Electromagnetic radiation<span>, is a form of energy emitted by moving charged particles. As it travels through space it behaves like a </span>wave<span>, and has an oscillating electric field component and an oscillating magnetic field. These </span>waves<span> oscillate perpendicularly to and in phase with one another.</span>
The Bohr Model, which was proposed by Niels Bohr in 1913
Answer:
- 53 protons
- 131g
- Iodine
- Halogens
Explanation:
atomic no. = no. of protons
= 53 proton
mass = no. of protons + no. of
neutrons
= 53 + 78
= 131
1.00*10^3
You’d need to lower the exponent because rounding to 3 sig figs changes the 9’s to - 1000. Keep the 0’s.
Tarnish is Ag2S-silver sulfide and the oxidation state of silver is +1
