The number of protons in an atom is called the atomic number and it tells you what type of atom you have. An atomic number of 1 means the atom is hydrogen, atomic number 2 means helium, 3 means lithium, 4 is beryllium, and so on. The total number of protons and neutrons added ...
Explain how the metric units for length, volume and mass are related. Measurement: Measurement refers to the act of determining the physical characteristics of a given object- such as length, volume, and mass- for a given purpose. Making precise measurements is very important for many...
The atomic mass of the element is determined by the combined masses of neutrons and protons. True or false? Explain. Answer and Explanation: The atomic mass or atomic weight of an element (or put it in simple term, mass of an atom) is found...
Define the term "alloy" and provide an example. Is a substance that is attracted to an external magnetic field diamagnetic or paramagnetic? Explain. Is lead metal classified as a pure substance (element or compound) or a mixture? Explain. ...
2 Explain why,going down a group,the atomic radius increases even though the number of protonsin the nucleus that can attract the electrons increases.\x05\x05\x05\x05\x05\x05\x05\x05\x05\x05\x05\x05\x05\x05\x05\x05\x05\x05...
is in a quantum superposition of states; rather, it is our less than infinite accuracy of measurement and knowledge of those orbits, plus their evolution under the influence of less-predictable effects like space weather or other still unidentified additional factors, that makes long-term estimates...
The intermolecular forces of attraction (IMFA) are the interactions occurring between molecules. These are much weaker than the chemical bonds but are essential in determining the overall property of the compound. For instance, the fact that water has a higher boiling point t...
Photo: The basic concept of the arc lamp. An electric discharge passes between two carbon electrodes, giving off light. Strictly speaking, we use the term arc lamp to mean one, particular type of arc lamp with carbon electrodes and air in between them. Before Edison, Swan, and their contem...
