An atom of oxygen has 8 protons and 10 electrons, this means the atom is ____
|
|
positively charged because it has excess electrons
|
|
|
negatively charged because it has excess electrons
|
|
|
positively charged because it has a deficiency of electrons
|
|
|
negatively charged because it has a deficiency of electrons

Explanation:
Detailed explanation-1: -The oxygen atom attracts electrons more strongly than do the hydrogen atoms. As a result, the end of the molecule with the oxygen atom has a slight negative charge. The end of the molecule with the hydrogen atoms has a slight positive charge. Attractions between molecules – Opposite charges attract.
Detailed explanation-2: -Atomic number is equal to number of protons i.e. 8. Since number of protons is equal to number of electrons i.e. 8, therefore charge on the atom is 0.
Detailed explanation-3: -Answer: An oxygen ion has 8 protons and 10 electrons. The number of protons tells us the identity of the element because the number of protons is the same as the atomic number.
