Answer: All of these answers are sorrect
ExplanationA scientist does all of these things while operforming a experiment
They are called isotopes.
Isotopes have the same number of electrons and protons in their unionized state. They differ in the number of neutrons. The first and simplest example is hydrogen.
The most common hydrogen has
1 proton
1 electron and
0 neutrons
It has 2 cousins
1 proton
1 electron
1 neutron
And
1 proton
1 electron
2 neutrons.
Most elements have some differences in the number of neutrons present in their nuclei. Cesium and Xenon have the most number of isotopes. Each has 36. You wonder how the atoms are held together.
The correct answer is 1 to the 3rd power
101.325 kPa = 760 mmHg.
So, 25.0 kPa is 187.515 mmHg
Electron from hydrogen
Electron from carbon
Hope this helps ☺️
