The division of atoms of Uranium is how nuclear energy is produced, and this creates smaller atoms; not long ago Sciencetist have found a smaller state of matter. The ending answer is no this is not true; early Sciencetist did not know much about atoms, but this knowledge has expanded through modern science, so a lot of old theories have become ruled out. I hope this helped, and I'm a ninth grader from California.

Why might the purified salt still not be safe to eat?

The purified salt could still not be safe to eat if it has been contaminated during handling or packaging. Additionally, additives or chemical residues from the purification process could render the salt unsafe for consumption. Lastly, improper storage conditions could lead to the development of harmful bacteria or moisture content that makes the salt unsafe to eat.


Why can't element be splitted?

Elements cannot be split because they are the simplest form of matter made up of only one type of atom. Atoms are indivisible and cannot be further broken down into smaller components while still retaining the properties of that element. This is a fundamental principle of the atomic theory in chemistry.


Does the term indivisible still describe atom?

On the contrary, the existence of the electron proved that Dalton's postulate was incorrect, and that atoms could be split into smaller particles. In fact, atoms can be further divided into quarks!


If you take a hpt during implantation bleeding can it still be negative?

Yes, it is possible to take a home pregnancy test during implantation bleeding and still get a negative result. This is because the levels of the pregnancy hormone hCG may not be high enough to be detected by the test at that early stage. It is recommended to wait a few days and retest if you think you may be pregnant.


How could a student use a magnet to indicate that combining iron an sulfur to produce the mixture of iron and sulfur is a physical change?

A mixture of iron and sulfur can be separated using a magnet- the iron will be attracted to the magnet, sulfur will not. Not the that the iron could be coated with sulfur powder so an extra step is required to remove it.
