If an atom has 16 electrons how many are in the third level?

Answer 1

16 ... if it's not ionized. A neutral atom would have 16 electrons, one negative charged electron for each positive charged proton. Now an atom does not have to be neutral, it can have more or less electrons, which is called an ion. 16 Protons would make this a Sulfur atom, which is going to try to aquire 2 more electrons to have a complete orbital shell.

Answer 2

All atoms of fluorine have 9 protons. The isotope of fluorine that has 16 neutrons is fluorine-16. This isotope is synthetic (man made), and has a half-life of about 50 milliseconds. For comparison, the only naturally occurring isotope of fluorine is the only stable isotope of this element, and it is fluorine-19, with 10 neutrons. To provide an answer, a neutral atom of fluorine will have 9 electrons in it, which is one for each proton. But fluorine is highly reactive and is never found free in nature. It will beg, borrow or steal a single electron from just about anywhere it can, and the fluorine ion we encounter will have 10 electrons in it.

Answer 3

There would be 8 on the third level. The first level contains two, and the second contains 6. Subtract 8 from 16, and you get 8.

Answer 4

You should find 16 protons, 16 neutrons and 16 electrons.

Answer 5

15 electrons plus or minus one electron if it is an ion

Answer 6

If the atom is not ionized, it must have 16 electrons to balance the electrical charge of the 16 protons.

Answer 7

Sulfur. Its atomic number is 16, which tells you the number of protons and electrons. Unless there is a + or - charge, the number of protons = the number of electrons.

Answer 8

if your talking about shell that would be 3

Answer 9

If the atom is electrically neutral, then the number of proton will be the same as the number of electrons.
