Copper ways more because there is more atoms in copper than aluminum

Copper ways more

# data[].attributes.body
copper has more atoms than aluminum.

# data[].attributes.body
The Copper cube has more electrons, neutrons and protons than the Aluminum cube.

# data[].attributes.body
I think copper ways more because it might have more Atoms than Aluminum.

# data[].attributes.body
I think copper has a higher mass because copper has more electrons then aluminum because aluminum has 13 electrons which could have caused it to weigh more because of the certain number

I think the copper has a  higher mass because

the copper atom has more protrons neutrons and electrons than the aluminum atom,  Please leave your opinion in the comment area

the copper has more atoms in it witch makes the weight more than the aluminum

# data[].attributes.body
copper has more mass because it is a heavy'r metal because it has more protons.

I think copper weighs more because it has 29 electrons on its enery levels compared to Aluminum that only has 13 electons. This could make it weigh more because the wieght of the electrons and protons and neutrons add up aking copper weigh more than aluminum.

weighs more because they are difrent materals and copper has more atoms so it will make copper weigh more.

The copper weighs more because it has more protons, neutrons and electrons copper has 29 and aluminum has 13.

The Copper cube has more electrons,neutrons, and protons than the Aluminum cube. The Copper cube has 29 protons and electrons and the Aluminum has 13 protons and electrons.

I think copper mass denser atoms than aluminum because with the sea dragons they needed to add less dense material to make them float. So if you have more density then it would not float and be more heavy

Because the things in copper could be made out of something heavier than the other block. Aluminum, could have things made out of it that are lighter than what copper is made out of.  So my point is that they are the same shape, and size, but could be made out of different materials that could be heavier than the other.

i think because it has more atoms and made out of a more heavier material?

# data[].attributes.subject
i think because it has more atoms and made out of a more heavier material?

I think it's because, copper has an atomic mass of 64.0 and aluminum has an atomic mass of 27.0, so

it weighs more because the atoms in copper are biger than the atoms in aluminum.

more atoms so it makes it weigh more

the copper weighs more because they are two different metals. it does not matter if they are the same shape or size.

# data[].attributes.body
I think copper has more atoms compacted together, so the block is more dense than the aluminum block. this makes the copper block weigh more.

the copper weighs more because different metals have different mass because there made of different materials

Two objects that are exactly the same size and shape can have different masses by the atoms inside of them having a higher atomic mass than the other object.
