Two isotopes of the same element will have the same number of but a different number of (2 points)
question 1 options:

1) neutrons, protons.
2) protons, electrons.
3) protons, neutrons.
4) neutrons, electrons.

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
