Chemical Bond Research Paper
Mariel Beauroyre
9-B
A chemical bond is form with the joining of two or more atoms (when two atoms are joined they form molecules and compounds.)
Which are being held together by the attraction (force attraction) of atoms through sharing as well as exchanging electrons.
Chemical bonds are found in molecules, crystals, or in solid metals. They also organized the atoms in order structures.
But why are they important you may ask?
They’re important because every material or substance in the world depends on chemical bonds for it to be made. Chemical bonds are everywhere in our water, salt, air, plants, synthetic materials and many more.
Take for example table salt. Salt is made out of sodium (Na) and of chlorine (Ci) NaCi. Sodium is a hard

The transfer of electrons (either gain or lost) of this two elements produce CaCi . Which has several uses, highway maintenance when there is ice and snow, and even medicine for people with low levels of calcium in their blood.
Covalent bond: (electrons shared between atoms)
Covalent Bond in were one or more pairs of electrons are shared by two atoms. This type of bond occurs with non-metal atoms that share electrons. The only electrons involved are the ones found in the outer energy level of an atom. These electrons are also called valence electrons. The sharing of electrons occurs because the atom wants to have a full shell and become a stable atom.
There are two types of covalent bonds:
Polar Covalent: two atoms that have different electronegativity causing the separation of charges.
Non-polar: when the two atoms have identical or similar electro negativities so the charges are distributed equally.
A covalent compound: it is a molecule formed by covalent bonds in which atoms share one or more pairs of valence electrons.
Properties of Covalent compounds:
• Hard
• Good insulators
• Transparent
• Poor conductors of heat and electricity (specially in water)
• Tend to be gases, liquids or soft
P1 Task 1
415 Words | 2 PagesCovalent bonding - Covalent bonding is when two atoms share electrons this can only occur between two non-metals. They share electrons to fill up their outer shells, this makes the atoms stable. A Covalent bond can form up to one to three Covalent bonds with non-metals depending on how much electrons they possess. They don't always share electrons

The measure of space that the molecules occupy (volume) is derived from the space in between the molecules and not the space the molecules contain themselves. 4. The motions for: • Solid- are not able to move out of their positions relative to one another, but do have small vibrational movements.

Pre-Ap Physical Science: The Importance Of Electrons
507 Words | 3 PagesDylan Clayton Mrs. Beckwith Pre-Ap Physical Science 9 7 December 2015 The Importance of Electrons Electrons are the negatively charged subatomic particles that revolve the center, nucleus, of an atom. They are arranged in different energy levels and they orbit around the nucleus like the Earth revolves around the Sun. Electrons are important in atoms, compounds, and chemical bonds involved in chemical reactions. These subatomic particles have importanance to the organization of elements into periods & groups, characteristics of elements in the same periods & groups, and the formation of compounds based on periodic table placement.

(ionically bonded- metal to nonmetal). Labelling them include pairing a metal element to a nonmetal. This will result in elements names combining together.
Chemistry 101 Chemistry
520 Words | 3 PagesMany people do not realize that chemistry is a part of our day to day lives. One specific thing we see on a daily basis is the colors and paint people use in paintings, on buildings, and any other place paint could be. When this paint is developed, the people who make it have to decide exactly what the compound should be made up of. This is an important thing to consider when making these paints because as discussed in Chemistry 101 lab, compounds are different things that develop one item, in this case it is paint. They have to make sure that the paint is homogenous because if it was heterogeneous when being applied, the paint would not go on well.

In order to accurately digest the experiments results, research of definitions of each relating led to the following information: ionic compounds are positive and negatively charged ions that experience attraction to each other and pull together in a cluster of ionic bonds; they are the strongest compound, are separated in high temperatures, and can be separated by polar water molecules. A covalent compound forms when two or more nonmetal atoms share valence electrons; covalent compounds are also
