Neils Bohr
Electrons are the atomic particles found in the orbitals or energy levels outside the nucleus of an atom. Electrons have a negative charge and are involved in chemical bonding and determining an element's reactivity.
In Bohr's atomic model, electrons orbit the nucleus in specific energy levels. Ionization energy is the energy required to remove an electron from an atom. Electrons in higher energy levels have greater ionization energy because they are held more tightly by the nucleus.
None. Electrons are found in energy levels outside the nucleus, not in it. An atomic number of 20 tells you there are 20 protons in the nucleus of an atom, and 20 electrons in energy levels (or shells or orbitals depending on which model of the atom you are using) outside the nucleus.
Yes, atomic spectra can be explained and understood through quantum mechanics. Quantum mechanics provides a framework to describe the discrete energy levels of electrons in atoms, leading to the observation of specific wavelengths in atomic spectra. The theory helps explain phenomena such as line spectra and transitions between energy levels within an atom.
Electrons are placed on the rings (or energy levels) of an atom. The number of electrons in each ring is determined by the atom's atomic number and follows specific rules based on the electron configuration.
distance from the atomic nuclei
Electrons do not have a color because they are subatomic particles. Their behavior in atomic structures is determined by their energy levels and interactions with other particles, rather than their color.
Electrons are placed in determined energy levels.
Electrons tend to settle in energy levels around an atom's nucleus. These energy levels are called orbitals, which can hold a specific number of electrons based on their energy. Electrons will fill the lowest energy levels first before moving to higher energy levels.
According to atomic theory, electrons are usually found in energy levels or shells surrounding the nucleus of an atom. They exist in specific orbits around the nucleus and are associated with specific energy levels.

Atomic spectra are discontinuous because they result from the quantized energy levels of electrons within an atom. Electrons can only exist at specific energy levels, leading to distinct spectral lines corresponding to transitions between these levels. This quantization of energy in atoms gives rise to the phenomenon of discrete spectral lines.
None. Electrons are found in energy levels outside the nucleus, not in it. An atomic number of 20 tells you there are 20 protons in the nucleus of an atom, and 20 electrons in energy levels (or shells or orbitals depending on which model of the atom you are using) outside the nucleus.
There are 8 electrons in the second energy level of magnesium. This can be determined because magnesium has an atomic number of 12, meaning it has 12 electrons in total. The first energy level is filled with 2 electrons, leaving 10 electrons to distribute in the remaining energy levels, with 8 of those in the second level.
Nitrogen has atomic number = 7. The outer shell has 5 electrons, it requires 3 more electrons to complete the outer energy shell.
