Atomic Structure And Isotopes Flashcards
What does the term ‘atomic structure’ refer to in chemistry?
The arrangement of protons, neutrons, and electrons
What are isotopes in the context of atomic structure?
Atoms of the same element with different neutrons
What are the key components of atomic structure?
Protons, Neutrons, Electrons
What is the relationship between atomic structure and chemical behavior?
Atomic structure determines reactivity, Electron configuration influences bonding, Isotopes can affect stability
What is electrons mass?
Negligible - around 1/1836th the mass of a proton
What are needed as the nucleus gets bigger?
More neutrons
What is constant with the same element?
Number of protons
Do isotopes affect reactivity?
No, as isotopes have the same number of electrons
Do neutrons have any effect on reactivity?
No
