What is a monatomic gas? How many valence electrons do the noble gases possess? Where are the noble gases on the periodic table? What is the chemical symbol for helium? What is the electron configuration of KR? What chemical property determines the placement of the noble gases on the periodi...
How many neutrons are there in an atom of lead whose mass number is 208? What is the difference between atomic mass and mass number? What is the atomic mass number of carbon-13? What is the mass number of phosphorus? What is the chemical symbol for iron?
Chemical Properties: Thechemical propertiesof most isotopes are the same or very similar. This is because chemical reactions generally involve electrons rather than protons or neutrons. Physical Properties: Thephysical propertiesof isotopes differ because the atomic masses (mass numbers, symbol 'A') of...
Add one proton, one neutron, and one electron and you get an atom of beryllium (symbol Be).See how it works? In all atoms, the number of protons and the number of electrons is always the same. So nitrogen has 7 protons and 7 electrons, calcium has 20 protons and 20 electrons, and...

Chapter 1: What is Titanium Metal?Titanium, denoted by the symbol “Ti” and holding the atomic number 22, is a chemical element with an atomic weight of 47.9. It ranks as the ninth most abundant element in the Earth's crust. Titanium is primarily extracted from minerals such as rutile ...
Strontium is an alkaline earth metal. On the Periodic Table of Elements, strontium is given the symbol 'Sr' and the atomic number 38. Strontium is a solid at room temperature and has a melting point of 1431 degrees Fahrenheit. Answer and Explanation: ...
For example, Ca2+is the symbol for a calcium ion that has a positive 2 charge. Since the atomic number of calcium is 20 and the charge is positive, this means the ion has 20 - 2 or 18 electrons. Chemical Elements To be an element, a substance has to at least have protons, since ...
