Answer:
Pure compounds include elements and compounds where a combination of two or more pure substances is a mixture. Only one type of atom comes in the form of a pure element. Multiple atoms consist of a molecule and different atoms consist of a compound. These are all pure substances and individually.
Wouldn't be a then not c if both were solutions.
Answer:
10 Neutrons
Explanation:
Atomic Mass = # of Protons + # of Neutrons
Atomic Number = # of Protons in nucleus and what element
20 = 10 protons + x # of neutrons
10 = x # of protons
1. The name of this element is Carbon because there are 6 electrons in the shell.
2. Sorry I didn't learn that. And I don't know.
1. A metal is a solid substance, usually hard. On the other hand, a non-metals is a solid or gaseous material, in which the metallic properties are absent.
2. When a new substance is formed at that time we can understand that chemical reaction has taken place. It can't be reversed.
4. Neutron = no charge
Electron = negative
Proton= positive
5. Nucleus has a positive charge.
6. An atom is bigger. Because electrons are what takes up space in atoms, the result is that the size of the biggest filled orbital determines the size of the atom or ion.
