The Bohr model was only able to explain the very simplest atoms, like hydrogen. Today's modern day theory is based on mathematics and the properties of waves. The wave model forms the basis for theQuantum Theory.This theory gives the probability of locating electrons in a particular location,...
Hydrogen: Hydrogen is the smallest atom and has an atomic number of just one. On Earth, hydrogen is involved in many organic compounds, but it can also exist on its own as a diatomic, flammable gas. Answer and Explanation:1 Hydrogen atoms usually have a charge of +1. This is because ...
Atomic Number Examples No matter how many neutrons or electrons it has, an atom with one proton is alwaysatomic number 1and always hydrogen. An atom the contains 6 protons is by definition an atom of carbon. An atom with 55 protons is always cesium. ...
Hydrogen is such a better source of fuel. The US Department of Energy states this in their 2007 report. We are a research and development company called thehydrogentoystore. we help semi trucks gain 50 percent more miles per gallon. Imagine how much this would help our economy if we could...
Read more about Sub-atomic particles here Neutron Neutrons neither have a positive charge or a negative charge. Also, they are present in the center of an atom that is the nucleus. Moreover, the neutron is slightly later than protons in shape. Besides, simple hydrogen is the only element ...
Outside the nucleus of an atom: The volume of the rest of the atom (surrounding the nucleus) is occupied by the other type of sub-atomic particle, which is called anelectron, or rather (in all cases except forhydrogen) electronsbecause there are many electrons per atom. ...
If you keep taking things apart, you'll eventually, find that all matter (all the "stuff" that surrounds us) is made from different types of atoms. Living things, for example, are mostly made from the atoms carbon, hydrogen, and oxygen. These are just three of over 100 chemical ...
What is hydrogen's usual atomic structure? What is the electron configuration for hydrogen? How many hydrogen atoms are in a molecule of water? What is the molecular mass of hydrogen? What is the density of metallic hydrogen? An atom of rhodium (Rh) has a diameter of about 2.7 \times 10...
