A and 12
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 symbol for boron is B, and a neutral atom of boron has 5 electrons.
The chemical symbol of uranium is U. Uranium has 92 electrons.
Electron configuration of uranium: [Rn]5f36d17s2
The symbol for the element with 5 electrons in its neutral state is B, which stands for Boron. Boron has an atomic number of 5, meaning it has 5 protons and 5 electrons when it is in its neutral state.
Antimony, symbol Sb has an atomic number of 51. This is the number of protons in the nucleus of an atom of Sb, and in a neutral atom it is also the number of electrons. The ground state electron configuration for antimony is: 1s22s22p63s23p63d104s24p64d105s25p3
Cl has 17I has 53 Xe has 54 and Sb has 51.
The chemical symbol of uranium is 'U' and it has 92 electrons.
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 chlorine is Cl. Atomic number of it is 17. It has 17 electrons.
The symbol for boron is B, and a neutral atom of boron has 5 electrons.
Antimony (Sb) has the atomic number of 51. The atomic number is the same as the number of protons in the atom (an the same as the number of electrons in the neutral atom).
The symbol for xenon is Xe, and a neutral atom of xenon has 54 electrons.
The chemical symbol of uranium is U. Uranium has 92 electrons.
Electron configuration of uranium: [Rn]5f36d17s2
The symbol for the element with 5 electrons in its neutral state is B, which stands for Boron. Boron has an atomic number of 5, meaning it has 5 protons and 5 electrons when it is in its neutral state.
For an neutral element that has the same number of electrons and protons, the element with 11 electrons is Na, sodium.
