hope this helps

Answer 2

Both a fluorine atom and a bromine atom gain one electron, and both atoms become stable.

Step-by-step explanation:

The two elements compare when they form bonds in that when both a fluorine atom and a bromine atom gain one electron, they both become stable.

• Fluorine and bromine are elements called halogens.
• They both belong to group 7 on the periodic table.
• When they gain an electron each, they become isoelectronic with a corresponding noble gas.
• This gives their atom special stability.
