atomic structure (chem) Flashcards
1
Q
why is the extent of deflection different for protons and electrons
A
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
2
Q
what is a nuclide
A
used to describe an atomic species of which the atomic number and mass number is specified
3
Q
why are atoms said to be electrically neutral
A
no. of electrons = no. of protons
4
Q
explain the amount of energy of electrons in the innermost shell vs outermost shell
A
lowest energy (as tightly bound by nucleus); highest energy
