Ionic Bonds Ionic bonding is a type of chemical bonding that involves the electrostatic attraction between oppositely charged atoms. An ionic bond is like a magnet. To form an ionic bond you need a positively charged atom and a negatively charged atom. It is not possible for a charge to be completely ionic. An ionic charge is considered ionic bond when there is more electronegativity than positivity. Ionic compounds are typically not a solid and they have a relatively high melting point. You may wonder if it is possible to create a full ionic bond. The answer is no. This is because ions contain some covalent structure. It isn’t physically possible to have a full ionic structure, it has to contain some covalent elements.

There are two main chemical bonds. Covalent bonding, the stronger of the two, is when two atoms share a pair of valence electrons, the outermost layer of the atom. These bonds are created when the two electrons have similar electronegativity. When two atoms are near each other, two similar electrons feel some attraction to the proton in the corresponding nucleus of the other atom. These attractions pull the electrons so close together, that once close enough, they become shared, creating a single bond. You might think, if this creates a single bond, can there be a double bond and beyond creating more than two electrons being shared? The answer is yes. There can also even be triple bonds. You may also think, what is the purpose of atoms coming together? This is because bonded atoms have a lower energy and are therefore more stable.

● melting point is low ● melting point is relatively high ● two components don’t share ● two components share electrons electrons ● more electronegativity ● more electropositivity ● polarity is high ● polarity is low ● occurs between one metal and ● occurs between two non- metals one non-metals ● could be in any state in room ● normally solid in room temperature temperature

By: Donla and Hanna polarity

Chemical polarity is when the electrons being transferred are not always distributed equally. One atom may apply more force on the electron than the other. One atom may also have a bigger electronegativity, how many electrons it can attract. These differences create uneven sharing in covalent bonds.

1. Is it possible to have 2 of the same atoms and 1 totally different atom to share electrons in a covalent bond? 2. Can a covalent bond take place with only 1 electron being shared? Or is that too few?

One example of an ionic bond is table salt or NaCl. Salt is formed when sodium and chloride combine to form an ionic bond. We then use this salt on our foods and we can also put rock salt which is the same substance only less refined on icy or snowy roads to melt the snow so people can drive safely. One example of a covalent bond is water or H20. It is a covalent and more specifically a polar covalent bond since water has more electronegativity than hydrogen. So that means that the electrons move more toward the oxygen nucleus than the hydrogen nucleus. Finally we use water in many ways such as drinking it, swimming in it, and using it for washing dishes.
