WebAn element has 5 protons, 6 neutrons, and 5 electrons. What is the mass number? Medium Solution Verified by Toppr The mass number of an element is the sum of the protons and neutrons. WebFor example, most carbon (≈ 99 %) has 6 protons and 6 neutrons and is written as 12C to reflect its atomic mass. However, about 1 % of the carbon in the Earth’s biosphere has 6 protons and 7 neutrons (13C) forming the heavy stable isotope of this important element. Stable isotopes do not decay into other elements. do it directed WebThe number of neutrons for a given element is the only number that can change and still have the identity of the element stay the same, (because the atomic number is the … WebFor most elements other than hydrogen, isotopes are named for their mass number. For example, carbon atoms with the usual 6 neutrons have a mass number of 12 (6 … contact center omnichannel platforms WebJan 17, 2024 · The number of protons determines an element’s atomic number (Z) and distinguishes one element from another. For example, carbon’s atomic number (Z) is 6 because it has 6 protons. The number of neutrons can vary to produce isotopes, which are atoms of the same element that have different numbers of neutrons. WebJan 25, 2024 · Solution: a. The atomic number is equal to the number of protons in one atom. Since the atom contains \ (8\) protons, the atomic number is \ (8.\) b. This atom contains an equal number of protons and neutrons, so it has no overall charge. Example3. Helium atom has an atomic mass of \ (4\,\rm {u}\) and two protons in the … do it easy painting services WebDec 7, 2015 · Every carbon atom has six protons, and the majority of carbon atoms have six neutrons. A carbon-12 atom has 6 protons (6P) and 6 neutrons (6N). But some types of carbon have more than six neutrons. We call forms of elements that have a different number of neutrons, isotopes.
