(a)
Interpretation:
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.

Chapter 3 Solutions
GENERAL,ORGANIC,+BIO.CHEM.-MINDTAP
- A 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. The elements with atomic numbers of 93 or greater are referred to as the _________ elements.arrow_forwardThe existence of isotopes violates one of the original ideas of Dalton’s atomic theory. Which one?arrow_forward
- Your 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_forwardCan two different elements have the same atomic number? Explain.arrow_forwardQuestions 31 through 36: Percentage abundances and atomic masses (u) of the natural isotopes of an element are given. a Calculate the atomic mass of each element from these data. b Using other information that is available to you, identify the element. Percentage Abundance Atomic Mass (u) 51.82 106.9041 48.18 108.9047arrow_forward
- 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_forwardWhat is the electron configuration of Mg2+? How does its reactivity compare with neutral Mg? How do the reactivities of F- and F compare?arrow_forwardWhat does the number 36 represent on the periodic table entry for krypton? a. atomic number b. relative atomic mass c. group number d. electron configurationarrow_forward
