water is made of one oxygen atom covalently bonded to two hydrogen atoms. the resulting water molecule is polar, or has an uneven distribution of electrons. this means that part of the water molecule is slightly negatively charged (δ-), and another part is slightly positively charged (δ+). the models show the chemical structure of water. complete the paragraph to explain why water is a polar molecule. in a molecule of water, the oxygen atom shares with each hydrogen atom. oxygen also has nonbonding pairs of valence electrons. because valence electrons are more attracted to oxygens nucleus than to hydrogens nucleus, the oxygen atom has a slightly charge and the hydrogen atoms have a slightly charge.
Answer
Answer:
- electrons
- two
- negative
- positive
Explanation:
Step1: Covalent - bond nature
In a water molecule, oxygen and hydrogen form covalent bonds by sharing electrons.
Step2: Non - bonding electrons
Oxygen has 6 valence electrons. After sharing 2 electrons (one with each hydrogen), it has 2 non - bonding pairs of valence electrons.
Step3: Electronegativity difference
Oxygen is more electronegative than hydrogen. So, valence electrons are more attracted to oxygen's nucleus, giving oxygen a slightly negative charge.
Step4: Charge distribution
Since electrons are pulled towards oxygen, hydrogen atoms have a slightly positive charge due to the unequal sharing of electrons.
