This is the ion selenium(2-).
The element with 26 electrons and protons is iron (Fe).
2 protons and 2 neutrons (an a-particle is effectively a helium atom without any electrons).
The elemental symbol that represents a subatomic particle composition of 80 neutrons, 56 protons, and 54 electrons is Ba (Barium).
a bromine ion will have 36 electrons and a -1 charge
Protons and neutrons are found in the nucleus. While these are theoretically composed of quarks (conversely even more massive particles), quarks do not exist in a free state so are not "fundamental particles" by definition.
Se
Se2- anion
Se2- anion
The element with atomic number 34 is selenium (Se) and when it accepts two electrons it forms Se-2 ions which has 34 protons and 36 electrons with the electronic configuration 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6
Yes.An alpha particle is the nucleus of a helium atom, with no electrons. There are 2 protons and 2 neutrons.
They are neutrons, protons and electrons.
In an atom, 10 protons and 10 electrons. (# of protons = atomic number) =)
These particles are: protons, neutrons and electrons.
Electrons are the fastest moving particles among protons, neutrons, and electrons.
Protons, neutrons & electrons
an ion
An ion is a particle that has an unequal number of protons and electrons, resulting in a net positive or negative charge.
