Chapter 2, Problem 54P
Interpretation Introduction

(a)

Interpretation:

True and false

Elements in the same column of the periodic table have the same-outer shell electron configuration.

Concept Introduction:

The periodic table of an element is the chemical element’s tabular arrangement structured according to their electronic configuration, chemical properties and atomic number. Usually in one period or row towards the left elements are metal and non-metal towards the right having the elements with same chemical properties are kept in the same column. Table column are known as groups and table rows are known as periods.

Interpretation Introduction

(b)

Interpretation:

True and false

All group 1A elements have one electron in their valence shell.

vi. Answer true or false. (a) Elements in the same column of the Periodic Table have the same outer-shell electron configuration. (b) All Group 1A elements have one electron in their valence shell. (c) All Group 6A elements have six electrons in their valence shell. (d) All Group 8A elements have eight electrons in their valence shell. (e) Period 1 of the Periodic Table has one element, period 2 has two elements, period 3 has three elements, and so forth. (1) Period 2 results from filling the 2s and 2p orbitals and, therefore, there are eight elements in period 2. (g) Period 3 results from filling the 3s, 3p, and 3d orbitals and, therefore, there are nine elements in period 3. (h) The main-group elements are s block and p block elements.

In theory, there are an infinite number of energy levels and atomic orbital types that we can define using the solutions to the Schrödinger…
v. Answer true or false. (a) Mendeleev discovered that, when elements are arranged in order of increasing atomic weight, certain sets of properties recur periodically. (b) Main-group elements are those in the columns 3A to 8A of the Periodic Table. (e) Nonmetals are found at the top of the Periodic Table, metalloids in the middle, and metals at the bottom. (d) Among the 116 known elements, there are approximately equal numbers of metals and nonmetals. (e) A horizontal row in the Periodic Table is called a group. () The Group 1A elements are called the "alkali metals." (g) The alkali metals react with water to give hydrogen gas and a metal hydroxide, MOH, where “M" is the metal. (h) The halogens are Group 7A elements. (1) The boiling points of noble gases (Group 8A elements) increase in going from top to bottom of the column.
