Which of the following Group 15 elements has the most metallic properties |
||||
| 1) Bi | 2) N | 3) Sb | 4) P | |
|
Pure silicon is chemically classified as a semi-metal because silicon |
||||
| 1) is malleable and ductile | 2) exhibits metallic and nonmetallic properties | 3) exhibits hydrogen bonding | 4) an excellent conductor of heat and electricity | |
|
The observed regularities in the properties of elements are periodic functions of their |
||||
| 1) atomic numbers | 2) nonvalence electrons | 3) oxidation states | 4) mass numbers | |
|
Elements in the Periodic Table are arranged according to their |
||||
| 1) atomic number | 2) relative size | 3) relative activity | 4) atomic mass | |
|
In which set do the elements exhibit the most similar chemical properties |
||||
| 1) N, O, and F | 2) Al, Si, and P | 3) Li, Na, and K | 4) H, Br, and Rn | |
|
Within Period 2 of the Periodic Table, as the atomic number increases, the atomic radius generally |
||||
| 1) decreases | 2) none of the above | 3) remains the same | 4) increases | |
|
Which of the following elements has the strongest attraction for electrons |
||||
| 1) boron | 2) sulfur | 3) oxygen | 4) aluminum | |
|
Atoms of which element has the weakest attraction for electrons |
||||
| 1) Na | 2) S | 3) Si | 4) P | |
|
As the elements in Group 2 are considered in order of increasing atomic number, the atomic radius of each element increases. This increase is due to an increase in |
||||
| 1) occupied electron orbitals | 2) ionic bonds between the valence electrons | 3) neutrons in the nucleus | 4) electrons in the outermost shell | |
|
Electronegativity is a measure of an atom's ability to |
||||
| 1) attract the electrons in the bond between one atom and another | 2) repel the protons of another atom | 3) attract the protons of another atom | 4) repel the electrons in the bond between one atom and another | |
