Concept introduction;
Atomic number (Z):
Atomic number of an element is the number of protons found in the nucleus of every atom of that element.
Mass number (A):
Mass number of an element is defined as the total number of protons and neutrons in an atom.
Protons:
A proton is one of three main particles that make up the atom. Protons are a tiny, dense region at the center of the atom. Protons have a positive electrical charge of
Neutrons:
Atoms of all elements except for most atoms of hydrogen have neutrons in their nucleus. Unlike protons and electrons, which are electrically charged, neutrons have no charge they are electrically neutral.
Electrons:
Electrons have an electric charge of

- What are the different kinds of particles in the atoms nucleus? Compare their properties with each other and with those of an electron.arrow_forwardDefine mass number. What is the difference between mass number and atomic mass?arrow_forwardCarbon A carbon atom has a mass number of 12 and an atomic number of 6. How many neutrons does it have?arrow_forward
- Give the atomic number (Z) and the mass number (A) for each of the following: a. a carbon atom with 8 neutrons b. an aluminum atom with 14 neutrons c. an argon atom with 20 neutrons d. a copper atom with 36 neutronsarrow_forwardXenon An isotope of xenon has an atomic number of 54 and contains 77 neutrons. What is the xenon isotope’s mass number?arrow_forwardThough the common isotope of aluminum has a mass number of 27, isotopes of aluminum have been isolated (or prepared in nuclear reactors) with mass numbers of 24, 25, 26, 28, 29, and 30. How many neutrons are present in each of these isotopes? Why are they all considered aluminum atoms, even though they differ greatly in mass? Write the atomic symbol for each isotope.arrow_forward
- 1. The mass of an atom of manganese is 54.9380 u. How many neutrons are contained in one atom of this element? 25 29 30 55arrow_forwardWhy do we not necessarily expect the number of neutrons in the nucleus of an atom to be the same as the number of protons?arrow_forwardWhile traveling to a distant universe, you discover the hypothetical element X. You obtain a representative sample of the element and discover that it is made up of two isotopes, X-23 and X-25. To help your science team calculate the atomic weight of the substance, you send the following drawing of your sample with your report. In the report, you also inform the science team that the brown atoms are X-23, which have an isotopic mass of 23.02 amu, and the green atoms are X-25, which have an isotopic mass of 25.147 amu. What is the atomic weight of element X?arrow_forward
