atomic structure (chem)

Question 1

why is the extent of deflection different for protons and electrons

Answer 1

an electron has a much smaller mass than proton –> extent of deflection of electron towards the positive plate in the electric field will be greater

Question 2

what is a nuclide

Answer 2

used to describe an atomic species of which the atomic number and mass number is specified

Question 3

why are atoms said to be electrically neutral

Answer 3

no. of electrons = no. of protons

Question 4

explain the amount of energy of electrons in the innermost shell vs outermost shell

Answer 4

lowest energy (as tightly bound by nucleus); highest energy
