An osmium atom has 76 protons.
an osmium atom has 76 protons.
Atomic number 76 is Osmium, the densest element. Its atomic mass is 190. Atomic number tells you the number of protons, so 76 protons. Atomic mass tells you the sum of protons and neutrons, so there are 190-76 = 114 neutrons.
The number of electrons should = the number of protons.
protons, because the protons are positive and the electrons are negative so to have a neutral atom the protons and electrons must be balanced
76 of each.
An osmium atom has 76 protons.
By one mole of osmium, we can say that it contains 6.02 x 10 23 atom. So we can say that one osmium atom contains 76 electrons: 2, 8, 18, 32, 14, 2.

The charge of an atom depends on the electrons compared to protons. Electrons being negatively charged, protons being positive. If there are more protons, the atom is positive, and if there are more electrons, the atom is negative.
Generally an atom has the same number of protons and electrons. Nitrogen has seven protons.
A neutral atom with 49 electrons will have 49 protons. The number of protons and electrons are always the same in a neutral atom. If the number of protons is not matched by the number of electrons, then the atom is charged and is called an ion. Further, if protons outnumber electrons, the atom is positively charged and is a positive ion. For situations where electrons outnumber protons, the opposite is true. The element with 49 protons in it is indium, by the way.
