intro to bonding Flashcards
why are noble gases very inert (very unreactive)
noble gases are very inert (very unreactive) because they have a full outer shell of electrons so are very stable. they will not lose nor gain electrons
other elements must form …. in order to obtain this stability.
other elements must form compounds in order to obtain this stability.
Ions are?
Ions are charged particles that form when an atom gains or loses an electron
the group number in the periodic table tells us?
the group number in the periodic table tells us the number or electrons on the outer shell
metal atoms will lose … to form …
metal atoms will lose electrons to form positive ions
ionic bonding occurs between
ionic bonbding occurs between a metal and a non metal
ionic bonding definition
Strong electrostatic force of attraction between oppositely charged ions
ionic bonding definition
Strong electrostatic force of attraction between oppositely charged ions
what structure do ionic solids have
giant lattice structure
limitations in ionic diagram structure
in reality there r no gaps between ions, ions are different sizes
in ionic formula the lowest whole number ratio of ions in the lattice is used its called …
in ionic formula the lowest whole number ratio of ions in the lattice is used its called empirical formula
centre = 1, face = 1/2, edge = 1/4, corner = 1/8
covalent bonding definition
sharing of pairs of outer shell electrons between non metal atoms, each single bond contains 2 electrons this allows the bonding atoms to obtain the same arrangement as a noble gas
