So... for the element of CHLORINE, you already know that the atomic number tells you the number of electrons. That means there are 17 electrons in a chlorine atom.

Li+ has only two electrons on the outermost shell. Li has +1 valency so it ionises as Li+ion. Therefore it has only 2 electrons in its outermost shell.

Answer and Explanation: Lithium has one valence electron. It has a total of three electrons, with two in its first shell.

Stylized lithium-7 atom: 3 protons, 4 neutrons, and 3 electrons (total electrons are ~​1⁄4300th of the mass of the nucleus). It has a mass of 7.016 Da.

One mole of lithium (Li) is equal to 6.022 X 1023 atoms of lithium. A mole is a number equal to the number of carbon atoms in a 12-gram sample of...

Together, they make the formula LiF. Fluorine has seven electrons of it's own. Lithium gives up its one electron to make both atoms happy. So the fluorine atom has eight electrons, and a filled outer shell.

A mole is a unit of measurement, which equals 6.02 * 10^23. If you have a mole of cl2, then you have 6.02 * 10^23 molecules of cl2. If you want to calculate for atoms however, you can see that each molecule has two atoms of cl. Therefore you have 2* 6.02 * 10^23 chlorine atoms.

Nuclei of lithium can have 3, 4 or 5 neutrons. We call these different isotopes of lithium. Since different isotopes of an element have different numbers of neutrons (but always the same number of protons) they have different mass numbers. ... Lithium-6 and lithium-7 are both stable isotopes of lithium.

So, each unit cell has 4 atoms of each Na+ and Cl-. Hence there are total 4 molecules of NaCl in each unit cell. As the mass of -Avogadro number of molecules- of NaCl is 58.5g.

For example, a lithium atom (Z=3, A=7 amu) contains three protons (found from Z), three electrons (as the number of protons is equal to the number of electrons in an atom), and four neutrons (7 – 3 = 4).

Na is sodium. Na has 11 (+) protons and 11 (-) electrons. Cl is chlorine. Cl has 17 (+) protons and 17 (-) electrons.

Based on both the combination of a metal and non-metal, and on the difference in electronegativity, LiCl (Lithium chloride) is considered an ionic compound.

A neutral lithium atom will also have 3 electrons. The negative electrons balance the charge of the positive protons in the nucleus.
