A covalent bond is a chemical bond between two nonmetals (two metals cannot covalently bond) in which electrons are shared, while an ionic bond is a chemical bond between a me â¦ tal and a non metal due to the attraction between oppositely charged ions.
Ten syllables to each line. These syllables are broken up into five pairs - this is the pentameter. The 'rhythm' of these syllables is the iambic part. Iambic just means that the first syllable is unstressed whilst the second syllable is stressed therefore the pattern is unstressed, stressed (five times). You may find that a lot of lines start with a stressed syllable (stress, unstress is a trochee) which is used for a stronger effect.
