Question

Find out the following for Potassium-
I. Atomic Number
II. Mass Number

Answer 1

Hint: Potassium is a chemical element with symbol K (from Neo-Latin kalium). Potassium is a delicate silvery-white metal that may be sliced with a knife with minimal effort. In just seconds of exposure, potassium metal interacts with ambient oxygen to create flaky white potassium peroxide. It was initially separated from potash, or plant ashes, from whence it gets its name.

Complete answer:
The total number of protons and neutrons (collectively known as nucleons) in an atomic nucleus is known as the mass number, also known as the atomic mass number or nucleon number. It is roughly equal to the atom's atomic mass (also known as isotopic mass) given in atomic mass units. Because protons and neutrons are both baryons, their mass number A is the same as the nucleus' baryon number B. (and also of the whole atom or ion). For each isotope of a chemical element, the mass number is different. As a result, the number of neutrons (N) in a particular nucleus is equal to the difference between the mass number and the atomic number Z:
N = A - Z.
Mass number of potassium is 39
In the Earth's crust, potassium is the sixth most prevalent element. Potassium is required for survival. Potassium ions may be present in every cell in the body. Maintaining fluid and electrolyte balance is critical. The number of protons and neutrons in an atom are added to calculate the element's mass number.
The atomic number of potassium is 19.
Mass number = Protons + Neutrons
Number of mass = 19 + 20
And hence the atomic number of potassium is 19 and has a mass of 39 amu.

Note:
Potassium ions are required for all live cells to operate properly. Normal nerve transmission requires the passage of potassium ions across nerve cell membranes; potassium shortage and excess can both cause a variety of indications and symptoms, including an irregular heart rhythm and other electrocardiographic abnormalities. Potassium is found in abundance in fresh fruits and vegetables. The body reacts to an increase in blood potassium levels caused by dietary potassium by shifting potassium from outside to within cells and increasing potassium excretion by the kidneys.
