This postulate is valid today only in some situations.
The strong force holds atomic nuclei together.
Although Dalton's theory remains valid in modern atomic theory, there are some differences. Dalton's theory stated that atoms were indivisible and indestructible, but discoveries in modern atomic theory showed that there are subatomic particles that are smaller than the atom. Similarly, through nuclear reactions, an element's atoms can be transformed into atoms of another. Modern atomic theory includes isotopes while Dalton's theory does not have this phenomenon.
Many different theory hold modern biology together --------------------------- The answer they were looking for is 'evolution'.
bohrs theory holds that each atom consists of a small, dense, positively charged nucleus surrounded by negatively charged electrons that move in fixed, defined orbits about the nucleus, the total number of electrons normally balancing the total positive charge of particles in nucleus.
The stratosphere layer holds ozone. It is tri atomic gas. It protects us from the UV rays of the sun.
The strong force holds atomic nuclei together.
It described a nucleus surrounded by a large volume of space.
The nucleus holds both neutrons and electrons in it.
holds two atoms together
