ATOMIC STRUCTURE Flashcards
The heaviest particle.
Neutron
Each orbitals can only contain a maximum of how many electrons
2 electron
basic unit of matter
atom
the nucleus contains?
protons and neutrons
very tiny particles and have a negative charge
electron
much larger and heavier than electrons and have a positive charge
proton
large heavy particle and no electrical charge
neutron
the nucleus is located at?
the center of the atom
a push or pull
force
holds nucleons together and strongest of all forces
strong nuclear force
It is the strength of attachment of electrons to the nucleus of an atom.
electron binding energy
The force that holds the neutron and protons in the nucleus of an atom.
Strong Nuclear Force
Term that denotes electrons in the outermost shell of an atom.
valence
The outermost shell electrons of the element Barium is located at what shell
p-shell
true or false: Electrons in the outermost shell carries the highest energy.
true
The force that is responsible for the decay of radioactive atoms and the emission of particle from the nucleus.
Weak Nuclear Force
most powerful for massive and slow object and weakest of all forces
gravitational force
