Answer:
The number of particles in the 41.8g sample of Bismuth is 12.044 × 10²³
Explanation:
The water cycle does not ensure that we have water. We must HAVE water to cause water cycle.
Evaporation, then condensation, and finally precipitation.
This would happen in order.
Hope this helps!
Answer:
11
Explanation:
Data obtained from the question include:
Mass number = 23
Neutron = 12
Atomic number =.?
Next, we shall determine the number of protons present in the element.
This can be achieved by doing the following:
Mass number = Proton + Neutron
Mass number = 23
Neutron = 12
Proton =...?
Mass number = Proton + Neutron
23 = Proton + 12
Collect like terms
Proton = 23 – 12
Proton = 11
The atomic number of an element is equal to the proton number.
Atomic number = proton number
Proton number = 11
Atomic number = proton = 11
Therefore, the atomic number is 11.
