How does chemical bonding affect solubility? Which of the forces of molecular attraction is the weakest: hydrogen bond, dipole interaction, The number of non-bonding electrons is almost always a multiple of two, and it is usually much clearer and easier to check when drawing a structure to arrange the non-bonding electrons in pairs, to match the pairs of electrons in the covalent bonds.

Some molecules contain a double bond , which consists of two shared pairs of electrons. For example, oxygen molecules consist of two oxygen atoms joined together. Oxygen atoms can form two covalent bonds, so to link the two oxygen atoms together, a double bond forms between them. Nitrogen molecules consist of two nitrogen atoms joined together.

Nitrogen atoms can form three covalent bonds, so a triple bond forms between them. Drawing structures Instead of trying to remember lots of different dot and cross diagrams, it may help to understand how to draw them using given information.

How many bonds? Group Example Electrons Covalent bonds 4 Carbon, C 4 4 5 Nitrogen, N 5 3 6 Oxygen, O 6 2 7 Chlorine, Cl 7 1 Note: Hydrogen atoms only have one electron and form one covalent bond as they only need one more electron for a full outer shell. How many circles? This incomplete dot and cross diagram shows only the bonding pairs of electrons Finally add in the non-bonding outer electrons.

How many covalent bonds would a tellurium atom make? Predict the formula of a compound between tellurium and hydrogen. Tin atoms make covalent bonds. How many covalent bonds would a tin atom make?

Predict the formula of a compound between tin and hydrogen. It is in the halogen group on the periodic table. How many covalent bonds would an atom of this element form? There have been reports that atoms of element Lv were made by smashing smaller atoms together.

Using the periodic table, determine what column element would be in and suggest how many covalent bonds an atom of this element would form. A covalent bond is formed when two atoms share electrons. Electron sharing joins two atoms in a covalent bond. This is a more stable arrangement than 2 individual atoms. Hydrogen atoms form only one covalent bond because they have only one valence electron to pair. Oxygen atoms form 2 covalent bonds because oxygen atoms have 6 valence electrons 2 lone pairs plus 2 unpaired electrons that are shared to achieve octet.

Learning Objectives To describe how a covalent bond forms. To apply the octet rule to covalent compounds. Electron Sharing Previously, we discussed ionic bonding where electrons can be transferred from one atom to another so that both atoms have an energy-stable outer electron shell. Covalent Bonds between Different Atoms Now that we have looked at electron sharing between atoms of the same element, let us look at covalent bond formation between atoms of different elements.

Covalent Bonds in Larger Molecules The formation of a water molecule from two hydrogen atoms and an oxygen atom can be illustrated using Lewis dot symbols shown below.

Solution Yes. Concept Review Exercises How is a covalent bond formed between two atoms? How does covalent bonding allow atoms in group 6A to satisfy the octet rule? Answers Covalent bonds are formed by two atoms sharing electrons. Key Takeaways A covalent bond is formed between two atoms by sharing electrons. The number of bonds an element forms in a covalent compound is determined by the number of electrons it needs to reach octet. Hydrogen is an exception to the octet rule.
