Electrons, bonding & structure Flashcards
what are energy levels
fixed distance from the nucleus where electrons are found
what are principal quantum number
describes the energy of an electron and the most probable distance of the electron from the nucleus. In other words, it refers to the size of the orbital and the energy level an electron is placed in.
what is a subshell
one or more orbitals in the same shell which have the same energy levels s,p,d,f
what is an orbital
3d description of the location of an electron at a given time
what is an ion
an atom that has gained or lost an electron to gain an overall charge
what is an ionic bond
electrostatic force of attraction between oppositely charged ions
how does the electrostatic force of an ionic bond act
in giant ionic lattices the electrostatic attraction acts in all directions and takes a lot of energy to break
what is a molecule
when two or more atoms bond together covalently
what is a covalent bond
electrostatic attraction between shared pair of negative electrons of two atoms and the positive nuclei
