D Question 3 2 pts The greater the energy of an electron, O the larger it is O the closer it orbits to the nucleus O the farther it orbits from the nucleus O the more lively it is to be transferred rather than shared. O the greater the number of other electrons that can share its orbital D Question 4 2 pts Which element is least common in living organisms? carbon O hydrogen nitrogen axygen sodium Question 5 2 pts Regions of partial negative charge in polar covalent bonds are found near O the more electronegative atom the atom with more potrs O the atom with a larger atomic mass. O the atom with electrons in higher energy levels O the atom that loses more electrons

Explanation / Answer

Q3. The farther its orbit from the nucleus.

the more electrons shelding an electrons has , the lower the Zeff value. thus the lower the zeff value, the less attracted the electron is to the nucleus so it is not hold the tightly by the nucleus

Q4. Sulpher is least common in living organisims than hydrogen, carbon , oxygen and nitogen. becauses is commomly found in all elements of living organisims.

Q5. the more electronegative atom. -A polar covelent bond is that shown below of double bond between carbon and oxygen . since oxygen is more electeonegitive than carbon , the electrons will spend more time around the oxygen atom.
