Since sodium has atomic number 11, its electronic configuration is untill 3s1. This means the valence shell has 1 electron, so it has 1 valence electron.
8 electrons which equals the atomic number
Boron has three electrons in its outer shell
The Atomic Number tells us the position of the element in the Periodic Table. It also tells us the number of protons and electrons in an atom of that element. The Atomic Mass/Weight is different. The Atomic Mass is the total numbers of nucleons ( protons and neutrons) in the nucleus of an atom. For a given element the atomic mass can vary. This is because the nucleus may have a different number of neutrons. These different masses of a given element are named 'Isotopes'.
Yes, nitrogen forms a diatomic molecule (N2) held together by a triple covalent bond. Each nitrogen atom shares three electrons with the other nitrogen atom, resulting in a very stable molecule due to the strong bond formed by overlapping atomic orbitals.
Sulfur needs to gain 2 electrons to have the electon configuration of Argon
2
The chlorine atom has 17 protons and electrons.
8 electrons which equals the atomic number
Nickel is a metal element. There are 28 electrons in a single atom.
if it is not charged - 11.
oxygen has 6 valence electrons as indicated by the 6A above the group oxygen is in
An atomic nucleus contain protons, neutrons and electrons - not oxygen.
Carbon tetrabromide (CBr4) contains a total of 36 electrons. Each carbon atom contributes 4 electrons, while each bromine atom contributes 7 electrons. There are 4 bromine atoms in CBr4, totaling 28 electrons, along with the 8 electrons contributed by the 2 carbon atoms.
The sodium cation is Na+.
Sodium has one valence electron in its outermost shell (the third electron shell). To achieve a stable electron configuration, similar to that of the nearest noble gas (neon), sodium needs to lose this single valence electron rather than gain more. Therefore, sodium does not need additional valence electrons; it only needs to lose its one valence electron to achieve stability.
What is the atom????
