From the periodic table, we can see that:
At ground state, the hydrogen atom has one electron
Based on the electronic configuration, at ground state this electron should be occupying the orbital (1s)
Since (1s) is not one of the choices, therefore, the answer is "none of the above"
Answer:
I assume your talking about carbon when you say 12 so it'd be 12 grams if you are
Explanation:
The molar mass of any substance in grams per mole is numerically equal to the mass of that substance expressed in atomic mass units.
Hope this helps you some
Fission reactions generate thermal energy
Answer:
I believe it is D, Heavy ice presses on sediment causing the formation of sedimentary rock
Explanation:
Answer:
D
Explanation:
Because the atomic number is 8, we can see that it is indeed an isotope of oxygen. If the mass number is 18, this means that the protons and neutrons added together = 18, so there are 10 neutrons. It does not have an atomic mass of 15.9994 like the element on the periodic table, however, as this is a confirmed isotope and not an average.
