Question | Answer |
What is an atom? | The smallest piece of matter an element can be divided into & still be that element. |
Where are the highly reactive metals located on the Periodic Table of Elements? | The 1st & 2nd columns. |
Where are the moderately reactive metals located on the Periodic Table of Elements? | Columns 3-16 and the rare earth metals are at the bottom. |
Where are the metalloids located on the Periodic Table of Elements? | Follow the stair step line in columns 13 - 17 |
Where are the moderately reactive nonmetals located on the Periodic Table of Elements? | Above the stair step line in columns 14 - 16. |
Where are the highly reactive nonmetals located on the Periodic Table of Elements? | Column 17 on the right (but not the last column) |
Where are the non-reactive nonmetals located on the Periodic Table of Elements? | Far right side (column 18) |
What increases as you go down a row (left to right) on the Periodic Table of Elements? | Atomic number / number of protons in one atom |
List properties of any element that will not change no matter what you do to it (not including a chemical reaction). | Density, melting point, boiling point, atomic number, reactivity, number of bonds with hydrogen |
How are elements put into the same group on the Periodic Table of Elements? | Based on their chemical properties (such as number of bonds with hydrogen). |
In what column number on the Periodic Table of Elements would a non-reactive colorless gas be found? | Column 18 (noble gases). |
In what column number on the Periodic Table of Elements would a highly reactive, silvery metal be found? | Column 1 (Alkali metals). |
In what column number on the Periodic Table of Elements would a highly reactive gas be found? | Column 17 (some of them are halogens). |
In what column number on the Periodic Table of Elements would a solid with some metallic properties and some non-metallic properties be found? | Columns 13 - 17 (metalloids). |
What does the number of protons in an atom "control" about the atom? | Which element the atom is / its identity |
How does the number of neutrons in an atom affect the atom? | Affects ONLY the mass of the atom. |
Where in the atom are the electrons located that will have the most impact on the reactivity of that atom? | In the valence/outer shell |
What are the electrons in the outermost shell called? | Valence electrons |
How does the number of the outer-shell electrons impact the atom? | Affects what the atom will bond with and/or how many bonds it will bond for. (They affect the level of reactivity of the atom). |
Name the states of matter and their particles' amount of force of attraction. | Solid - most
Liquid - medium
Gas - least |
Name the states of matter and their particles' amount of energy. | Solid - least
Liquid - medium
Gas - most |
List all of the properties of an element that can be seen or figured out by using the Periodic Table of Elements. | Element name, symbol, atomic #, atomic mass, mass #, # of p, # of n, # of e, # of electron shells, # of electrons per shell, state of matter @ room temp., family, group #, period #, reactivity, man-made vs. naturally occurring, metal vs. nonmetal |
If you know the level of reactivity for an element, what else does that information indicate about the element? | It indicates what family it's in & how easily it reacts with other elements. |
What chemical properties can be used to place elements in columns on the Periodic Table of Elements? | level of reactivity, number of bonds formed with hydrogen |
List silly putty, water, steel, and nitrogen gas in order of strongest to weakest bond between particles. | steel, silly putty, water, nitrogen gas |
What subatomic particle is positive? | Proton. |
What subatomic particle is negative? | Electron. |
What subatomic particle is neutral? | Neutron. |
What subatomic particles are in the nucleus of an atom? | Proton & Neutron. |
What subatomic particle orbits the nucleus of an atom? | Electron. |
How does reactivity change as you move from left to right across the Periodic Table of Elements? | It decreases. |
How do metallic properties change as you move left to right across the Periodic Table of Elements? | They increase until column 17 (they stop at column 18). |
