Hello everyone let's solve this question in this question we have to find out the neutral element with same number of electrons as in the given question.
00:14
So let's get started.
00:18
So we have first one is aluminium plus 3.
00:21
Second is calcium plus 2.
00:23
Then we have cs plus then we have s2 negative.
00:29
We have s2 negative.
00:31
We have f negative r b plus and bromine, bromide ion that is b are negative.
00:40
So let us understand this.
00:43
So aluminum is atomic number 27 plus 3 means 3 electrons are gone.
00:48
So it is 21.
00:49
So the element is candium.
00:52
Calcium.
00:53
It's atomic number is 20.
00:56
Two electrons gone...
