1) the element symbol, and thus name. For example, H is hydrogen, C is carbon and Fe is iron.

 2) The atomic number, which is equal to the number of protons in the nucleus.

 3) Since each proton has a +1 charge, you can also figure out the number of -1 electrons in the neutral atom.

 4) The atomic mass, in atomic mass units, which is an average of 1 or more isotopes of the element.

Density is an intensive physical property because the density of a given substance does not change with the size of the sample.
almond37 [142]

True

Density = mass/volume

Suppose that a block has a mass of 20 g and a volume of 20 cm^3.

Density = 20 g/20 cm^3 = 1 g/cm^3

Now, you cut the block in half. The half-block has a mass of 10 g and a volume of 10 cm^3.

The density of the half-block is

Density = 10 g/10 cm^3 = 1 g/cm^3

The density <em>stays the same</em>, even though the size of the sample has changed.

During which change of state would the volume of a substance increase the most?
Alika [10]

Answer:

The most state has the high volume is the gas state.

So here the answer is vaporization!!!!

Explanation:

The most state has the high volume is the gas state.

So here the answer is between vaporization and sublimation???

and when the sublimation is: the change of the material from the solid state to the gas state directly without pass to liquid state from the solid first then to the gas

and the vaporization is : The change of the material from the liquid state to the gas state by heating Ex: water vaporize at 100°

here, the answer is sublimation because the difference of volume which resulted from this process is more than the volume resulted from vaporization.
