Feb 10, 2015. Atomic emission spectra are created when atoms of an element have energy added to them (by heating, or running electric current through an emission tube filled with a gas). With the naked eye, you see a single color of light (which is the sum total of all the colors of light produced by a given element).
The millions of different chemical compounds that make up everything on Earth are composed of 118 elements that bond together in different ways. This module explores two common types of chemical bonds: covalent and ionic. The module presents chemical bonding on a sliding scale from pure covalent to pure ionic, depending on differences in the electronegativity of the bonding atoms. Highlights ...

Answer: 63.62 amu 7. Boron exists in two isotopes, boron-10 and boron-11. Based on the atomic mass, which isotope should be more abundant? Answer: The atomic mass of boron is 10.811; therefore, boron-11 is more abundant because the mass number is closer to the atomic mass. 8. Lithium-6 is 4% abundant and lithium-7 is 96% abundant.
This reflects the simplicity of atomic structure associated with high temperature. The later spectral types K and M have a large number of lines indicating the larger number of atomic structures possible at lower temperatures. Most of the early work on stellar spectra was done early in the 20 th century at Harvard University. The principal ...
