what element has an electron configuration of 1s2 2s2 2p6?
neon.
the periodic table consists of ______ and_______? fill in the blanks.
columns and rows or periods and families.
list the properties of a gas and a liquid.
gas partials can move freely and are less dense and liquid partials are moved closely together and slower than gas.
if an object has the mass of 300g and the volume of 25ml, what is the density of the object?
12g/mL3
is this a positive charge or negative charge ion in the element?
Ca 2-
describe valance electrons and what does an element need to do to become stable?
valance electrons are negatively charged that relief on the outermost layer. in order for them to be stable they need to reach 0 or 8 valance electrons.
true or false, can compounds be divided physically?
false. compounds can be separated chemically.
what is the correct term for matter?
matter is everything. matter is anything that has mass and takes up space.
if an object has a density of 30g/ml3 and the mass of 509g, what is the volume of the object? round if necessary.
16.97ml
whats the difference between covalent bonds and ionic bonds?
covalent bonds share electrons while ionic bonds transfer electrons.
what is Boron's election configuration and is it stable if not what would need to happen?
1s2 2s2 p1. take away 3 valence electrons. +3
how many protons and neutrons are in the following elements?
argon, strontium, and mercury.
Ar= 18p 22n Sr=38p 50n Hg=80p 121n.
what is a physical change and what are 2 types of physical change?
a physical change is when an atom appearance is changed and melting ice, cooling water to ice and boiling water.
if an object has the volume of 54ml and the mass of 239g, what is the density of the object? round if necessary.
4.42g/mL3
what kind of charge do cations have and what kind of charges do anions have?
cations have a positive charge while anions have a negative charge.
what is the equation to find mass.
mass= density X volume.
what family is hydrogen apart of?
none! hydrogen is a part of its own family. its all alone.
what are the three states of matter?
trick question! their are four states of matter solid, liquid, gas and plasma
how would you describe density using your own words?
Density is the amount of mass in a unit of volume. density can also define the mass per unit of volume.
define ions in your own words.
the amount of elements that are lost or gained during a charge.
what is the correct number of orbitals that can be placed in the following orbitals? s,p,d,f
s=2 p=6 d=10 f=14
