Cation</em>
When naming a chemical compound, <u>the cation</u> is written first before anything else.
A typical ionic compound consists of two components - the cation and the anion. While the <u>cation is positively charged in ion</u>, <u>the anion is negatively charged. </u>The cation of a typical ionic compound is named first before the anion and the name often carries that of the element that composes it.
The name of the element that makes up the anion is modified by removing the last few characters ending the name and replacing it with the suffix 'ide'. For example, NaCl is named sodium chloride.
Let (CH2O)n be molecular formula,
(12+1+1+16)n=90.08
30n=90.08
n=3
molecular formula: (CH2O) 3= C3H6O3
1 mole contains 6.02 * 10^23 molecules
0.578 moles of water contains 0.578 * 6.02 * 10^23 molecules
Band theory
The atomic orbitals of metals combine to form <em>molecular orbitals</em>. The molecular orbitals are so close in energy that they form a <em>band</em> of energies.
<em>Ionic bond theory</em> is incorrect because there are no ions in metals.
<em>Covalent bond theory</em> is incorrect because there are no covalent bonds in metals.
<em>Electron bond theory</em> is incorrect because there is no theory with that name (but there is a <em>valence bond theory</em>).
