An isotope is a chemical structure that is highly similar to its parent isotope, with the difference lying in the number of neutrons that the compound has. As an example, carbon has the elemental number 6, which means it has 6 protons. 12-carbon will have 6 protons and 6 neutrons, while 14-carbon will have 6 protons and 8 neutrons. The differing neutron numbers will have an affect on the nuclear reactions between these two compounds, but their chemical reactions will remain the same as the neutrons will not affect how they perform on a chemical level.
Answer:
Explanation:
It is A. that is the only one that really makes any sense to me.
I do hope I helped you! :)
Answer:
Attraction
(e-) ---> <--- (H+)
Repulsion:
<---(e-) (e-)-->
Neutral:
(e-) (Helium)
Explanation:
Accordingly to coulomb's law:
In the attraction, the hydrogen without an electron has a positive charge and needs to be fulfilled with a negative charge found in an eletron.
In the repulsion, both electrons has the same charge and repulse each other.
In the neutral case, the Helium is highly stable therefore the electron is not attracted.
Gas. Molecules in gas are able to move and vibrate around each other more freely than the molecules in liquids and/or solids due to the great amount of space in between them. Hope this helps! :)
