Want this question answered?
Potential difference.
When an atom is of the same atomic number, atomic mass, etc. to the one on the periodic table (Lets use Boron for example) Then B is the regular atom. But if you change the number of nuetrons (from 6-to-7 or whatever number) ; because the number of protons never changes; you will get a different atomic mass, so an isotope is the atom with a different atomic mass. You write an isotope atom with the elements symbol and to the left of it you script (In the top left corner really small like an exponent) the new atomic mass. So in this case B would now be 12B. (except scripted, but I sadfully forgot how to do that on a computer....)
Isotopes can either be stable or unstable. Unstable isotopes have an uneven number of protons and neutrons. Stable isotopes have the same number of protons and neutrons. The number of usual protons in an element is found in the atomic mass, but I won't go there. (hope this helps, this is what we're learning about in our science class)
An unstable ratio of protons and neutrons.
The difference in temperatures between the Equator and the north and south poles, plus the rotation of the earth, causes the air currents.
Neutrone number difference
All isotopes of an element have the same number of protons in the atomic nucleus, which is its atomic number on the periodic table. All isotopes of an element contain different numbers of neutrons in their atomic nuclei, which causes the isotopes of an element to vary in mass number (protons + neutrons).
The difference between breccias and conglomerate is that breccias are angular and conglomerates are smooth. What causes rocks to be smooth is transportation, such as when rocks are in a stream and are worn down. Therefore transportation is what causes the difference between breccias and conglomerates.
Potential difference.
what is the causes of asthma
diffusion
Causes is actually "how" whereas consequences is "what happened" or the results or effects

fossil fuels and breathing causes carbon dioxide :)
A: difference in bias current causes the other
Pottential Difference between two things.
