Which element has the ground state electron configuration [ar]4s²3d¹⁰4p⁵?

4s²3d¹⁰4p⁵ 4 in 4p⁵ shows that an element is in the 4th period, 4s²4p⁵   (2+5=7) shows that element is in 17 group, if we have p-electrons on the last level, we need to count s-electrons and p-electrons, and then we will see number of the group, where an element is.  7 s- and p- electrons on the last level, so element in 17th group. 4th period, 17th group - it is Br.

Explanation:

they all get energy from eating other animals, dead animals to be more precise.

hienas tends to steal pray from other animals. crows and vultures tend to eat dead animals and leftovers.
