more types of atoms combined.

  • There are over a hundred elements known to date.
  • Each one of the elements is symbolized by a capital or a capital letter followed by a small letter derived from English, Latin or Greek
  • Examples are copper, gold, iron
  • The properties of a compound are distinct and different from those of the individual elements that are combined in its make up.
  • There are several millions of compounds known.
  • They are usually represented by chemical formulae.

As we can see, compounds are indeed made up of more than one types of atoms whereas an element is made up of just one single atom.

faltersainse [42]

Answer:

The web page of a university

Explanation:

A scientist can be more biased within coming to information about pretty much anything. I have had multiple science teachers who seem more biased on to something else and pretend that they're right just cause they know what they are doing.

Then the university would be a great choice because its controlled by a higher state, then also the consistency of being updated.
