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.

Table column are known as groups and table rows are known as periods.

Interpretation Introduction

(c)

Interpretation:

True and false

All group 6A elements have eight electrons in their valence shell.

Interpretation Introduction

(e)

Interpretation:

True and false

In the periodic table, Period 1 has one element, Period 2 has two elements, Period 3 has three elements and so forth.

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

(f)

Interpretation:

True and false

Period 2 results from filling the 2s an 2p orbitals and therefore, there are eight elements in period 2.

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

(g)

Interpretation:

True and false

Period 3 results from filling the 3s, 3p and 3d orbitals, and therefore, there are nine elements in Period 3.

Concept Introduction:

Table column are known as groups and table rows are known as periods.

Interpretation Introduction

(h)

Interpretation:

True and false

The main group elements are s block and p block elements.
