Isotopes of an element have the same number of protons but different numbers of what? I have no idea what subject to put this under qwq

Isotopes is a phenomenon whereby atoms of the same element exhibit different mass numbers but have the same atomic number.I hope this helps... Thank you for the question

the correct answer is option d

explanation:

i was wrong its d because they dont use cm when calculating square roots

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.
