Neon is a non-metallicelement, so it lies on the right-hand side of the modern periodic table. The neon element symbol is Ne. It has the atomic number 10. So, in the neon atom, the number of protons and electrons is 10 each. Themass numberof neon is 20 amu. So, the number of ...
Boron-10 Boron-11 Boron-9 Boron-13 Which version of Boron does not need the dash, and why? What are the names of the elements/isotopes below? Protons = light spheres and neutrons = dark ones How many electrons can each energy shell hold? Draw a Bohr model for the following...
In physics, a fundamental element often refers to basic constituents of matter like electrons, protons, and neutrons, or to essential principles like force and energy. 12 What determines the unit used in a specific scientific measurement? The unit used in scientific measurements is determined by th...
Anelementis a substance that cannot be separated into simpler substances by chemical means. An element consists of anatomwith a unique combination ofprotons,neutrons, andelectrons. For example, the element hydrogen has one proton, one neutron, and one electron. We cannot use chemical methods to ...
also called the inert gases, did not react with anything. However, the element fluorine is so highly reactive that it actually can react with these elements. An elements reactivity is highly dependent on its natural stability created by the number of protons, neutrons, and electrons in each ato...
