QUESTION:
For the following atoms, give the number of protons, neutrons, and electrons: (3.3)a.Cdb. Tcc. Aud. Rne. Xe
ANSWER:Solution 99AQPStep 1 of 2:Here, we are asked to find the number of protons, neutrons, and electrons for the given atoms. The mass number is the sum of the total number of protons and neutrons in the nucleus of an atom of the element. The mass number is different for each different isotope of an element and is a unique identification of an element. The difference between the mass number and the atomic number gives the number of neutrons. The Atomic number is the number of protons in the nucleus of an atom. Atomic number is the unique identification of an element. In a neutral atom, the number of protons is equal to the number of electrons. Here, we are given isotopes. Isotopes are the atoms that have the same atomic number but different mass number. That is the same number of protons but a different number of neutrons. Because there are a different number of neutrons, atoms exhibit different physical properties. We represent isotopes as : or X-AWhere ‘A’ represents mass number ‘Z’ represents Atomic number ‘X’ represents the chemical element.________________
