The number of electrons is equal to the number of protons which determines it's atomic number. Therefore, the element with 3 electrons is the one with 3 protons which has an atomic number of three which is Lithium (symbol - Li, amu - 6.941)
Fluorine is the name of the element and has 9 electrons. Fluoride is the name of the halide ion, carries a 1- charge and has 10 electrons.
A neutral atom of fluorine contains 7 valence electrons.
A chloride ion (Cl-) has the same number of electrons as a neutral atom of the element argon (Ar).
A particle containing 6 protons, 7 neutrons, and 6 electrons is a neutral carbon atom. The number of protons determines the element, so 6 protons corresponds to carbon on the periodic table. The number of neutrons is added to determine the isotope, and the number of electrons balances the charge to make it neutral.
An oxygen atom has always 8 electrons (unless it's an ion where it has picked up 2 electrons and carries a -2 charge).In an O2 molecule there are 2*8 = 16 electrons and in an O3 molecule there are 3*8 = 24 electrons.
Each neutral atom of antimony contains 51 electrons, the same as the atomic number of antimony.
The element that contains 105 electrons is fermium, which has an atomic number of 100. This means it has 100 protons and, in a neutral atom, 100 electrons.
There is none, but a neutral atom is called a neutron. There is no neutral element.
Fluorine is the name of the element and has 9 electrons. Fluoride is the name of the halide ion, carries a 1- charge and has 10 electrons.
24 electrons, remember the atomic number of an element tells you how many protons it has. The number of protons = the number of electrons (if the atom isnt charged)
16 electrons
A neutral atom of fluorine contains 7 valence electrons.
It will have 30 protons and 30 electrons if the atom is neutral.
A neutral fluorine atom contains 9 electrons.
Yes, in a neutral atom the number of electrons and protons is equal, and it is the number of protons that determines what element the atom is. So, by looking at the number of electrons you can tell what element it is.
It depends on the specific atom. Each atom contains a specific number of protons, which determines the element, and an equal number of electrons to maintain a neutral charge.
As a neutral atom (When it is not an ion) the element argon has eighteen electrons.
