It's Metallic Bonding because it's formed when the valence electrons in a metal and the ions of the metals are bonding. The metals can be find on the left of the line in the periodic table.

# data[].attributes.body
The compound that has a covalent bond is H2O because both of the elements are non- metals.

# data[].attributes.attachment_caption
This is an example of what an ionic bond does. Ionic bonds transfer their valence electrons from a metal to create 8 valence electrons for the non-metal. 

# data[].attributes.body
In our case K (Potassium ) is the metal and it transfers the valence electrons to help Cl (Chlorine) create 8 valence electrons.

# data[].attributes.body
The correct answer is C because potassium is a metallic element and chloride is a non-metallic element. Therefore, it is an ionic bond when combined. In an ionic bond, metal elements transfer or give up electrons to non-metal elements.

option a
Cl2
there are 2 chlorines atoms and they have the same electronegativity. difference between them is 0. hence, it is non polar molecule. because they have linear structure are identical.

In an Ionic bond the non metal asks the metal for some valence electrons to give them 8 so they can have stability and the metal gives the valence electrons.

Li (Lithium) is a metal and we need to find a non-metal so we can give them our electrons the non-metal we decided to give electrons to was Br (Bromine) because it is a non-metal and creates a ionic bond.

Water is polar (H2O), then hexane should be non-polar because they do not form a solution.

Gold Is an element located on the periodic table in the group of metals(on the far left side of the periodic table). Malleability is a property of gold because gold is a metal and metals carry the characteristics or properties of being malleable and ductile. Its also because metals have free flowing electrons which make the metal more bendable

# data[].attributes.body
Answer: A because it is symmetrical which makes it a non-polar molecule and the electronegativity difference is 0 which makes it a non polar covalent bond.

K
2-8-8-1
Cl
2-8-7
K would give Cl it's 1 valence electron so Cl can have 8.

For this question you need to know the properties of metallic bonds.
They conduct heat and electricity very well. Because electrons flow free.

# data[].attributes.body
A solid is an excellent conductor of electricity  because of free flowing electrons. With electrons moving around freely, an atom has to ability to perform many thing, such as conduct electricity.

A) Sulfur B) Copper C) Fluorine D) Carbon

# data[].attributes.body
Answer: B
To answer this question, we need to know that metallic bonding consists of 2 metal elements. As shown in the periodic table, Sulfur(S), Fluorine(F) and Carbon(C) were all nonmetals, therefore only Copper (Cu) is left. Copper is also a metal as you can see in the image above.

Just like Tia and Tamera metallic bonds are like twins but different...

# data[].attributes.body
Metallic bonds occurs between two metallic elements it can't occur with a non-metal and a metal or a non-metal and non-metal. An example of a metallic bond is K (Potassium) and Li (Lithium) these are both metallic.

When potassium chloride forms potassium transfers its electrons to chloride so chloride would be able to obtain a perfect 8.

This image shows hydrogen is positive and bonds with chloride ion. 

# data[].attributes.body
In an aqueous solution, a chloride ion attracts the hydrogen end. It is a positive pole because a chloride ion is negative. (Keep in mind) Hydrogen is a positive ion, Oxygen is a negative ion.

When we talk about Polar bonds we look at an element's electronegativity. We have to look at all the possible answers and find the electronegativity once we find it we find the difference. Polar bonds range from 0.5-1.6 and out of the answers HI is 0.5 while HF is 1.8, HCI is 1, and HBr is 0.8 and that makes HI the least polar.

# data[].attributes.body
BaO is Barium Oxide. The bond this forms is a ionic bond. An ionic bond is formed when a metallic element gives electrons to nonmetallic element. Which also means valence electrons are being transferred.

You can find the electonegativity by looking on table s

Unlike the other options, Hydrogen Iodine(HI) has the smallest electronegativity out of the four answers

Nitrogen forms a covalent bond and share 3 electrons from each side. To total 6 electrons to share between 2 nitrogen atoms. For their to be covalent bonding so it could share electrons.

# data[].attributes.body
Answer: A
The answer for question 18 is A. To solve this problem, we need to calculate each of the molecules to find out which one is the least polar. The electronegativity varies from polar, non-polar to ionic bond. Anything less than or equal to 0.4 will be considered non-polar. Any difference above 0.4 to 1.7 will be considered polar, and anything above 1.7 would be an ionic bond. You can find out by subtracting the 2 electronegativities of each bond. (You can find the electronegativity in Table S). That would make HI the least polar bond because it has an electronegativity of 0.5, while the others had a bigger difference of electronegativity. HF has a difference of 1.8, HCl has 1, and HBr has 0.8. (Note: Subtract the bigger electronegativity to the smaller one)

CaCl2 has the highest melting point. That is because this compound is the bond of a non-metal and a metal, meaning that this is an Ionic bond, and Ionic bonds have high melting points. Ionic bonds have equal amounts of positive and negative ions, and the opposite charges have a Strong force between eachother, which gives Ionic compounds high melting points.

# data[].attributes.body
To answer the question, we need to know that ionic compounds form when metals and non-metals combine. Since the metal element (Lithium) is already provided for us, we'll just have to find the nonmetal element to make up the ionic compound. The answer is D (Br) because it's a nonmetal element (as you can see in the periodic table) and forms an ionic compound with Lithium. The other 3 elements, (K, Fe, and Kr) were all metallic elements.
