Explanation An atom is a combination of protons and electron. Protons have positive charge, and electrons have negative charge. The number of protons present in the nucleus is said to be atomic number . For a neutral atom, the atomic number is equal to the number of protons which in turn is equal to the number of electron O 2 − Here, the element is oxygen and according to the periodic table, the atomic number of oxygenis 8 . According to the explanation, for a neutral atom, the atomic number is equal to the number of proton which is equal to the number of electron. Here, the atomic number is 8 , so the number of proton is 8 and number of electron is also 8 . But the symbol shows that the oxygen ion has − 2 charge which implies that it gains two electrons more and thus as a result it has a total of 10 electron. Therefore O 2 − has 8 protons and 10 electrons. K + Here, the element is potassium and according to the periodic table, the atomic number of potassium is 19 . According to the explanation, for a neutral atom, the atomic number is equal to the number of protons which is equal to the number of electron. Here the atomic number is 19 , so the number of proton is 19 and the number of electron is also 19 . But the symbol shows that the potassium ion has + 1 charge which implies that it loses one electron and thus as a result it has a total of 18 electron. Therefore K + has 19 protons and 18 electrons I − Here, the element is iodine and according to the periodic table, the atomic number of iodine is 53
