E 2.1 Atomic structure and the Periodic Table 2.1 Atomic structure PL All parts of this exercise will help you to use the Periodic Table to find information about the structure of the atoms of elements. You will … Bromine is the 35th element of the periodic table so its atomic number is 35. The atomic number of an element is equal to the number of protons and electrons in that element. Therefore, a bromine atom has thirty-five protons and thirty-five electrons. Meer weergeven An atom is the smallest particle of an element that has no independent existence but is directly involved in chemical … Meer weergeven Atoms that have the same number of protons but different mass numbers are called isotopes of each other. The English chemist Frederick Sodi first came up with the idea of … Meer weergeven An atomic number is a number that carries the properties of an element. The number of electrons and protons in an element is determined by the atomic number. Also, the exact position of an element is determined in … Meer weergeven When an atom carries a negative or positive charge by accepting or rejecting electrons, it is called an ion.
