Question

if the atomic number of Potassium is 19 and its mass is 39 what will be the number of electrons protons and neutrons and atoms also give its symbol and sure its electronic configuration pictorially​

Answer 1

Answer:

Explanation:

Symbol: K

Protons = 19

Electrons in an atom: 19

Neutrons: 39 - 19 = 20

Draw the nucleus at the center. Label it with 19 Protons and 20 Neutrons.

Draw a circle around the nucleus.

Put two dots opposite each other on the circle's circumference.

Draw another circle with its center at the nucleus bigger than you first circle.

Space 8 electrons around the circumference.

Draw a third circle like the other 2 only bigger.

Space 8 electrons around this circle's circumference.

Draw 1 more circle bigger than the third circle.

It has 1 electron.
