The 3rd energy level of an atom can hold how many electrons?
If the first and second energy levels of an atom are full.what would be the total number of electrons in the atom?
an atom has different energy orbitals: s, p, d, and f. each orbital can hold two electrons. the outside energy or highest energy levels of electrons is called the valence shell or valence electrons. for an atom to be stable it wants the electron configuration for the valence shell to be "s2, p6." to answer your question the outer level of an atom can hold 8 electrons. it is called the valence shell.
An orbit can also be called an energy level, which can be found in an atom. When an atom is 'excited', its electrons move up energy levels, changing it's shape from an S-cloud (circular) to a P-cloud (hourglass). Then, the electrons settle and go bake to their natural state. An 'S' level can hold 2 electrons A 'P' level can hold 6 electrons A 'D' level can hold 10 electrons and an 'F' electron can…
A stairway is a good model for the energy levels in an atom because there is a 'main floor' ( the nucleus ) and steps ( the energy levels ). The nucleus is the start of the stairway of the energy levels, and the other energy levels go off of the nucleus. The first energy level can hold 2 electrons, the second energy level can hold 8. The third energy level can hold 18, and…
An energy level is the fixed amount of energy that a system described by quantum mechanics, such as a molecule, atom, electron, or nucleus, can have. There are no full energy levels in an atom of hydrogen. The first energy level of any atom can hold 2 electrons. Hydrogen only has one electron and it is in the first energy level.
According to quantum mechanics what is the maximum number of electrons that can occupy the third energy level in a ground state atom?
The first energy level in the quantum (current) theory of the atom is the 1s electron orbital, which can hold two electrons. The following energy levels go like this: 1s22s22p63s23p64s24p63d105s25p64d106s2... And so on. (The first number being the energy level, the letter being the shape of the electron orbital, and the superscript being the number of electrons the orbital can hold.)
How do the number of valence electrons affect how likely a substance is to react with another substance?
The number of valence electrons is the number of electrons in the outer energy ring of an atom. The most electrons the first energy level of any atom can hold is two. The rest is 8. If the outer energy level is full, the atom will be less reactive because it cannot add any more electrons to it's current outermost energy level. If it only needs one or two more electrons to fill it's last…
The electron configuration of an oxygen atom is (2, 6). Meaning it has 2 electrons in its first shell and 6 in its second. The energy levels of atoms are limited to how many electrons they can hold. The first energy level can only hold a maximum of 2 electrons the second has a maximum of 8 and the third has a maximum of 18 etc. Hope this Helps!
1st energy level- 2 electrons 2nd energy level- 8 electrons 3rd energy level- 18 electrons To calculate the number of electrons other energy levels can hold, use the formula 2n^2. For example, to calculate the number of electrons the fourth level can hold, the equation would be 2(4)^2. This means that the fourth energy can hold 32 electrons. Same process for other levels.
