Answer:

Cl + e-  → Cl-

Explanation:

The electrically neutral chlorine has 17 protons and 17 electrons, 7 of which are in its outer energy level. When an electron is added to a chlorine atom to complete its outer energy level it has more electrons than electrons. Electrons are negative and that is why the charge of chlorine becomes -1

You are left with a chloride ion, so you started off with a chlorine atom.

calculate the number of coulombs of positive charge in 250cm 3 of (neutral) water. (hint: a hydrogen atom contains one proton; a
Sidana [21]

Number of coulombs of positive charge in 250cm^3 water is 1.3×10^7 C

The volume of 250 cm^3 corresponds to a mass of 250 g since the density of water is 1.0 g/cm^3

This mass corresponds to 250/18 = 14 moles since the molar mass of water is 18. There are ten proton (each with charge q = +e) in each molecule of H_{2}O So,

Q = 14NA  q =14(6.02×10^23)(10)(1.60×10^−19C) = 1.3×10^7 C.

Mass is the quantity of matter in a physical body. It is also a measure of the body's inertia, the resistance to acceleration when a net force is applied. An object's mass also determines the strength of its gravitational attraction to other bodies.
