chemical bonding Flashcards
what is a noble gas
it has a noble gas configuration which makes them stable
what is bonding
where atoms react and chemically bond with one another
so that it achieves stability by attaining the noble gas configuration
how does atoms bond
by transferring electrons in ionic bonding
by sharing of electrons in covalent bonding
how does atoms bond in ionic bonding
between metals and non-metals
when atoms bond in ionic bonding, it exits as…
ions
how does atoms bond in covalent bonding
between non-metals and non-metals
when atoms bond in covalent bonding, it exits as…
molecules
when naming the ionic compound,
is it metal first before non-metals or non-metals first before metal

what is the structure of ionic compound
crystal lattice structure
what is the structure of covalent compound
simple molecular structure
describe the melting and boiling point of ionic compound
high mp/ bp
needed in a large amt of energy to overcome strong electrostatic FOA between charged ions
describe the melting and boiling point of covalent compound
low mp/ bp
require in a small amt of energy to overcome weak intermolecular force between molecules
describe the electricity conductivity in ionic covalent
cant conduct electricity in the solid state as it has no mobile ions
can conduct electricity in molten state because have mobile ions
describe the electricity conductivity in covalent covalent
cant conduct electricity in all states as it has no mobile electrons
describe the solubility in ionic compound
can in water
cant in organic solvent
describe the solubility in covalent compound
cant in water
can in organic solvent
what are cations
metals from positively charged ions
what are anions
non-metals from negatively charged ions
what are the 5 properties in ionic and covalent compound
exist as... melting and boiling point electrical conductivity volatility solubility in water
