Answer 4

Is it C?

Answer 5

Looks like you need to know how the number of protons, neutrons and electrons affect the outcome of the bonds they make

Answer 6

I don't personally know that. But if they are asking this to you, on a test/quiz/hw/lesson then they should have showed something like this to you that explained it

Answer 7

they did but it was a while back like about 3 months ago :P i forgot ;-;

Answer 8

but thanks for your help, i'm gonna go to bed now, night. :)

Answer 9

Isotopes have same number of protons, but different number of
neutrons. Also they are same element.

There are isotopes of Li and Be

Okai so
The the uniqueness of an element is brought about by the no. of protons. That is no. of protons is different in each element.
In an element no. of protons = no. of electrons.
Even though A and B has the same no. of protons it doesn't have the same no. of electrons and no. of neutrons. So that makes A and B 2 different elements.
Considering C and D they both have the same no. of protons and electrons. But their no. of neutrons are unequal.
Isotopes are when elements have same no. of protons , same no. of electrons and different number of NEUTRONS! SO that's it !
That makes C and D isotopes.
So the answer would be C yeah ?

Answer 12

Yes!
Thanks! May you help me with some more?

Answer 13

Yeah hopefully ! If I know yes ! :)
