Gallium element with symbol Ga has an atomic number of 31.
Electrons start filling orbitals in increasing energy levels.
First energy shell contains the s orbital which can hold only 2 electrons.
Second energy shell contains a both p orbital and s orbital, p orbital can hold upto 6 electrons, so a total of 8 electrons in the 2nd shell.
Third energy shell contains s, p and d orbital. d orbital can hold upto 10 electrons, so the third shell can hold up to 18 electrons.
electronic configuration of Ga is 1s^2 2s^2 2p^6 3s^2 3p^6 3d^10 4s^2 4p^1
we are asked to write in the condensed form, which means we have to write the noble gas with the nearest electronic configuration to Ga.
Noble gas with electronic configuration closest to Ga is argon with atomic number 18.
Ar - 1s^2 2s^2 2p^6 3s^2 3p^6
Ga in condensed form - [Ar] 3d^10 4s^2 4p^1
Answer:
i. pretty sure its 17.03052
Answer: The differences between mass and weight is that mass is the amount of matter in a material, while weight is a measure of how the force of gravity acts upon that mass.
(happy to help)
Explanation:
Higher energy of reactants, state of transition , lower energy of product
