Electrons hold different positions around the nucleus, and they can be in different places at different times. Their positions might be said to be random in that light. It is the energy level of an electron that is fixed. Each electron has a specified Fermi energy level in which it hangs out. This is not a physical location, but is a quantum mechanical characteristic. That's why we say that the electrons occupy an electron cloud. They are not in any specific location, but occupy an area of probability in the electron cloud. The electrons are in motion, and go here and there, but always have the same net energy.
Yes, nonmetals can gain electrons to fill their valence shells. By doing so, they can achieve a stable electron configuration, usually by reaching a full outer shell of electrons (usually 8 electrons, except for hydrogen and helium which only need 2 electrons).
In order to fill their outer most shells and become more stable atoms form BONDS.
Electrons are arranged in energy levels or shells around the nucleus of an atom. The first shell can hold up to 2 electrons, while the second and third shells can hold up to 8 electrons each. The electrons fill up the shells in order of increasing energy levels.
Oxygen has two electron shells because it has eight electrons in total, with two in the first shell and six in the second shell. Atoms tend to fill their outermost electron shell to achieve stability, and oxygen does this by sharing electrons with other atoms or gaining electrons to fill its outer shell.
A neutral atom of calcium has 20 electrons. Electrons fill the electron shells in order of increasing energy levels, with the first shell holding a maximum of 2 electrons, the second shell holding a maximum of 8 electrons, the third shell holding a maximum of 18 electrons, and the fourth shell holding the remaining 2 electrons. Thus, three electron shells (the first three shells) would be completely filled by a neutral atom of calcium.
Yes electrons go on shells , that's the way the are organize . The more shells they fill the greater their atomic number .
Yes, nonmetals can gain electrons to fill their valence shells. By doing so, they can achieve a stable electron configuration, usually by reaching a full outer shell of electrons (usually 8 electrons, except for hydrogen and helium which only need 2 electrons).

Hydrogen has one electron and needs one more. Helium has two electrons and has filled shell. Carbon needs four more electrons to fill the valence shell Oxygen needs two more electrons to fill the valence shell
16 electrons would fill up the first four shells in an atom: 2 electrons in the first shell, 8 electrons in the second shell, 4 electrons in the third shell, and 2 electrons in the fourth shell.

one, it's K, or potassium fill your shells (orbitals, really) in order until you get to 19 electrons K 2-8-8-1 one, it's K, or potassium fill your shells (orbitals, really) in order until you get to 19 electrons K 2-8-8-1
An atom of strontium has 38 electrons, which are distributed across different electron shells based on the aufbau principle and the rules of electron configuration. Strontium, with an atomic number of 38, has electrons filling up to the fifth energy level or electron shell. Therefore, there are five electron shells containing electrons in an atom of strontium.
A neutral atom of calcium has 20 electrons. Electrons fill the electron shells in order of increasing energy levels, with the first shell holding a maximum of 2 electrons, the second shell holding a maximum of 8 electrons, the third shell holding a maximum of 18 electrons, and the fourth shell holding the remaining 2 electrons. Thus, three electron shells (the first three shells) would be completely filled by a neutral atom of calcium.
Electrons fill orbitals in order of increasing orbital energy. The exact order of these energy levels is shown at the related link below.
Ionic bonds help fill the outer shells of atoms by transferring electrons from one atom to another. This results in the atoms achieving a stable electron configuration similar to a noble gas.
