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 element has an atomic number of 80. How many protons and electrons are in a neutral atom of the element?
Atomic number is the number of protons in the nuclei of the atoms of a given element.
The element with atomic number 76 is osmium (Os).
It has 76 protons and 76 electrons
It is osmium.

Electrically neutral elements have equal numbers of electrons and protons. A stable element has equal numbers of protons and neutrons. Thus, the answer to the question ''Do Eletrically neutral element have equal numbers of electrons and neutrons?'' depends on the stability of the element i.e. if stable then yes and if unstable than might not.
Helium has 2 protons, 2 neutrons, and 2 electrons.
Number of neutrons = Atomic mass of an isotope - Atomic number of the element The atomic number of meitnerium is 109. Each isotope of an element has a different number of neutrons.
They all have protons and electrons. And all but hydrogen have neutrons as well. The number of protons is an element's atomic number. Assuming the atom is neutral, this will also be the number of electrons. The number of neutrons can vary among isotopes of the same element.
Protons and electrons are charged particles and neutrons have no charge because they are neutral.

Neutrons. If the differ in electrons they are not neutral and if they differ in protons then they are no longer the same element as the number of protons determines the name of the element.

Helium has 2 protons, 2 neutrons, and 2 electrons.
Protons have a positive charge, electrons have a negative charge, and neutrons are neutral and have no charge.

Protons and electrons are charged particles and neutrons have no charge because they are neutral.
Neutral isotopes are atoms of the same element which have the same number of protons and electrons, but different numbers of neutrons.
In the neutral state, all atoms of the same element contain equal numbers of protons and electrons. However, most elements have atoms with different numbers of neutrons. These are called isotopes.
A neutral sodium atom consists of 11 protons, 11 electrons, and usually 12 neutrons.
Electrons are a negative charge. Neutrons are neutral.
