Write a brief passage describing a neutral atom of nitrogen-14 (N-14). Describe the number of
protons, neutrons, and electrons in the atom,
where each type of particle is located, and how
the terms atomic number, mass number, and
atomic mass are related to the particles. Use the
periodic table to help you.

The atomic number is specific to an element, and the element with atomic number 7 is Nitrogen.

Atomic number is equal to the number of protons or number of electrons for aa neutral atom.

Mass number is the sum of number of neutrons and number of protons.

Atomic mass is the sum of masses of all protons and neutrons.

Protons and neutrons are located in the nucleus. Electrons are located outside the nucleus in the shells.

atomic number = Number of protons =  number of electrons = 7

Mass number =  number of neutrons + number of protons  = 14

Number of neutrons = Mass number - number of protons = 14 - 7= 7

consider the reaction below.

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?

is there any options? maybe im just not seeing them but i need the options to
