Periodic Table
What is the first element on the periodic table
Hydrogen
If a cup has 100 ML of space but the liquid inside takes up half how much ML of liquid is in the cup
50 ML
this theory explains how solid gases and liquid behave
KMT
how many electrons can fit in 3 shell of a bhor model
18
This phase of matter does not have a shape but when put in a glass or a container it does
Liquid
What is the symbol for helium
He
This measurement used for to measure the volume of liquids
ML
Particles in states of matter are always doing this
Which part of the bhor model have electrons
The shell
this phase is tightly packed
solid
What element has the atomic mass of 72.6
Germanium
if a amazon box is 5 cm by 2 cm by 4 cm what is the volume
What state of matter is it when all the particles are still
Solid
Does every ring have the same number of electrons
No
this phase moves fast and can move freely cause the particles are far apart
Gas
This element is mainly used in construction and has the atomic mass of 55.8
Iron
To find the volume of a cylinder you have to multiply the area of the base by what
The height
When heat is added to a substance the particels do what
Move Faster
how do you get the numbers of neutrons in a atom
mass minus atomic number
when a gas changes into a liquid it is
condensation
The elements in this group found in the second group of the periodic table are known for being really reactive especially with water.
alkali metals
This unit is used to measure 1 meter
1 m3
This state of matter has particels that move fast and are far apart
Gas
what does date run bs stand for
dalton atom
Thomson electron
rutherford nucleus
bhor shell
the solid changes into a gas skipping the liquid phase this is
sublimation
