Answer:
different from the number of their neutrons
Explanation:
They each have one single proton (Z = 1), but differ in the number of their neutrons. Hydrogen has no neutron, deuterium has one, and tritium has two neutrons. ... Their nuclear symbols are therefore 1H, 2H, and 3H. The atoms of these isotopes have one electron to balance the charge of the one proton.
Answer:
1.6 × 10²³ molecules of N2O5
Explanation:
To find the amount of molecules from the amount of moles of a substance we simply multiply the amount of moles by Avagadro's number.
0.27mol × 6.02×10²³ = 1.6 × 10²³ molecules of N2O5
Answer:
Explanation:
1)6
2)0
3)2
4)2
r the no. of atoms present in the molecules
