What are the symbol, name, and the atomic number of the element that has 21 protons in the nuclei of its atoms? What is the mass number, the number of protons, and the number of neutrons in 13153I? What is the mass number, the number of protons, and the numb...
To determine which element has a ratio of number of protons to number of neutrons equal to 1:1, we will analyze the given options step by step.Step 1: Understand the Definitions - Number of Protons (p): This is
Because protons are units of matter, atomic numbers are always whole numbers. At present, they range from 1 (the atomic number of hydrogen) to 118 (the number of the heaviest known element). As more elements are discovered, the maximum number will go higher. Theoretically, there is no maxi...
How many protons does boron have? What is the mass number of phosphorus? What element has a mass number of 14? What element has a mass number of 65? What is the atomic mass of californium? What is the mass number for dysprosium?
Isotopes are two or more forms of an element. Isotopes differ from each other according to their mass number. The number written to the right of the element's name is the mass number. The mass number represents the number of protons plus neutrons in the nucleus of an atom of the element...
Isotopes are two or more forms of an element. Isotopes differ from each other according to their mass number. The number written to the right of the element's name is the mass number. The mass number represents the number of protons plus neutrons in the nucleus of an atom of the element...
Recall now that the electrons of elements with increasing atomic number (the number of protons in the nucleus and, therefore, the number of orbital electrons in a normal, un-ionized, atom) occupy the states with lowest energy. The lower energy states are, in general, the quantum states with...
Atomic number Z represents the number of protons per atom. Mass number Z + N is equal to the number of protons Z plus the number of neutrons N present in the nuclei. Mass numbers of the most abundant isotopes are given in order of decreasing abundance. For example, Cadmium Cd-48 mass ...
and this number also tells you how many electrons are present in a neutral atom. Therefore, iron -- with an atomic number of 26 -- has 26 protons and electrons. The number of neutrons, however, can vary. Iron has four stable isotopes, and each one has a different number of neutrons....
Aluminum has an atomic number of 13, which means that each atom has 13 protons. Its atomic mass is 26.98, so each atom includes 14 neutrons, as the...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your ...
