The chemical symbol of chlorine is Cl. Atomic number of it is 17. It has 17 electrons.
Xe, 54
For an neutral element that has the same number of electrons and protons, the element with 11 electrons is Na, sodium.
Atomic number of lead (Pb) is 82. So there are 82 protons and 82 electrons
Cl has 17I has 53 Xe has 54 and Sb has 51.
To be neutral, Bromine (atomic symbol Br) has 35 electrons. Ions have more or less.
The symbol of a boron atom is "B", and the number of electrons in a neutral atom is the same as the number of protons, which equals the atomic number of boron: 5.
The chemical symbol of uranium is 'U' and it has 92 electrons.
A and 12
B and 5 electrons
The chemical symbol of uranium is U. Uranium has 92 electrons.
Xe, 54
Electron configuration of uranium: [Rn]5f36d17s2
For an neutral element that has the same number of electrons and protons, the element with 11 electrons is Na, sodium.
The atomic number which is equal to the number of protons or electrons in a neutral atom.
Atomic number of lead (Pb) is 82. So there are 82 protons and 82 electrons
Cl has 17I has 53 Xe has 54 and Sb has 51.
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)
