Dalton’s A tomic theory . The general tenets of this theory were as follows:

Dalton’s A tomic theory . The general tenets of this theory were as follows: All matter is composed of extremely small particles called atoms.

Dalton’s A tomic theory . The general tenets of this theory were as follows: All matter is composed of extremely small particles called atoms. Atoms of a given element are identical in size, mass, and other properties. Atoms of different elements differ in size, mass, and other properties.

Atoms of a given element are identical in size, mass, and other properties. Atoms of different elements differ in size, mass, and other properties. Atoms cannot be subdivided, created, or destroyed. Atoms of different elements can combine in simple whole number ratios to form chemical compounds.

We know now that (1) an atom can be further sub-divided, (2) all atoms of an element are not identical in mass (Isotopes), and (3) using nuclear fission and fusion techniques, we can create or destroy atoms by changing them into other atoms.

Review! To find # of protons and electrons It is the atomic number, or count the P+ or E-. Copyright © 2024 SlideSpark .LLC An atom can gain or lose electrons, becoming what is known as an ion. An ion is nothing more than an electrically charged atom. Adding or removing electrons from an atom does not change which element it is, just its net charge.

Review! To find # of neutrons Subtract the atomic number from the atomic mass to determine the difference. How many neutrons does Lithium have? Copyright © 2024 SlideSpark .LLC Mass – Atomic # = Neutrons
