Answer:
Valence electrons are the outermost electrons of an atom and are normally the only electrons that participate in chemical bonding. Atoms with full valence electron shells are extremely stable and therefore do not tend to form chemical bonds and have little tendency to gain or lose electrons.
Answer:
Explanation:
Step 1: Obtain the mass of each element present in grams. Element % = mass in g = m.
Step 2: Determine the number of moles of each type of atom present. ...
Step 3: Divide the number of moles of each element by the smallest number of moles. ...
Step 4: Convert numbers to whole numbers.
Answer: A polar bond is a covalent bond between two atoms where the electrons forming the bond are unequally distributed.
Example: A water molecule, abbreviated as H2O, is an example of a polar covalent bond. The electrons are unequally shared, with the oxygen atom spending more time with electrons than the hydrogen atoms.
