What Element Has 15 Protons And 18 Electrons. Web most of the elements important in biology need eight electrons in their outermost shell in order to be stable, and this rule of thumb is known as the octet rule. The number of proton = number of electron = atomic number.
Web most of the elements important in biology need eight electrons in their outermost shell in order to be stable, and this rule of thumb is known as the octet rule. Protons have a positive electrical charge of one (1+) and a mass of about 1 atomic mass unit (1 amu). What is the name of the element? Atomic number & mass number. After adding three more electrons in the outermost orbital of the phosphorus atom , new atomic number will be 18.
