The prefix 'di' means two. Hence two atoms make up a diatomic molecule.
Hope this helps!
Sodium is a metal and bromine is a nonmetal so they form an ionic compound
nonmetals and nonmetals form covalent compounds
Answer:
Nitrogen molecule is 28 neuclons×1.67×10-27 kg/nucleon = 4.68 д 10-26 kg. So the average speed of a gas molecule is about 500 m/sec. This is roughly the speed of sound in a gas 340 m/sec. So the average kinetic energy of the gas molecules is related to the temperature of the gas.

Answer:
- <em>The net charge of the ionic compound calcium fluoride is </em><u><em>zero (0).</em></u>
<em>Explanation:</em>
<em>Ionic compounds,</em> such as covalent ones, have zero net charge; this is, they are neutral.
Substances with net positive charge are cations and substances with net negative charge are anions.
The charges in the <em>ionic compound calcium flouride</em> are distributed in this way:
- Calcium charge: Ca²⁺: this is, each calcium ion has a 2 positive charge
- Fluoride charge: F⁻: each fluoride ion has a 1 negative charge.
- Then, the <em>net charge</em> is: 1 × (2+) + 2 × (1-) = +2 - 2 = 0.
So, a two positve charge, from one calcium ion, is equal to two negative charges, from two fluoride tions, yielding a <u>zero net charge</u>.
