The given element is to be classified as metals, nonmetals, or metalloids.
Concept introduction:
The elements in a modern periodic table are arranged in an increasing order of their atomic number. In the modern periodic table, the horizontal rows are known as periods and vertical columns are known as groups. There are seven periods and eighteen groups in modern periodic table.

- How many valence electrons are in each element of problem 28?arrow_forwardThe contributions of J. J. Thomson and Ernest Rutherford led the way to todays understanding of the structure of the atom. What were their contributions?arrow_forwardWhat is the modern view of the structure of the atom?arrow_forward
- The atomic mass of lithium on a periodic table is 6.94u. Lithium has two natural isotopes with atomic masses of 6.10512u and 7.01600u. Calculate the percentage distribution between the two isotopes. Pure lithium is composed of two isotopes.arrow_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_forwardOne 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_forward
- . The elements with atomic numbers of 93 or greater are referred to as the _________ elements.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_forwardWhat is meant by anuclear atom? Describe the points of Ruth erford’s model for the nuclear atom and how he tested this model. Based on his experiments, how did Rutherford envision the structure of the atom? How did Rutherford’s model of the atom’s structure differ from Kelvin’s “plum pudding” model?arrow_forward
- State the main points of Dalton’s atomic theory usingyour own words. Which parts of Dalton’s theory werelater found to be erronous? Explain why.arrow_forwardNow that you have gone through Chapter 4, go back to Section 4.3 and review Dalton’s Atomic Theory. Which of the premises are no longer accepted? Explain your answer.arrow_forwardStandard Units Define the atomic mass unit. What were the benefits of developing the atomic mass unit as a standard unit of mass?arrow_forward
