How many neutrons are in carbon-14? How many neutrons does curium have? How many protons does einsteinium have? How many protons does californium have? How many protons, neutrons, and electrons does silicon have? How many protons, neutrons and electrons are in tungsten?
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 when ionizing radiation passes through the tissues of the body, it actually has enough energy to damage DNA. It's why gamma rays, for example, are ...
7a). It was found that although the reaction between I0 and Pb0 could happen thermodynamically, a kinetic energy barrier existed in the reaction which made the reaction incomplete. The introduced redox shuttle can effectively transfer electrons in a cyclical manner with the reduction of I0 by ...
Answer: Na,K,Cs (sodium, potassium, and cesium)all are a group one element hence they all are monovalent butaluminumis group -13 elements, therefore, having three electrons in its valence shell hence it forms Al+3 ion and it is trivalent. What is trivalent state? 1 : having a chemical...
There is a strong interest in extending this adoption to magnetic (H) and electric (E) field sensors. A Rydberg atom is an atom excited into a high energy state whose outermost electrons are in very high orbits around the nucleus. Rydberg atoms have many interesting properties including a ...
element. However, because the electrons are added in a scattered way thanks to the rules of electron-orbital filling while the growing positive charge of the nucleus remains concentrated in one small space, the electrons are pulled closer to the nucleus until the noble gases in period 18 of ...
where ne and m* are the number density and band mass of electrons in the conduction band, εeff is the effective dielectric constant which is frequency and carrier density-dependent, εo is vacuum permittivity. The same equation applies to the hole (nh) in the valence band. The red-shift...
Can someone explain why electrons cannot exist in orbitals and why we need to describe their location in terms of probabilities. Explain why one cannot find the north pole of the earth using only a simple compass. If the ice at the poles melts ...
it also needed to have a reliably measurable quantum spin – meaning the orientation of the axis about which the electron rotates, as well as a simple energy level structure – meaning the active electrons are few and their state is simple to identify. Finally, it needed to be easy to vapo...
Thenoble metalsgold, silver, platinum, palladium, and some other elements do not produce a characteristic flame test color. There are several possible explanations for this, one being that the thermal energy isn't sufficient to excite the electrons of these elements enough to release energy in th...
