How Many Neutrons Does Gallium(Ga) Have?
Answer:
Gallium(Ga) has 39 neutrons for this isotope.
Explanation:
Hello, chemistry lover! today we are going to help you to find out how many neutrons gallium(Ga) have in just 3 steps.
To find out the number of neutrons for gallium(Ga),we have to have knowledge about atomic number,atomic mass,mass number of gallium(Ga)
.Click picture to see clearly.
Step-1:
●The atomic number of gallium(Ga) is the number of protons in gallium(Ga)'s nucleus.
●The atomic mass of gallium(Ga) is the average number of protons plus neutrons of all the isotopes of gallium(Ga).
●The masss number of gallium(Ga) is the number of protons plus neutrons of a specific isotope of gallium(Ga).
Step-2:
We need to convert atomic mass of gallium(Ga) to mass number of gallium(Ga) by rounding if necessary (In case of fraction) .
From periodic table,
●Atomic number of gallium(Ga) is 31.
●Atomic mass of gallium is 69.72
●To find out mass number,we need to round 69.72 to a whole number.So,by rounding,we are getting mass number of gallium(Ga).The mass number of gallium(Ga) is 70.
Step-3:
By the difference between mass number and atomic number of gallium(Ga),we get the number of neutrons in gallium(Ga).
●Number of neutrons=70-31=39
In another way,
●Mass number=Protons +Neutrons
Or,70 =31 +Neutrons
Or,70-31=Neutrons
Therefore,
Neutrons=39
Therefore,the number of neutrons in gallium(Ga) is 39 here for this isotope.Remember that neutrons are present in the nucleous of gallium(Ga) and it's charge is zero.
●Number of protons in gallium(Ga) is 31.Protons are present in the nucleus of gallium(Ga).
● Number of electrons in gallium(Ga) is 31.Remember that number of electron equals to proton in a neutral atom.Eletrons are present outside of nucleus of gallium(Ga).
