How Many Neutrons Does Sodium Have?
Answer:
Sodium has twelve neutrons for this isotope.
Explanation:
Hello, chemistry lover! today we are going to find out how many neutrons sodium have in just 3 steps.
To find out the number of neutrons for sodium,we have to have knowledge about atomic number,atomic mass,mass number of sodium.
Step-1:
●The atomic number of sodium is the number of protons in sodium's nucleus.
●The atomic mass of sodium is the average number of protons plus neutrons of all the isotopes of sodium.
●The Masss number of sodium is the number of protons plus neutrons of a specific isotope of sodium.
Step-1:
●The atomic number of sodium is the number of protons in sodium's nucleus.
●The atomic mass of sodium is the average number of protons plus neutrons of all the isotopes of sodium.
●The Masss number of sodium is the number of protons plus neutrons of a specific isotope of sodium.
Step-2:
We need to convert atomic mass of sodium to mass number of sodium by rounding if necessary (In case of fraction) .
From periodic table,
●Atomic number of sodium is 11 (Eleven).
●Atomic mass of sodium is 22.99
●To find out mass number,we need to round 22.99 to a whole number.So,by rounding,we are getting mass number of sodium.The mass number of sodium is 23.
Step-3:
By the difference between mass number and atomic number of sodium,we get the number of neutrons in sodium.
●Number of neutrons=23-11=12
Therefore,the number of neutrons in sodium is 12 here for this isotope.Remember that neutrons are present in the nucleous of sodium and it's charge is zero.
● Number of electrons in sodium is 11.Remember that number of electron equals to proton in a neutral atom.Eletrons are present outside of nucleus of sodium.
●Number of protons in sodium is 11.Protons are present in the nucleus of sodium.
