(a)
Interpretation:
Which of the element that is highlighted is a halogen has to be determined.
Concept Introduction:
Periodic law states that if the elements are arranged in increasing order of
Location of an element in a periodic table can be given by the period number and the group number. The horizontal row in a periodic table where the elements are present is known as Period. The vertical column in a periodic table where the elements are present is known as Group.
(b)
Interpretation:
Which of the element that is highlighted is an alkaline earth metal has to be determined.
Concept Introduction:
Periodic law states that if the elements are arranged in increasing order of atomic number, then the elements with similar chemical properties occur at regular intervals or periodic intervals. The elements are arranged in a periodic table in which the arrangement was based on the atomic number of the elements and the elements that have similar chemical properties are positioned in vertical columns.
Location of an element in a periodic table can be given by the period number and the group number. The horizontal row in a periodic table where the elements are present is known as Period. The vertical column in a periodic table where the elements are present is known as Group.
(c)
Interpretation:
Which of the element that is highlighted is present in Group IIA has to be determined.
Concept Introduction:
Periodic law states that if the elements are arranged in increasing order of atomic number, then the elements with similar chemical properties occur at regular intervals or periodic intervals. The elements are arranged in a periodic table in which the arrangement was based on the atomic number of the elements and the elements that have similar chemical properties are positioned in vertical columns.

General, Organic, and Biological Chemistry
- One of the best indications of a useful theory is that it raises more questions for further experimentation than it originally answered. How does this apply to Dalton’s atomic theory? Give examples.arrow_forwardThe existence of isotopes violates one of the original ideas of Dalton’s atomic theory. Which one?arrow_forwardA fundamental idea of Daltons atomic theory is that atoms of an element can be neither created nor destroyed. We now know that this is not always true. Specifically, it is not true for uranium and lead atoms as they appear in nature. Are the numbers of these atoms increasing or decreasing? Explain.arrow_forward
- Titanium and thallium have symbols that are easily confused with each other. Give the symbol, atomic number, atomic weight, and group and period number of each element. Are they metals, metalloids, or nonmetals?arrow_forwardWhich pair of elements do you expect to be most similar? a. Mg and Ca b. N and Cl c. Al and C d. S and Siarrow_forwardScientists are trying to synthesize elements with more than 114 protons. State the expected atomic number of (a) the newest inert gas. (b) the new element with properties similar to those of the alkaline earth metals. (c) the new element that will behave like the halogens. (d) the new (nontransition) metal whose ion will have a +2 charge. (e) the new element that will start period 8.arrow_forward
- Do the proton and the neutron have exactly the same mass? How do the masses of the proton and the neutron compare to the mass of the electron? Which particles make the greatest contribution W the mass of an atom? Which particles make the greatest contribution to the chemical properties of an atom?arrow_forwardFor each of the following sets of elements, label each as either noble gases, halogens, alkali metals, alkaline earth metals, or transition metals. a. Ti, Fe, Ag b. Mg, Sr, Ba c. Li, K., Rb d. Ne, Kr, Xe e. F, Br, Iarrow_forwardYour friend tells you about an article that he read in a tabloid that reported the discovery of a new form of carbon containing eight protons in the nucleus of its atoms. He claims that scientists are eager to explore the properties of this new form of carbon. What is wrong with the tabloid's claim? a. Nothing. The claim is believable. b. The claim must be false because an atom with eight protons would be oxygen, which is already known. c. The claim must be false because all forms of carbon are already known.arrow_forward
- Explain the operation of a cathode-ray tube. Describe the deflection of cathode rays by electrically charged plates placed within the cathode-ray tube. What does this imply about cathode rays?arrow_forwardThe elements that lie close to the “stair-step” line as shown below in blue are called .arrow_forward
