chapter 4 chem test
| Question | Answer |
|---|---|
| statement that when the elements are arranged by increasing atomic number, there is a periodic repetition of their chemical and physical properties | periodic law |
| groups 1 and 2, 13 though 18, s and p blocks, group A | representative elements |
| groups 3 through 12, group B elements | transition elements |
| group 1 elements (except for hydrogen) | alkali metals |
| group 2 elements | alkaline earth metals |
| a coloumn in the periodic table | group |
| a row in the periodic table | period |
| group 17 elements | halogens |
| group 18 elements | noble gasses |
| atom or bonded group of atoms that has a positive or negative charge | ion |
| energy required to remove an electron from gaseous atom | ionization energy |
| statement that atoms tend to gain, lose, or share electrons to acquire a full set of eight valence electrons | octet rule |
| indication of an atom's ability to attract electrons in a chemical bond | electronegativity |
| group B, D-block | transition metals |
| F-block | inner transition metals |
| both metals | inner transition metals and transition metals |
| malleable and ductile, lower left and staircase properties. lustus and shiny, good conduction, malleable and ductile | metal |
| gaseous or dull and brittle solids, upper right, properties: dull gas, they are poor conductors, brittle | nonmetal |
| separate the two. properties: between the two. | metalloid |
| based on atomic mass, law of octaves, arranged by atomic mass. 1st | john Newlands |
| table in order by atomic number, most like ours, 3rd | Henry Mosley |
| arranged by atomic mass, leaving gaps to identify new elements, 2nd | Dmitri Mendeleev |
| elements in the same group have the same | number of valance electrons |
| most of the elements in groups 16 though 18 are classified as | nonmentals |
| which energy level of the period 4 transition elements is being filled with electrons? | third |
| identify the period and group of the element that has the electron configuration (Ar) 4s23d104p5 | unstable nonmental |
| what is the electron configuration of the element in group 14 and period 4 of the periodic table? | (Ar) 4s23d104p2 |
| what is the trend in atomic radii as you move from left to right across a period? | generally decreases |
| the trend in the atomic radii as you move down the group 1 elements is partially due to | shielding by inner electrons |
| in which of the following pair is the second particle listed larger than the first? | Br,Br |
| how many electrons does an atom generally need in its outer level to be the most stable? | 8 |
| which of the following electron configuration represents the most chemically stable atom? | (Ne) 3s23p6 |
