The sun emits electromagnetic waves at many frequencies, but mostly in the infrared, visible, and ultraviolet spectrums. What kind of energy is this?

The correct answer is - radiant energy.

Explanation:

Radiant energy is the collection known as electromagnetic waves or electromagnetic radiation spectrum. The electromagnetic spectrum includes different radiations that are visible light, UV light, IR, radio waves, and others.

Photons are little packets of energy or particles that form the electromagnetic radiation. Solar energy is another term for this type of energy.

Thus, the correct answer is - radiant energy.

Explanation:

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
