While the number nuclear protons as given is 34, and therefore we deal with the element selenium, there are 2 more electrons than protons, and therefore this species has an overall
2
−
charge.
We represent this selenide ion as
S
e
2
−
. Do I win 5 pounds?
Z= 34, therefore the atom is selenium

Hello!! My answer would be that they should add the solar panels that faces the south. Since the sun rises in the east and sets in the west, the south portion would get both sunlight from the east and west sides. I hope this helps!!
There are three subatomic particle that are present in an atom. These are electrons, protons, and neutrons. Among these three, I believe the <span>subatomic particle that plays the greatest part in determining the properties of and element would be the electron. It is what determines how the element would react in different conditions.</span>
All atoms of the same element have the same atomic number
