How Many Neutrons Does Aluminum Have?
Answer:
Aluminum has 14 neutrons for this isotope.
Explanation:
Hello, chemistry lover! today we are going to find out how many neutrons aluminum have in just 3 steps.
To find out the number of neutrons for aluminum,we have to have knowledge about atomic number,atomic mass,mass number of aluminum.
Step-1:
●The atomic number of aluminum is the number of protons in aluminum's nucleus.
●The atomic mass of aluminum is the average number of protons plus neutrons of all the isotopes of aluminum.
●The Masss number of aluminum is the number of protons plus neutrons of a specific isotope of aluminum.
Step-1:
●The atomic number of aluminum is the number of protons in aluminum's nucleus.
●The atomic mass of aluminum is the average number of protons plus neutrons of all the isotopes of aluminum.
●The Masss number of aluminum is the number of protons plus neutrons of a specific isotope of aluminum.
Step-2:
We need to convert atomic mass of aluminum to mass number of aluminum by rounding if necessary (In case of fraction) .
From periodic table,
●Atomic number of aluminum is 13 .
●Atomic mass of aluminum is 26.98
●To find out mass number,we need to round 26.98 to a whole number.So,by rounding,we are getting mass number of aluminum.The mass number of aluminum is 27.
Step-3:
By the difference between mass number and atomic number of aluminum,we get the number of neutrons in aluminum.
●Number of neutrons=27-13=14
Therefore,the number of neutrons in aluminum is 14 here for this isotope.Remember that neutrons are present in the nucleous of aluminum and it's charge is zero.
● Number of electrons in aluminum is 13.Remember that number of electron equals to proton in a neutral atom.Eletrons are present outside of nucleus of aluminum.
●Number of protons in aluminum is 13.Protons are present in the nucleus of aluminum.
