Question

Elements in group 1 will (lose or gain) electrons to obtain a noble gas structure. How many electrons will the element gain or lose in order to obtain a noble gas structure? (5,3,7,6,1,2,4)

Answer 1

Lose and 1

That's your answer!!

Answer 2

Answer is: elements in group 1 will lose electrons to obtain a noble gas structure. They will lose 1 electron.
For example ₃Li 1s²2s¹ will lose one electron from 2s oribtal to obtain helium structure ₂He 1s².
Or sodium ₁₁Na 1s²2s²2p⁶3s¹ will also lose one electron to obtain neon structure ₁₀Ne 1s²2s²2p⁶.
