Electromagnetic radiation, is a form of energy emitted by moving charged particles. As it travels through space it behaves like a wave, and has an oscillating electric field component and an oscillating magnetic field. These waves oscillate perpendicularly to and in phase with one another.

The source of electromagnetic waves are charged particles that begin to oscillate when acted upon by a disturbance. These oscillating particles create an oscillating magnetic field. The oscillating magnetic field then creates an oscillating electric field, and an oscillating electric field in turn creates an oscillating magnetic field.

Answer:

an atom is the smallest unit of matter or a substance.

Explanation:

the structure of the

atom consists of electrons, protons, neutrons) which makes up the nucleus is more than a hundred thousand times smaller than it's atom but makes up 99.9% of the mass of the atom.

the protons are the positively charged particles. The neutrons are the negatively charged particles. The electrons are the negatively charged particles.

the first energy level consists of two electrons. the second energy level consists of eight electrons. the 3 energy level consists of eighteen electrons. the 4 energy level consists of thirty two electrons.

What is the percent composition of NaHCO3?

Katarina [22]

Answer:- Na = 27.37%, H = 1.20%, C = 14.30% and O = 57.14%

Solution:- For the percentage composition of a compound, the atomic mass of each atoms times its subscript is divided by the molar mass of the compound and multiplied by 100.

The given compound is $NaHCO_3$ .
