What would happen if a proton were added to the nucleus of the atom? (Check all
Hunter-Best [27]

Answer:

A. It would become a different atom.

C. Its charge would increase by 1

Step-by-step explanation:

Adding or removing protons from the nucleus changes the charge of the nucleus and changes that atom's atomic number. So, adding or removing protons from the nucleus changes what element that atom is! For example, adding a proton to the nucleus of an atom of hydrogen creates an atom of helium.

3x^{2} +1=28

Step 1 : subtract 1 from both sides

3x^{2} =27

Step 2 : Divide both sides by 3

\frac{\frac{3x^{2} }{3} }{\frac{27}{3} }

x^{2} = 9

Step 3 : Find the square root of 9

\sqrt{9} = 3

x= (-3,3)

remember negative × negative = positive
