Question	Answer	% Correct
what is the mass of a neutron	1	50%
what is the mass of a proton	1	50%
what is the charge of an electron	negative	50%
what is the charge of a proton	positive	50%
how are elements ordered in the modern periodic table	increasing atomic number	25%
how were the elements originally ordered	increasing relative atomic masses	25%
but a different number of	neutrons	25%
electronic configuration is the	amount of electrons in each shell	0%
this means they will have the same	atomic number	0%
how could he predict properties of new elements	by looking at the properties of the elements next to a gap	0%
elements in the same row all have the same number of	electron shells	0%
elements in the same column all have the same number of	electrons in the outer shell	0%
isotopes are atoms of the same	elements	0%
what determines what column elements are in now	elements which have similar properties	0%
why did mendeleev leave gaps in his table	for yet to be discovered elements	0%
what are the properties of metal	high melting points, malleable	0%
what determines what row elements are in now	increasing atomic number	0%
why did he swap iodine and tellurium	iodine has a lower atomic weight than tellurium	0%
why was mendeleev right to make his pair reversal of iodine and tellurium	iodine has similar chemical properties to chlorine and bromine so he made them line up	0%
to calculate neutrons	mass number minus protons	0%
top number un chemical symbols is a	mass number (number of neutrons plus protons)	0%
what is the mass of an electron	negligible	0%
what is the charge of a neutron	no charge	0%
botttom number is the	number of protons	0%
they have the same number of	protons and electrons	0%
what information is used to group elements now	similar chemical properties	0%
what is special about the group 0 elements	they already have stable arrangements of electrons	0%
