Lithium number of neutrons and electrons
Web3 jul. 2024 · An ion with more protons than electrons carries a net positive charge and is called a cation. An ion with more electrons than protons carries a net negative charge and is called an anion. The number of neutrons doesn't come into play since they are electrically neutral. Changing the number of neutrons determines the isotope. We know that the atomic number of lithium is 3 and the atomic mass number is about 7. Neutron = 7 – 3 = 4. Therefore, a lithium atom has four neutrons. Based on the atomic number, mass number, and neutron number of the element, three things can be considered. These are isotope, isobar, and … Meer weergeven 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 … Meer weergeven Atoms that have the same number of protons but different mass numbers are called isotopes of each other.
