An atom of platinum has a mass number of 195 and contains 74 electrons. All Rights Reserved. Chemistry End of Chapter Exercises In what way are isotopes of a given element always different? Information about the naturally occurring isotopes of elements with atomic numbers 1 through 10 is given in Table 3. Protons, neutrons, electrons? The average atomic masses of some elements may vary, depending upon the sources of their ores.
Atoms are electrically neutral if they contain the same number of positively charged protons and negatively charged electrons. For example, magnesium exists as a mixture of three isotopes, each with an atomic number of 12 and with mass numbers of 24, 25, and 26, respectively.
One method of writing the formula for an isotope shows the element name or symbol followed by the mass number, as helium-4 or He-4.
Hydrogen-2, symbolized 2 H, is also called deuterium and sometimes symbolized D. Therefore, chlorine consists of 75.How to find the number of protons, neutrons, and electrons from the periodic table

References Boise State University: Consider chlorine, a yellowish gas, or lead, a gray-black solid, or mercury, a silvery liquid. Determine the numbers of protons, neutrons, and electrons in one of these iodine anions. If the gas is comprised of a single element, what would that element be?
Mass spectrometry MS is widely used in chemistry, forensics, medicine, environmental science, and many other fields to analyze and help identify the substances in a sample of material. Since its initial use during the development of modern atomic theory, MS has evolved to become a powerful tool for chemical analysis in a wide range of applications.
Open the Build an Atom simulation Drag protons, neutrons, and electrons onto the atom template to make a neutral atom of Lithium-6 and give the isotope symbol for this atom.
Best Answer: If the mass number of an isotope is known, the actual number of neutrons can be calculated. The atomic number on the Periodic Table identifies the number of protons in any atom of that element.
Three main particles form every atom. From that, we can figure out the number of electrons.
