Determine the number of atoms in the following chemical formulas. Make sure you list the elements, how many atoms of each element, and how many total atoms. Numbers 1 and 6 have been completed as examples. 8NaCl = 8+8=16 (To find the total number of atoms add the total number of atoms)
Na=1x8=8 (remember to multiply the subscript by the coefficient)
Cl=1x8=8

Explanation:

In a chemical formula, the symbols for each element in the compound are followed by subscripts that tell us how many of that element are in the compound.

For an example, let's look at the the formula for compound glucose:

C 6  H 12  O 6

The subscripts that follow each element's symbol indicate how many of that element are in the compound.

absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.

emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.

conduction, convection, radiation
