How do you ionize an element? Ionization or ionisation is the process by which an atom or a moleculeacquires a negative or positive charge by gaining or losing electrons, often in conjunction with other chemical changes. The resulting electrically charged atom or molecule is called an ion. ...
A moment's thought shows you can't weigh an atom on a traditional scale. Instead, physicists for over a century have used an instrument called a mass spectrometer. Invented in 1912 by physicist J.J. Thomson and improved incrementally, it works like this: First, physicists "ionize" a gas ...
However, ionizing radiation is so high in energy it can break chemical bonds -- meaning it can charge (or ionize) an atom that interacts with it. At a lower energy, it may strip off a couple of electrons. At a higher energy, it can destroy the nucleus of an atom. This means that ...
The loss or gain of electrons takes place in order to make an atom more stable. As soon as this process occurs, it is no longer called an atom but anion. You can think about electrons being ordered into rings around the nucleus of an atom. The first ring must contain two electrons to...
As its name indicates, it's powerful enough to ionizeatoms—that is, to knock some of an atom's electrons away. In fact, extremely high-energy ionizing radiation can even destroy an atom's nucleus. For most of us, ionizing radiation isn't something we need to worry about on a daily ...
To "ionize" means to "knock an electron off of." When you knock an electron off of an atom, you end up with a free electron (with a negative charge) and an atom missing one electron (with a positive charge). The negative electron is attracted to the plate with a positive voltage, ...
If you introduce many free electrons into the gas by establishing an electrical voltage across it, the situation changes very quickly. The free electrons collide with the atoms, knocking loose other electrons. With a missing electron, an atom loses its balance. It has a net positive charge, ma...
Using Bohr's model of the atom, calculate the energy required to move an electron from a ground state of n = 2 to an excited state of n = 3. Express your answer in both J/photon and kJ/mol. 11. Derive the Bohr model of...
How do you determine the energy of an electron with n = 8 in a hydrogen atom using the Bohr model? According to Bohr's theory, which of the following transitions in the hydrogen atom will give rise to the least energetic photon? a. ...
He began to look into cathode rays, which began an entirely new field of study when they discovered they could ionize the gas inside the tube. This led him down a path where he eventually suggested the model of an atom that included a sphere orbited by electrons. His work earned him a...
