there is no direct evidence but its a theory but can be proven
Synthetic diamonds have the same hardness as real diamonds because they are made of the same material, carbon atoms arranged in a crystal structure. Both synthetic and real diamonds are the hardest natural material known, scoring a 10 on the Mohs scale of mineral hardness.
No, the chlorine atoms do not return the electrons to the sodium atoms.
No, it is not possible to cool a real gas down to zero volume due to the effects of quantum mechanics. As a gas is compressed and its volume decreases, the pressure and temperature would increase. Eventually, at a certain point known as the absolute zero of temperature, the gas would turn into a liquid or solid, rather than occupying zero volume.
you see magnets are really boring and you who cares because appartently you will be using this all the time in real life
No, real diamonds do not float in water because they are very dense and sink to the bottom. The high density of diamonds is due to their tightly packed carbon atoms, which makes them heavier than water.
ATOMS are real life examples of atoms. They do exist.
yes, they are.
Atoms and moles are used in laboratories.
1914
No, they had been shown to be real long before Einstein was born.
Atom is not an "invented unit". Atoms are quite real.
It is a liquidU A LIE!the real answer is SOLID
If atoms of same element combine, we say that element is existing in its real state (or simply a molecule of that element is formed). If two atoms of different elements combine, a compound is formed.
In HCl2 are 1+2=3 atoms, so in 2HCl2 are 2*3=6 atoms, HOWEVER this is NOT the formula of an existing compound. HCl (with 2 atoms per molecule) is a real compound formula.
What about them? You didn't ask a real question, you know. Here are some links that might help
there are 20 im am a real scientist
