how many protons, nnutrons, atomic mass, mass number, and charge to each of the following have?
sodium atom
fluorine ion
stannic ion
for sodium i have
protons=11
electrons=11
neutral charge
how do i find the number of neutrons cause im pretty sure mass number is protons plus neutrons
also is this right so far?
yes, protons + neutrons = mass #
protons = electrons for NEUTRAL atom
Na
protons 11
neutrons 23-11 = 12
mass 22.99
mass number 23
electrons 11
atom has neutral charge
Now for a F ion
charge is -1, one more electron than proton
protons 9
neutrons 19-9 = 10
mass # = 19
electrons 9+1 = 10
okay but why is it -1 charge?
An electron has charge of -1
A proton has charge of +1
To find the number of neutrons in an atom, you can use the following formula:
Number of Neutrons = Mass Number - Number of Protons
For the sodium atom:
Protons = 11 (atomic number is the same as the number of protons)
Electrons = 11 (neutral charge means the number of electrons is equal to the number of protons)
Neutrons = Mass Number - Number of Protons
The atomic mass of sodium is approximately 23. The mass number is the sum of the number of protons and neutrons, so in this case:
Mass Number = 23
To find the number of neutrons, substitute the known values into the formula:
Number of Neutrons = 23 (Mass Number) - 11 (Number of Protons) = 12
Therefore, a sodium atom has 11 protons, 11 electrons (since it is neutral), 12 neutrons, and a mass number of 23.
Now let's move on to the other elements:
For the fluorine ion, we need to determine the charge first. If it is not specified, it is usually -1 for nonmetals. Once we know the charge of the ion, we can find the number of electrons. The number of protons remains the same as in the neutral atom. The mass number does not change.
For the stannic ion (tin in the +4 oxidation state), we also need to determine the charge. In this case, it is +4. Using the charge, we can determine the number of electrons and the mass number remains the same as in the neutral atom.
So, to summarize:
Sodium Atom:
Protons = 11
Electrons = 11
Neutrons = 12
Atomic Mass = 23
Mass Number = 23
Charge = Neutral (0)
Fluorine Ion:
Protons = 9
Electrons = ? (depends on the charge)
Neutrons = 10 (same as in the neutral atom)
Atomic Mass = 19
Mass Number = 19
Charge = ?
Stannic Ion:
Protons = 50
Electrons = ? (depends on the charge)
Neutrons = 68 (same as in the neutral atom)
Atomic Mass = 118.71
Mass Number = 119
Charge = ?
