Sugar or Salt? Ionic and Covalent Bonds - Union University
uu.eduthe other hand, is composed of carbon, oxygen, and hydrogen and has covalent bonds. D Introduction A salt molecule is made up of one sodium atom and one chlorine atom. For salt to be made, the sodium atom must lose an electron and become a sodium ion. When sodium loses an electron it becomes a Na+ and is called a cation. Na → Na+ + e-

mchem.weebly.comBond enthalpy is the enthalpy change to break one mole of covalent bonds in the gas phase. For most bonds (e.g. C -H, C C, C=O, O H, etc.) the value for the bond enthalpy is an average taken from a range of molecules as the exact value varies from compound to compound. For some bond enthalpies (e.g.

Covalent Bonding - Save My Exams
cdn.savemyexams.co.ukOxygen atoms form both covalent and ionic bonds. (a) Water is formed when two atoms of hydrogen combine with one atom of oxygen. (i) Draw a dot and cross diagram of a molecule of water. You need only show the electrons in the outer shells. (2) (ii) Explain how the covalent bonds in the water molecule hold the hydrogen and oxygen atoms together. (2)
CHAPTER 14 COVALENT BONDING: ORBITALS

The two C‒Cl σ bonds are formed from overlap of sp2 hybrids from C with sp3 hybrid orbitals from Cl. The double bond between the carbon and
