Concept introduction:
Atom is the smallest fundamental unit of matter. Atom is made up of subatomic particles like electrons, protons and neutrons. Protons and neutrons are present in the nucleus and called nucleons. Electrons are present in orbitals, outside the nucleus. During chemical transformations electrons are being exchanged between the elements.
Atomic number is the number of electrons or the number of protons present in that atom. It is the main characteristic of an atom on which most of the properties are dependent.

- An isotope of an element contains 63 protons and 91 neutrons. (a) Identify the element and give its symbol. (b) Give the elements atomic number. (c) Give the mass number of the isotope. (d) This element has two naturally occurring isotopes. Given the information in the table, calculate the atomic weight of the element. (e) In which region of the periodic table is the element found? Explain your answer. (f) Is the element a metal, metalloid, or nonmetal? Explain your answer. (g) This element, used in compact fluorescent light bulbs and computer screens, has an atomic radius of 180 pm. Calculate how long the chain of atoms would be if all the atoms in a 1.25-mg sample of this element were put into a row.arrow_forwardScientists J. J. Thomson and William Thomson (Lord Kelvin) made numerous contributions to our understanding of the atom’s structure. Which subatomic particle did J. J. Thomson discover, and what did this lead him to postulate about the nature of the atom? William Thomson postulated what became known as the “plum pudding” model of the atom’s structure. What did this model suggest?arrow_forwardGive two examples of each: a. alkali metal b. alkaline earth metal c. halogen d. noble gas e. metal f. nonmetal g. transition metal h. metalloidarrow_forward

- a. Classify the following elements as metals or nonmetals: Mg Si Rn Ti Ge Rn Au B Am Bi At Br b. The distinction between metals and nonmetals is really not a clear one. Some elements, called metalloids, are intermediate in their properties. Which of these elements would you reclassify as metalloids? What other elements in the periodic table would you expect to be metalloids?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?
