Ionic bonds form when one atom gives up one or more electrons to another atom. These bonds can form between a pair of atoms or between molecules and are the type of bond found in salts.]]> 2018-03-05 11:24:29 UTC https://padlet.com/15jcorcoran/tq3etct543f2/wish/238014797 Covalent bonds 15jcorcoran https://padlet.com/15jcorcoran/tq3etct543f2/wish/238015199 A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.]]> 2018-03-05 11:26:12 UTC https://padlet.com/15jcorcoran/tq3etct543f2/wish/238015199 15jcorcoran https://padlet.com/15jcorcoran/tq3etct543f2/wish/238015651 Covalent bonding occurs when pairs of electrons are shared by atoms. Atoms will covalently bond with other atoms in order to gain more stability, which is gained by forming a full electron shell. By sharing their outer most (valence) electrons, atoms can fill up their outer electron shell and gain stability.]]> 2018-03-05 11:28:02 UTC https://padlet.com/15jcorcoran/tq3etct543f2/wish/238015651 Example of Ionic Bonding 15jcorcoran https://padlet.com/15jcorcoran/tq3etct543f2/wish/238016150 Table salt is an example of an ionic compound. Sodium and chlorine ions come together to form sodium chloride, or NaCl. The sodium atom in this compound loses an electron to become Na+, while the chlorine atom gains an electron to become Cl-. Together, they form a neutral compound because the ions balance each other out. This is true for all ionic compounds - the positive and negative charges must be in balance.]]> 2018-03-05 11:29:57 UTC https://padlet.com/15jcorcoran/tq3etct543f2/wish/238016150 Example of Covalent Bonding 15jcorcoran https://padlet.com/15jcorcoran/tq3etct543f2/wish/238017617 Methane molecule (CH4)
The electronic configuration of carbon is 2,4. It needs 4 more electrons in its outer shell to be like the noble gas neon. To do this one carbon atom shares four electrons with the single electrons from four hydrogen atoms. The methane molecule has four C-H single bonds.
