Study guide: elements and density Flashcards
Three properties of metals
good conductors, shiny, solids
two elements that are metals
copper, iron
where are metals on the periodic table
metals are on the left hand side of the periodic table
three properties of nonmetals
poor conductors, gas or liquid, reacts with metals, not shiny
three elements that are nonmetals
helium, oxygen, carbon
where are nonmetals located on the periodic table
Nonmetals are on the right-hand side of the periodic table
one property of metalloids
metalloids have both metallic and non-metallic properties
two elements that are metalloids
silicon arsenic
where are metalloids on the periodic table
they border the “staircase” (zigzag line) between the metals and nonmetals
the transition elements are located from group group _ to group _ on the periodic table
group 3
group 12
what is the formula for density?
mass dvided by volume
remember Department of Motor Vehicles
if an object has more density than water (1 g/cm3), will it float or sink?
it will sink because it’s density is greater than water.
how will energy change as a substance goes from a solid to a liquid
it will gain energy
how will energy change as a substance goes from a gas to a liquid
it will lose energy
how will energy change as a substance goes from a liquid to a solid
it will lose energy
