The Electronegativity or pauling is its reactivity, aka the more likely it is to steal an electron. so if it doesnt have ANY reactivity like helium, there is no chance it will steal one. therefore its helium.
The least reactive elements are the noble gases since they have a full valence shell and thus require a lot of energy in order to form bonds. For metals, reactivity increases as you move down a group and as you move leftward within a period. The trend within a period is due to the increase in ionization energy caused by the decrease in electrons needed to be lost in order for an element achieve a full valence electron shell. The trend within a group is due to the valence shell being further away from the nucleus, resulting in less attractive forces and thus less energy needed for reaction.
For nonmetals, the trends are reversed. Reactivity as you move up a group and as you move rightward within a period. As you move up a group, the element increases in electromagnetism and thus increasing its reactivity. As you move across a period, there is less electrons needed to be received in order for the element to achieve a full valence shell hope this helps hun
personality it’s not about looks or how much you wiegh or anything all that doesn’t matter it’s all about what’s on the inside none of that matters if you have a good personality:)
A. potential energy. It can't be any of the above questions. When the automobile burns gas it converts the potential energy into chemical energy which intern gets converted into mechanical energy and then into kinetic energy.
I would have thought it would be Chemical potential energy, which is referring to the energy between the bonds in the molecule. Hoped this helped.
