WebbSolution for Determine the number of protons and the number of electrons in each ion.a. Al3 + b. Se2 - c. Ga3 +… When an atom carries a negative or positive charge by accepting or rejecting electrons, it is called an ion. The ionic properties of the elements depend on the exchange of electrons. In an atomic ion only the number of electrons changes but the number of protons and neutrons does not change. Selenium has … Visa mer An atom is the smallest particle of an element that has no independent existence but is directly involved in chemical reactions as the smallest unit. Atoms are so small particles that they cannot be seen even … Visa mer 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 isotopes in 1912, and the scientist Aston in 1919 … Visa mer 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 … Visa mer
