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.
The energy of the valence electrons is greater than the energy of the core electrons.
The energy of the valence electrons is greater than the energy of the core electrons.
An atom's energy levels are occupied by electrons. Electrons occupy the energy levels, or electron shells, in order of increasing energy. The lowest energy level is filled first before electrons move to higher energy levels.
The valence electrons
The energy is higher.
The energy is higher.
The energy of moving electrons is electricity. Electrical What_energy_is_the_energy_of_moving_electronsis the passage of electrons through a materials, usually metals.
Core electrons have lower energy levels than valence electrons. Core electrons are closer to the nucleus and are more tightly bound, while valence electrons are in the outermost energy level and have higher energy due to being farther from the nucleus.
Argon has 2 electrons in the first energy level, 8 electrons in the second energy level, and 8 electrons in the third energy level.
Yes, electrons in higher energy levels are farther from the nucleus compared to electrons in lower energy levels. This is due to the increased energy of electrons in higher energy levels.
Electrons in higher energy levels, further from the nucleus, will have higher energy compared to electrons in lower energy levels. Electrons that are in orbitals with higher principal quantum numbers (n) will have higher energy.
Magnesium has two electrons in its first energy level, eight electrons in its second energy level, and two electrons in its third energy level, for a total of 12 electrons.
