An element's atomic number is 86. how many protons would an atom of this element have

This element have 86 numbers of protons.

Explanation:

Atomic number is defined as the number of protons or number of electrons that are present in an atom.

It is denoted by Z.

Atomic number = Number of electrons = Number of protons

Mass number is defined as the sum of number of protons and neutrons that are present in an atom.

It is denoted by A.

Mass number = Number of protons + Number of neutrons

We have, element whose atomic number is 86.

Atomic number = Number of protons = 86

This element have 86 numbers of protons.

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
