Chemistry Ch. 6

How did Dmitri Mendeleev arrange the elements on his periodic table? By increasing atomic mass.
The idea of arranging the elements in the periodic table according to their chemical and physical properties is attributed to... A. Mendeleev B. Moseley C. Bohr D. Ramsay B. Moseley
Mendeleev noticed that properties of elements usually repeated at regular intervals when the elements were arranged in order of increasing... A. Atomic number B. Density C. Reactivity D. Atomic Mass D. Atomic mass
The periodic table: A. permits the properties of an element to be predicted before the element is discovered B. will be completed with element 118 C. has been of little use to chemists since the early 1900s D. was completed with the discovery of the noble A. permits the properties of an element to be predicted before the element is discovered.
The discovery of what elements added a new column to Mendeleev's periodic table? A. noble gases B. radioactive elements C. transition elements D. metalloids A. noble gases
What are the radioactive elements with atomic numbers form 90 to 103 called? A. the noble gases B. the lanthanides C. the actinides D. the rare-earth metals C. the actinides
The principle that states that the physical properties of the elements are periodic functions of their atomic numbers is... A. the periodic table B. the periodic law C. the law of properties D. Mendeleev's law B. the periodic law
From which of the following is it easiest to remove and electron? A. Mg B. Na C. Al D. S B. Na
Which of the following influenced your answer the most? A. Nuclear charge (number of protons) B. Valence electrons C. Inner shell electrons D. Shielding effect B. Valence electron
What is the most probable oxidation state of the alkaline earth metals? A. -3 B. +2 C. +3 D. -1 B. +2
Which of the following elements is least metallic? A. Oxygen B. Fluorine C. Sulfur D. Chlorine B. Fluorine
Which of the following has a smaller radius? A. Chlorine B. Chlorine Ion C. They are the same A. Chlorine
Which of the following is most likely to gain electrons in a chemical reaction? A. magnesium B. chlorine C. fluorine D. oxygen C. fluorine
Low ionization energy is characteristics of: A. metals B. non-metals C. metalloids D. liquids A. metals
Which of the following is the smallest? A. Ne B. F- C. Na+ D. Mg++ D. Mg++
Rank the following elements by increasing atomic radius: Sulfur, Oxygen, Neon, Aluminum 1. Aluminum 2. Sulfur 3. Oxygen 4. Neon
Rank the following elements form high to low electronegativity: Carbon, Aluminum, Oxygen, Potassium. 1. Oxygen 2. Carbon 3. Aluminum 4. Potassium
Why does Chlorine have a higher ionization energy than Sulfur? Because Chlorine only needs 1 electron to become full, but Sulfur needs 2 so chlorine has more desire to gain an electron.
Why do the noble gases lack electronegativity values? Because they don't have a desire to gain electron
Indicate which element in each pair has the smaller atomic radius. a. Na or Li b. Sr or Mg c. C or Ge d. Se or O a. Li b. Mg c. C d. O
Indicate which element in each pair has the lowest ionization energy. a. Li or B b. Mg or Sr c. Cs or Al a. Li b. Sr c. Cs
Indicate which is the largest in each pair. a. Na or Na+ b. S or S2- c. I or I- d. Al or Al3+ a. Na b. S2- c. I- d. Al
Which orbital (s, p, d, f) of the following elements is filling? a. Transition metals b. Metals in group 1 and 2 a. d b. s
The most distinctive property of the noble gases is that they are... A Metallic B. Radioactive C. Metalloids D. Largely unreactive D. Largely unreactive
