This is the ion selenium(2-).
2 protons and 2 neutrons (an a-particle is effectively a helium atom without any electrons).
no i cant answer it
No Element Has that kind of Configuration
The type of particle that has either more or fewer electrons than protons is an ion. Ions are called cations when they have fewer electrons than protons and anions when they have more.
102 ( the atomic #, # of protons, and #of electrons are always the same )
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
They are neutrons, protons and electrons.
Yes.An alpha particle is the nucleus of a helium atom, with no electrons. There are 2 protons and 2 neutrons.
In an atom, 10 protons and 10 electrons. (# of protons = atomic number) =)
These particles are: protons, neutrons and electrons.
Protons, neutrons & electrons
an ion
Electrons, protons, and nuetrons. electrons are outside the nucleus, and protons and nuetrons are inside the nucleus.
The atom will become negatively charged (protons are positive and electrons are negative.)
