What can you infer about to substances that have the same atomic number but different atomic masses What term would you use to classify the two substances?

They are isotopes. They are the same element with a different amount of nuetrons, which can be determined depending upon the Atomic Mass and the atomic number, which results in the changed atomic mass.


How would you classify two substances with the same atomic numbers?

they are made up of the same element.

What can you infer about two substances that have the same atomic number but different atomic masses. what term would you use to classify these two substances?

They are isotopes (same number of protons, differing numbers of neutrons) They should therefore have the same chemical properties (same atomic number = same number of electrons), but have slightly different physical properties ( one will naturally be heavier etc).


Is 40.08 the atomic number?

No. Atomic number is always a whole number. This would be the atomic mass.


To find the number of neutrons in an atom you would subtract what?

You would subtract the atomic number from the mass number.

What are First four steps of He fusion after Be?

The first four: 1. Be 2. C 3. O 4. Ne How I found this: Since Helium (He) has an atomic number of 2, add two to the atomic number of Be. Since the atomic number of Be is 4, and the atomic number of Helium is 2, you would add four plus two, which equals six. Carbon has an atomic number of six, so therefore it would be your next answer. The formula is the atomic number of Helium plus the atomic number of element you are provided with equals the atomic number of your answer. In simpler terms: atomic number of He+atomic number= atomic number of answer
