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.
an osmium atom has 76 protons.
A potassium atom has 19 protons and 19 electrons. This is because the number of protons in an atom is equal to its atomic number, which for potassium is 19. Electrons in a neutral atom are equal to the number of protons.
The number of electrons should = the number of protons.
76 of each.
An osmium atom has 76 protons.
An atom of osmium has 76 protons in its nucleus.

An osmium atom has 76 of each.
Niobium only seems to have one valence electron. Why it doesn't have two like the rest of the transition metals is beyond me.
An atom of ruthenium contains 44 protons and 44 electrons. This is because the number of protons in an atom determines its identity, and for a neutral atom, the number of protons equals the number of electrons.
A potassium atom has 19 protons and 19 electrons. This is because the number of protons in an atom is equal to its atomic number, which for potassium is 19. Electrons in a neutral atom are equal to the number of protons.
Oxygen has 8 protons and 8 electrons in its atom.
The number of electrons should = the number of protons.
