Question

use the periodic table to explain whether the following statement is true or false
considering only the most common isotopes of each element, there is only one element that has more protons than neutrons

Answer 1

Answer:

According to Wikipedia: Other than protium (ordinary hydrogen), helium-3 is the only stable isotope of any element with more protons than neutrons.

Answer 2

Answer: the statement is false

Explanation: This is because only specific atoms my lose electrons or gain electrons, if it loses electrons it becomes positive but if it gains electrons it becomes negative for example Sulfur has a mass of 32 and a proton/ atomic number of 6 lets say you have that twice but you have a table where Sulfur is shown twice when one has a proton number of 16 and a mass of 32.

As shown by the picture any element or atom can be a isotope.
