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.

Slav-nsk [51]

Answer:

600 cm^2

Step-by-step explanation:

The side length of one of the faces is 10 cm

The length of a side is generally noted as s.

In this problem s = 10

Area of a cube face = s^2

So the area of one face of a cube = s^2 = 10^2 = 10*10 = 100

There are 6 faces on a cube.

Area = 6 * 100 = 600
