Atoms do not look like the material that they make.
No. They each have the same properties but you can't see them and can't say that look like many together.
So as to explain the properties of atoms.
Atoms are not added but rather the material (usually silicon) is doped with an impurity like germanium to either add an extra electron (n-material) or be missing an electron (p-material) in the outer valance shell.
Wood atoms do not exist, and there are many different types of metal atoms. Look on a periodic table. Wood is a biological material consisting of a lot of molecules and atoms.
Like all material things that exist, water is made from atoms. Water is made specifically from hydrogen and oxygen atoms, elements that are in the form of gas when at stp and not combined.
Conduction is a phenomenon not a material.
atoms
The same as they look now, just cheaper material.
With only some atoms the appearance of meitnerium is not known.
atoms are made up of electrons, protons and neutrons.
2.5x10^22 atoms
No. A water molecule only consists of three atoms bonded together.
As common as dirt. Because dirt is made of atoms. Of course everything material is made of atoms.
