Calculate the number of protons, electrons, and neutrons in an atom of the element pb with mass number 207 and atomic number 82.

# p=

#e=

# n=

Explanation:

Let be the number of protons.

Let be the number of electrons.

Let be the number of neutrons.

Atomic number is defined as the number of protons in a atom or ion.

Given,atomic number is .

So,

Since the atom is electrically neutral,number of protons and electrons are equal.

So,

The atomic mass is the sum of neutrons and protons.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
