A period is a horizontal row on the periodic table.
Explanation:
Different atoms absorb and emit specific wavelengths of electromagnetic radiation and nothing in between. These absorption and emission spectra are actually used to identify atoms of elements in a substance. This phenomenon is explained by Bohr's theory of quantized energy levels in an atom – called orbital levels. When an electron 'jumps' from a lower to higher orbital level, it absorbs a specific wavelength of electromagnetic radiation specific to the ‘jump’. Vice versa, when an electron 'jumps' to a lower orbital level is emits an equivalent and specific wavelength of electromagnetic radiation.

Answer:
202,020 pennies
Explanation:
The amount of pennies in 1 dollar is 100.
Basically, you just multiply the whole dollar amount (2020) by 100 and then add 20 to find the amount of pennies.
(2020)(100)+20= 202,000+20= 202,020 pennies.
