Chapter 2, Problem 7MCP

(a)

Interpretation Introduction

Interpretation:

The element Magnesium is an alkali metal or an alkaline earth element has to be discussed.

(b)

Interpretation Introduction

Interpretation:

The element Magnesium is a cation former or anion former has to be discussed.

Concept Introduction:

Metals are elements that have the tendency of losing one or two electrons to gain a positive charge.

(c)

Interpretation Introduction

Interpretation:

Which sublevel is their outermost electron located in Magnesium has to be identified.

(d)

Interpretation Introduction

Interpretation:

The shorthand electronic configuration of Magnesium has to be written.

Concept Introduction:

Electron configuration means the distribution of electrons of an atom.

(e)

Interpretation Introduction

Interpretation:

Magnesium has higher or lower ionization energy than Calcium should be explained.

Concept Introduction:

Ionization energyis the minimum energy that is required to remove one electron from the valence shell of a gaseous atom.

Ionization energy increases moving from left to right across an element period.

(f)

Interpretation Introduction

Interpretation:

Magnesium has smaller or larger atom than Calcium should be explained.

(g)

Interpretation Introduction

Interpretation:

The formula of both the Magnesium and Calcium ions and reason for which one is larger has to be explained.
