Yes.
Yes, the energy of an electron does vary depending on which energy level it occupies.
true !
true
Transition metals vary in the number of electrons in the highest level. Alkaline earth metals have two electrons in the highest energy level.
Yes, the energy of an electron does vary depending on which energy level it occupies. Electrons in higher energy levels have more energy than those in lower energy levels. The energy of an electron is quantized and can only take on specific values corresponding to the energy levels of the atom.
yes, the Pauli exclusion principle requires every Fermion in the same place to have a different energy (or every Fermion with the same energy to be in a clearly different place). Atoms are small enough that by the rules of quantum mechanics the electrons are effectively in the same place.
A valence electron is one that occupies the highest energy level for any electron in a particular neutral atom. (There may be more than one such electron in a single atom.) It is an electron in the outermost shell of the atom.
The principle that states an electron occupies the lowest energy orbital available is known as the Aufbau principle. According to this principle, electrons fill atomic orbitals in order of increasing energy levels, starting from the lowest energy level. This process continues until all the electrons are placed in the available orbitals, ensuring that the most stable electron configuration is achieved.
Which orbital is being occupied ^^^^ WRONG UPDATE 1/12/16: APEX ANSWER IS The energy level of the electron.
The energy state of an atom refers to the specific energy level that an electron occupies around the nucleus. Electrons can exist in different energy states, or orbitals, depending on the amount of energy they possess. The energy state of an atom is fundamental in determining its chemical and physical properties.
One electron occupies the highest energy sublevel of alkali metals. Alkali metals have one electron in their outermost energy level, making them highly reactive.
No. They are particles. However, when an electron is moving through space it HAS energy. Since an electron has mass it can not be considered to be pure energy. ------------------------------------ Yes they are energy. Energy is the ulimatum and only form energy matter comes out and matter is defined as the one which occupies space. Mass is the quantity of matter contained in a body. Hence though electron is massive particle it has come out of energy.
