First, find moles of gold given the mass of the sample:
(35.9g Au)/(197.0g/mol Au) = 0.182mol Au
Second, multiply moles of Au by Avogrado's number:
(0.182mol)(6.02 x10^23)= 1.10x10^23 atoms Au
Answer:
Polar molecules occur when there is an electronegativity difference between the bonded atoms. Nonpolar molecules occur when electrons are shared equal between atoms of a diatomic molecule or when polar bonds in a larger molecule cancel each other out.
Explanation:
Polar molecules occur when there is an electronegativity difference between the bonded atoms. Nonpolar molecules occur when electrons are shared equal between atoms of a diatomic molecule or when polar bonds in a larger molecule cancel each other out.
There are 4 types of orbitals. The s, p, d and f orbitals. They can contain a maximum of 2, 6, 10 and 14 electrons, respectively. So, for the 1s energy level, you would expect a maximum of 2 electrons. That includes elements 1 and 2, hydrogen and helium. <em>These are the only 2 elements in the first period.</em>
