How many electrons does an atom of phosphorus-30 have?

Answer 1

It should have the same number of electrons as protons unless you are dealing with an ion. Phosphorus-30 is an isotope, so it only differs in the number of neutrons. It should have 15 electrons.
***additional information***
I don't know why I came back to this question, but I'm glad I did. I looked at some of the other answers and found that many people are telling you that the phosphorus-30 isotope has 30 electrons. Let me tell you the truth. Phosphorus-30 is an isotope. The isotopes have different numbers of neutrons, NOT electrons. The phosphorus atom has 15 electrons. The phosphide anion has 18 electrons and a -3 charge. There is no way phosphorus will have 30 electrons with only 15 protons. That would give phosphorus a -15 charge. This wouldn't happen because like charges repel each other and this many electrons with that few protons would repell each other quite a bit. So, just a normal phosphorus atom (or in this case isotope) will have 15 electrons. Don't let anyone tell you it's 30!

Answer 2

30

Answer 3

30

Answer 4

15 because the 30 is for the # of neutrons in an isotope and phosphorus is # 15 on table of elemants it has 15 protons and 15 electrons

Answer 5

15

Answer 6

15

Answer 7

30 because in phosphorus-30 the 30 refers to the isotope and the # of the isotope is also the number of electrons

Answer 8

Chemical supplies constantly react in integer ratios (you under no circumstances get a reaction wherein the ratio of reactants or products isn't a rational extensive style). From that we'd end there are discrete instruments of matter for in the event that they weren't discrete then irrational ratios could be basic place (there are various many greater irrational ratios than rational). Passing a fixed volume of electric charge into some suggestions deposits fixed and without postpone proportional quantities of matter (returned integer ratios). that's sufficient evidence from first concepts. the size of the atom might properly be calculated utilising scattering of x-rays and the size of the atomic nucleus by skill of the scattering of alpha debris. The electron density of atoms might properly be mapped utilising a scanning tunnelling electron microscope which provides a map, very equivalent to in case you measured the altitude of mountains and plotted them in 3-d could supply a representaion of the land.

Answer 9

16 electrons

Answer 10

300
