Explain a covalent bond

A covalent bond is a bond formed between two nonmetals

100

Explain an Ionic Bond

An Ionic bond is a bond between a non-metal and a metal.

100

Explain a Metallic Bond

An Ionic bond is a bond between two metals.

How to you write the formula in terms of a cation and anion?

The POSITIVE cation always goes first and the NEGATIVE anion always goes second.

200

What are some characteristics of a covalent bond?

Low melting and boiling point,various colors,poor conductivity of heat and electricity,brittle solids

200

What are some characteristics of an Ionic bond?

High melting and boiling points, a crystal like structure,solids do not conduct and are not good conductors.

200

What are some characteristics of a Metallic bond?

They have a shiny luster look, they are malleable, and are good conductors of heat and electricity.

How would you compare and contrast writing an ionic formula to naming an ionic formula?

When writing ionic formulas there are a few rules, you need to put the cation first and anion second, when the two charges don't cancel out, you must change the subscripts, you must use parentheses to indicate the group with polyatomic atoms,etc. When naming Ionic formulas you use binary/molecular system.

Explain the rules needed to be a covalent bond.

Some rules is that it needs to be between two non-metals and two atoms must be sharing electrons.

300

Explain the rules needed to be an Ionic bond.

Some rules are that it needs to be a metal and a non-metal and two or more atoms loss or gain electrons to form an ion.

300

Explain the rules needed to be a Metallic bond.

Some rules are that it needs to be between two metals and it needs to create atoms "clumped" together.

How do you name an Ionic Compound?

When naming ionic compounds you first name the metal by its element name and then name the nonmetal by its element name and add an -ide ending.

Analyze the following elements and explain why it would not be considered a covalent bond and what must be different for it to be a covalent bond?   CuO   

It is an Ionic bond because it is between a non-metal AND a metal. For it to be a covalent bond it would have to swap out Copper for a non-metal.

400

Analyze the following elements and explain why it would not be considered a Ionic bond and what must be different for it to be a Ionic bond?  NiZn

It is a Metallic bond because it is between two nonmetals. For it to be an Ionic bond it would have to be a metal and a non-metal.

400

Analyze the following elements and explain why it would not be considered a Metallic bond and what must be different for it to be a Metallic bond? NiO

It is an Ionic bond because it is between a metal and a nonmetals. For it to be a Metallic bond it would have to be between two nonmetals.

400

Why do you think it is important to name ionic compounds accurately?

It makes it easier to share information about the compound including its properties.

500

Decide which of the following bonds would be considered a covalent bond and why.                      NiF, MgCa,FCl,PZn

The covalent bond would be FCl because it is two non-metals and the rest of the choices is either between a non-metal and a metal or two metals.

500

Decide which of the following bonds would be considered an Ionic bond and why.                             CuNi, NaMg, BrO, FeO  

The Ionic bond would be FeO because it is between a metal and nonmetal and the rest of the choices is either between two nonmetals or two metals.

500

Decide which of the following bonds would be considered an Metallic bond and why.                       NiZn, BO, BeAs, SSe

The Metallic bond would be NiZn because it is between two metals and the rest of the choices is either between two nonmetals or a non-metal and metal.

How would you write the following Ionic Compound.     K+1 and ClO4-1

KClO4
