Chromium-50 is composed of 24 protons, 26 neutrons, and 24 electrons. Chromium-52 is composed of 24 protons, 28 neutrons, and 24 electrons.

How many electrons does Na+ ion have?

10 electrons
1: The Formation of a Sodium Ion. On the left, a sodium atom has 11 electrons. On the right, the sodium ion only has 10 electrons and a 1+ charge.

How many electrons and neutrons does sodium have?

Since sodium atoms have 11 protons, this means that a normal sodium atom has 23 – 11 = 12 neutrons. It would also have 11 electrons, but electrons weigh so little compared to protons and neutrons that the electron masses can be approximated to 0.

What is Valency of sodium?

Electronic configuration of sodium is 2,8,1. It has one valence electron. Thus, its valency is one. Chemistry.

Which of the following has 8 valence electrons?

Any element in group 18 has eight valence electrons (except for helium, which has a total of just two electrons). Examples include neon (Ne), argon (Ar), and krypton (Kr).

What is the electron configuration of sodium 11?

Ans: Electron configuration of sodium 11 is 1s 2 2s 2 2p 6 3s 1. How many valence electrons are in sodium? Ans: One valence electron.

How many protons neutrons and electrons are in a lithium 7 atom?

A lithium-7 atom contains three protons, four neutrons, and three electrons. The number of electrons in an electrically-neutral atom is the same as the number of protons in the nucleus.

What is lithium-7li?

7Li is one of the primordial elements (or, more properly, primordial nuclides) produced in Big Bang nucleosynthesis. A small amount of both 6Li and 7Li are produced in stars, but are thought to be “burned” as fast as produced. A lithium-7 atom contains three protons, four neutrons, and three electrons.
