If an element has 80 protons and 200.56 mass number, then the number of neutrons will be _________. Which element has 32 protons in its nucleus? What is the atomic mass of an atom that has 6 protons, 6 neutrons,
How many neutrons and electrons does a neutral atom of this element have and what is its mass number? What are the symbol, name, and the atomic number of the element that has 21 protons in the nuclei of its atoms? If an element has 12 proto...
The atomic number is shown above the element’s symbol on the periodic table. The number represents how many protons and neutrons it has. In this element, the number is 10, which means there’s 10 protons and neutrons. The atomic mass tells us the mass of the atom, for neon the mass...
This radial element corresponds to the metric of a hypersphere of radius rH that expands towards a constant event horizon rΛ. In this limit, the FLRW metric reproduces the static de-Sitter metric: 2Φ=−r2HΛ2, where the expansion becomes static (see also [10] and the Appendix here)...
Theneutron isslightlyheavierthan theproton. This increases the mass of nuclei with more neutrons than protons relative to the atomic mass unit scale based on12C with equal numbers of protons and neutrons. Thenuclear binding energyvaries between nuclei. A nucleus with greater binding energy has lower...

An atom is the smallest possible unit of matter. An atom is composed of three subatomic particles: electrons, protons, and neutrons. Neutrons are negatively charged particles and are arranged in the various shells of an atom.Answer and Explanation: ...
What element has 74 protons, a mass number of 182, and a +5 charge? State the number of neutrons and electrons. Given that most of the elements on the periodic table don't show up in living cells to any significant degree, where on Earth are they found? P...
The notation shows two numbers: the atomic number and the mass number. The given element has an atomic number equal to 11 and a mass number equal to...Become a member and unlock all Study Answers Start today. Try it now Create an account As...
