Could someone please help me??
1 answer:
Sum of ionisation energies is very high.
Let's check once .
Group 13 means boron family.
- Take example of Aluminium (Al)
- Atomic no 13
Electronic configuration is given by
Look at p orbital .
- It's half filled.
- So it's far stable than other group's elements except noble gases
Its first ionisation enthalpy is that much high that it needs a lots of energy to form ionic compounds by donating that.
- Second and third enthalpies becomes more and more high as it closes the nucleus.
So boron family is unable to form ionic compounds easily .
- So they prefer sharing electrons and forming covalent compounds

Answer: For a. Mass number for the particle is 0.
For b. The charge on the particle is -1.
For c. Another name for - particle is electron.
Explanation:
Beta- minus decay is the decay process in which beta-particle is emitted. The mass number of the nuclei remains same and the mass number of the particle is 0. The charge on the particle is -1 and the emitted particle is also called as electron.
For a. The mass number for the particle is 0.
For b. The charge on the particle is -1.
For c. Another name for - particle is electron.
