Answer:
Na₂O is the formula for the ionic compound "sodium oxide".
It has 2 sodium atoms and 1 oxygen atom.
The number of atoms for an element are written as a subscript after the element. "1" subscripts are not written.
The names of the elements are found on the periodic table.
Subtractive colors mixing with all three primaries will result in black.
<h3>How are the 3 primary subtractive colors combined?</h3>
Adding all three subtractive primary color filters together will absorb all the colors of the white light spectrum as appeared below. Each filter (or pigment) absorbs its harmonizing color and transmits (diffusely reflects) the others.
Primary colors union of these three results in white. The subtractive primary colors are related to the subtraction of light: cyan, magenta, and yellow, the colors used in four-color printing, the union of these results in black.
So we can conclude that the usually used subtractive primary colors are cyan, magenta, and yellow, and if you overlap all three in a successful equal mixture.

Answer:
Lewis structures, also known as Lewis dot diagrams, Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures, are diagrams that show the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule. A Lewis structure can be drawn for any covalently bonded molecule, as well as coordination compounds
