Theodore Richards; first scienstist to recieve nobel prize in Chemistry, earning the award "in recognition of his exact determinations of atomic weights of a large number of chemical elements."
<span>When an ionic bond is formed between sodium (na) and chlorine (cl), the resulting molecule is called halite (salt). Ionic bonds involve the transfer of valence electrons. When this occurs between metals and non-metals, the metal loses an electron (becoming a cation) and the non-metal gains an electron (becoming an anion).</span>
When entering a science lab which of the following should be done by science students.
D. Students must wait for their teacher to give instructions.
6. 20.0 x 17.16= 343.2m^2
Answer:
Explanation:
Given that:
The mass of sodium crystal = 4.14 g
As a result, the number of atoms in the sodium crystal is:

= 1.084 × 10²³ atoms
In the valence orbital of the sodium atom, there is just one electron.
As a result, the number of molecular orbitals produced by these atoms is= 1.084 × 10²³ molecular orbital
Because valence bands are created from occupied molecular orbitals, the number of valence bands created from the aforementioned molecular orbitals is:

= 5.420 × 10²² orbitals.
