Question

question 14 (1 point) fill in the symbol, mass, protons, neutrons, electrons for each of these using the periodic table you learned in class or from the link. assume all of these atoms are neutral. name symbol mass protons neutrons electrons potassium blank 1: blank 2: blank 3: blank 4: blank 5:

Explanation:

Step1: Find potassium on periodic table

Potassium has symbol K, atomic number 19.

Step2: Determine protons

Atomic number = number of protons. So, number of protons = 19.

Step3: Determine electrons

For a neutral atom, number of electrons = number of protons. So, number of electrons = 19.

Step4: Determine mass number and neutrons

The most common isotope of potassium has a mass number of 39. Neutrons = mass number - protons. So, neutrons = 39 - 19 = 20.

Step5: Fill in the table

Symbol: K, Mass: 39, Protons: 19, Neutrons: 20, Electrons: 19

Answer:

Symbol: K
Mass: 39
Protons: 19
Neutrons: 20
Electrons: 19
