Atoms physical structure
Nucleus and orbits
When an atom in is an ionic state, it will have _____ electrons resulting in NET POSITIVE CHARGE
LOST
What is in the nucleus of an atom
electrons, protons and neutrons
When an atom in is an ionic state, it will have _____ electrons resulting in NET NEGATIVE CHARGE
GAINED
What is the atomic number
Number of PROTONS in the NUCLEUS- DEFINES THE ATOM AS A PARTICULAR ELEMENT
What are ground state atoms
They tend to have equal numbers protons and electrons.. this makes these atoms electrically neutral
what are the charges of the subatomic particles in nucleus
Neutron- neutral Protons- Positive Electrons- Negative charge
