Isotope: An atomic form of an element having a particular number of neutrons. Different isotopes of an element have the same number of protons but different numbers of neutrons and hence different atomic masses, e.g. U-235, U-238. Some isotopes are unstable and decay (qv) to form isotopes of other elements. TOP The mass number, the superscript next to the symbol, is the sum of the number of protons and neutrons in the nucleus of this particular isotope. In this case, the mass number is 12, which means that the number of neutrons in the atom is 12 − 6 = 6 (that is, the mass number of the atom minus the number of protons in the nucleus equals the ...
16. The most stable nuclides possess 1) fewer neutrons than protons; 2) even numbers of neutrons and protons; 3) twice as many protons as neutrons; 4) an odd number of protons and neutrons. ANS: 2 17. If the radioactive atom, 92U239 emits an alpha particle, the atom remaining is

9 traits of critical thinking

For example, all radon isotopes have 86 protons (Z=86), but radon-222 has 136 neutrons (86 + 136 = 222), whereas radon- 220 has only 134 neutrons (86 + 134 = 220). The chemical symbol for radon is Rn, and the mass number is usually placed either after the symbol (Rn-222) or to the left and above it (222Rn).

Problems with this model: • Uncertainty principle => nucleus would have too much energy • Predicts incorrect spin for nuclei Rutherford suggested a new elementary particle in the nucleus, with roughly the same mass as the proton, and zero charge. I.e., the “neutron”.

Atoms consist of protons, neutrons and electrons. The nucleus contains protons and neutrons; together these are called nucleons. Protons are positively (+) charged particles. Neutrons are electrically neutral and have no electrical (0) charge. Protons and neutrons are about 1800 times as heavy as an electron, which orbits the nucleus as a cloud.
