What is proton number z ?
number of protons in the nucleus
2
New cards
What is number of electrons in the atom equal to
the proton number
3
New cards
Number of electrons in outer shell determines ?
Chemical properties of an element and what sort of element it is
4
New cards
Atomic number defines the
Chemical identity
5
New cards
Atomic number (Proton number) =
Number of protons
6
New cards
[A] = Number of protons + number of neutrons
[A]=
[A]=
[A] = Mass number
7
New cards
Isotopes are ...
atoms of the same element with different number of neutrons but same of protons
8
New cards
Isotopes of the same elements react
Chemically the same due to same electron configuration
9
New cards
Why might mass number vary in isotopes
Different number of neutrons in their nuclei
