Question | Answer |
Three subatomic particles | protons, electrons, neutrons |
Protons | Positive charge, in the nucleus |
Neutrons | Neutral charge, in the nucleus |
Electron | Negative charge, flying around outside of the nucleus |
Alkali Metal | Group 1A: Li, Na, K, etc. |
Alkaline Earth Metal | Group 2A: Be, Mg, Ca, etc. |
Halogen | Group 7A: F, Cl, Br, etc. |
Nonmetal | Left of stairs: O,F, S, C, etc. |
Transition Metal | middle block: Mn, Pt, Hg, etc. |
Metalloid or semimetal | Along stairs: Si, Ge, As, etc. |
Inner Transitional Metals | Bottom Block: U, Pa, Ce, etc. |
What is the atomic Number? | The number of protons or number of electrons |
What is the mass number? | The number of protons and neutrons |
What is the atomic mass of an element? | The number of protons and electrons |
Where does the mass number not occur? | The mass number does not show on the Periodic table |
What is one way you can identify whether two different elements are similar? | If they are in the same column. |
Z=? | protons |
A=? | Protons + neutrons |
How do you calculate the atomic mass? | multiply MASS(amu)and PERCENT ABUNDANCE...then divide by 100 and don't forget units (amu) |
At room temperature, most elements are what physical state? | SOLID |
Are most elements on the periodic table metals, non-metals or metalloids? | Metals (Transitional) |
Homogenous | Crystal light and water. It is mixed but you cannot visibly see them seperately. |
Heterogenous | Dirt and Water. It is mixed and can see the two elements seperately. They are not completely mixed into each other.There are "Chunks." |
John Dalton | He made a theory in the early 1800's
-The elements are made up of tiny |
