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.
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.
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.
You should find 16 protons, 16 neutrons and 16 electrons.
15 electrons plus or minus one electron if it is an ion
If the atom is not ionized, it must have 16 electrons to balance the electrical charge of the 16 protons.
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.
if your talking about shell that would be 3
If the atom is electrically neutral, then the number of proton will be the same as the number of electrons.
Phosphorous has 5 valence electrons. So, you need 3 more to complete it.
The first shell can hold a maximum of 2 electrons, the second shell can hold up to 8 while the third shell can also hold a maximum of 8.
8 - called valence electrons. it doesn't matter what energy level or orbital shape. a "happy atom" has 8 valence electrons
It depends on the atom. List what element the atom is from.
A stable atom has 8 electrons in its outer most valence shell. A simple way to remember this is that all atoms want to be like the noble gases which all have 8 electrons (except helium but the reason is complicated and not necessary here)
There are 8 electrons in the third energy level of a calcium atom.
The third energy level of an atom can hold eight electrons.
There are eight electrons in the third level of a chromium atom.There are four level in the chromium atom, and the fourth level, unfilled, contains 6 out of 18 electrons, in the neutral, non-ionized atom.
This would be sulfur, and the third level has 6 electrons. See the diagram linked below
2 electrons. Magnesium has 12 total, in 3 shells, 2,8,2There are two electrons in magnesium's third energy level.
13 :)
The sulfur atom has 16 electrons around its orbitals. The third energy level is the most tightly bound to the nucleus.
An atom with seven electrons will have five electrons in the second energy level.
there are 2 in the first there are 8 in the second there are 5 in the third
15
The element sulfur is element number 16, and has 6 electrons in the 3rd orbital level : 3s2, 3p4.
A boron atom has three electrons in its second energy level.
