atoms are made of protons, neutrons, and electrons.
Atomic number and atomic mass are not alike. Atomic number is the number of protons in the nuclei of the atoms of an element. Each element has a unique atomic number. Atomic mass is the combined masses of the protons, neutrons, and electrons of the atoms of an element. Individual isotopes of an element have specific mass numbers, which are the sum of the protons and neutrons in the nuclei of the atoms of the isotope.
they both can be changed in time.
Alike. They are both atomic particles with a positive charge.
john dalton developed the atomic theory , which he published in 1803
cells are alike in structure and composition
Both a hypothesis and a theory offer an explanation of some observed phenomenon. The difference is that a hypothesis must have confirmation to become a theory.
Liquids, like solids have a definite volume. While liquids don't have a definite shape, they can take the shape of a container which can be measured the same way as with solids.
The atomic number is the number of protons in an atom's nucleus.
only thing i could find is that the atomic number is the same
they all have smilar characteristics and similar atomic numbers.
