stronger electrostatic forces of attraction to thenucleus.In addition, Al3+ ion has one less principal quantum shell as compared tothe neutral atom, hence the ionic radius is smaller than its atomic radius.(ii) Explain why aluminium forms compounds with an oxidation state of +3but not sodium....
Answer to: Explain whether the following statement is True or False. Electrons are destroyed when they strike an atom, causing the excited state...
In addition, Al^(3+) ion has one less principal quantum shell as compared to the neutral atom, hence the ionic radius is smaller than its atomic radius.(iii)As compared to sodium, aluminium would require smaller amount of energy to remove the (2^(nd)and 3^(nd)) electrons which are ...
If an orbital holds only 2 electrons, how can you have 8 electrons in an orbit?. What are the key points that are important in describing the periodic trends for atomic radius, first ionization energy, and electronegativity? If a silicon atom has four valence electrons, what is the...
where Z is the atomic number (1 for hydrogen), e is the charge of the electron, m is the mass of the electron, and n is the principal quantum number. - The potential energy (PE) of the electron is given by: PE=−Ze24πϵ0r where r is the radius of the orbit, which is ...
This chapter provides an overview of the equation of state of an imperfect gas. For actual gases, the potential energy is practically equal to zero as soon as the radius is larger than a few ångström. As long as the gas is not too compressed, the average volume available per atom ...
5. Bohr radius was the radius of the circle in which the electron moved in the ground state of the hydrogen atom, according to the bohr theory .根据玻尔理论,玻尔半径是在基态氢原子中电子运动的圆周半径。 6. Being at an energy level higher than the ground state受激发的处于高于基态的能量级的...

The atom is a two-level system, which we consider as a qubit, and is in resonant interaction with an oscillating electromagnetic field, like a laser beam. At time t = 0, the qubit is in state 0 and light is shone on the sample. At time t, in the approximation of resonant ...
