What are three important things to know about atoms?

Answer 1

there are more than three important thing to know about atoms

there is a table to memorise:

position charge mass

----------------------------------------------------------------------------------------------

protons | in nucleus + 1

neutrons |in nucleus 0 (no charge) 1

electrons | around nucleus - 0

--------------------------------------------------------------------------------------------------

there is a way to remember the charges

is you see the p in protons as the word positive

and you see the n in neutron as the word neutral your all set

hope it helped :)

Answer 2

1. Atoms are indestructible by chemical methods.

2. Atoms have in the center a nucleus composed from protons (positive charge) and neutrons (neutral). Protons and neutrons contain quarks and gluons.

3. The number of protons equal the atomic number and is the most important property of an element.

4. The nucleus contain 99 % of the Atomic Mass.

5. Around the nucleus is an electron cloud with a very complex arrangement.

6. Electrons have negative charge.

7. Electrons from the outer shell are involved in chemical reactions.

8. In normal conditions the atom is electrically neutral.

Answer 3

The three important things you should know about atoms are the number of proteins how much it equals, the number of electrons, and the number of neutrons which are the components of the atom

Answer 4

what are ten facts about atomic structure
