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.
Chemical properties of the elements repeat themselves at regular intervals because of the electronic configuration. The elements that are present in a Group have similar chemical properties. This is because the outer-shell electronic configuration will be the same.
The periodic table has all the elements that can be distinguished based on the outer-shell electron. If the outer-shell electron is present in s subshell, then the elements are present in s area of periodic table. If the outer-shell electron is present in p subshell, then the elements are present in p area of periodic table. If the outer-shell electron is present in d subshell, then the elements are present in d area of periodic table. If the outer-shell electron is present in f subshell, then the elements are present in f area of periodic table.
Distinguishing electron is the one that is the last electron added to the electronic configuration of an element when the electron subshells are filled in the order of increasing energy. This distinguishing electron determines the area of the element in the periodic table. This is because this only causes the element electronic configuration to differ from other elements.

Location of the element copper in terms of s area, p area, d area, or f area has to be specified.
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.

- Under ordinary conditions, only a few pure elements occur as liquids. Give an example of a metallic and a nonmetallic element that ordinarily occur as liquids.arrow_forwardSpecify the location of each of the following elements in the periodic table in terms of s area, p area, d area, or f area. a. Aluminum b. Potassium c. Sulfur d. Goldarrow_forwardOne of the best indications of a useful theory is that it raises more questions for further experimentation than it originally answered. Does this apply to Daltons atomic theory? Give examples.arrow_forward
- 2.85 Describe how the saying “opposites attract” corresponds with the mathematical representation of Coulomb’s law shown in Equation 2.1. Remember that attractive forces have negative values and repulsive forces have positive values.arrow_forwardIs 1s22s22p6 the symbol for a macroscopic property or a microscopic property of an element? Explain your answer.arrow_forwardCertain elements have special affinities for other elements. This causes them to bind together in special ways to form .arrow_forward
- What is the electron configuration of Mg2+? How does its reactivity compare with neutral Mg? How do the reactivities of F- and F compare?arrow_forwardList five nonmetallic elements that exist as gaseous substances under ordinary conditions. Do any metallic elements ordinarily occur as gases?arrow_forwardWe have seen that the reactivity of an element is determined by its electron configuration. What is the electron configuration of the ion Cl-? (Hint: You must add one additional electron beyond the number of electrons that chlorine would normally have.) How does its reactivity compare with neutral Cl? How would the reactivities of Na and Na+ compare?arrow_forward

This is a horizontal arrangement of elements in the periodic table. b. Element 11 begins this arrangement in the periodic table. c. The element nitrogen is the first member of this arrangement. d. Elements 9, 17, 35 and 53 belong to this arrangement.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_forwardThe brilliance with which magnesium burns makes it ideal for use in marine flares and fireworks. Compare the mass of magnesium that burns with the mass of magnesium in the magnesium oxide ash that forms. Explain this in terms of atomic theory. The white light in fireworks can result from burning magnesium.arrow_forward
