The amount of electrons. Electrons fill according to occupying the lowest energy state, and also by not spin pairing until each suborbital of same energy has one electron in each. Beware when entering the d orbitals, i.e. Cr and Cu, they will prefer to fill 4s1,3d5 and 4s1,3d10 respectively as this is more satisfying in being the lowest energy state.
What else can I help you with?
Which atom is more chemically reactive an atom with a partly filled energy level or an atom with all energy levels completely filled and why?
If all the electron orbitals are filled then the atom is inert. It will not chemically react with anything. If an atom has empty spaces in the outer orbit, it will react with other elements. Electrons from other elements can share positions in the outer orbits.
In a normal radium atom how many energy levels contain at least one atom?
In a normal radium atom, which has an atomic number of 88, there are seven energy levels (or electron shells) that can contain electrons. These energy levels are filled with electrons according to the Aufbau principle, with the outermost levels containing fewer electrons. Thus, all seven energy levels in a neutral radium atom contain at least one electron.
What does t he energy levels of an atom hold?
The energy levels of an atom hold electrons.
What is the neutral atom that has the first two energy levels filled and has 4 electrons in its third energy level?
You appear to mean silicon. Please see the link.
What three conditions of an atom control its strength of attraction and size?
The number of protons in the nucleus determines the strength of attraction, with more protons leading to stronger attraction. The number of energy levels or electron shells determines the size of the atom, with more energy levels leading to a larger size. The number of electrons in the outermost shell determines reactivity, with atoms tending to gain, lose, or share electrons to achieve a stable outer shell configuration.
Which atom is more chemically reactive an atom with a partly filled energy level or an atom with all energy levels completely filled?
the one that is completely filled
Where are electrons arranged?
Electrons are arranged in energy levels or shells around the nucleus of an atom. These energy levels can accommodate a specific number of electrons, and electrons are distributed in these levels based on their energy. The electron configuration of an atom determines its chemical properties.
What determines which photon an atom can absorb or emit?
An atom can absorb or emit photons based on its energy levels and electronic structure. When a photon energy matches the energy difference between two energy levels in the atom, it can be absorbed or emitted. This is governed by the quantized nature of energy levels in atoms.
Are the highest energy levels always filled first?
No, the tendency is to fill out lower energy levels first.
What atom has its first three energy levels which are fully occupied by electrons?
Neon has the 1s2, 2s2, and 2p6 levels filled.
What is the neutral atom that has its first two energy levels filled has 6 electrons in its third energy level and has no other electrons?
The neutral atom with the specified electron configuration has 10 electrons in total. This atom is neon (symbol: Ne), which has a total of 10 electrons and has its first two energy levels filled with 2 and 8 electrons, respectively, while the third energy level contains 6 electrons.
How are the energy levels filled with electrons for a phosphorus atom?
In a phosphorus atom, the energy levels are filled with electrons according to the aufbau principle, which states that electrons fill the lowest energy levels first before moving to higher energy levels. Phosphorus has 15 electrons, which fill the 1s, 2s, 2p, 3s, and 3p orbitals in that order.
How many energy levels are partially or fully occupied in a neutral atom of calcium?
A neutral atom of calcium has five energy levels that are partially or fully occupied. These energy levels are filled with electrons according to the Aufbau principle, with the first two levels (K and L) being fully filled while the remaining three levels (M, N, and O) are partially filled.
How many elecrtons shells would be filled by a neutral xenon atom?
The first 3 energy levels are filled, the 4s and 4p and 4d sublevels are filled, and the 5s and 5p sublevels are also filled. So only the first three energy levels are completely filled. The fourth and fifth energy levels are partly filled. The electron configuration is 1s22s22p63s23p63d104s24p64d105s25p6 or [Kr]4d105s25p6.
Which energy levels contain electrons that have the lowest energy?
Electrons located in the innermost energy levels (such as the 1s level) have the lowest energy. These energy levels are closest to the nucleus and are filled first in an atom according to the aufbau principle.
What are the energy levels of an atom occupied by?
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.
Which atom is more chemically reactive an atom with a partly filled energy level or an atom with all energy levels completely filled and why?
If all the electron orbitals are filled then the atom is inert. It will not chemically react with anything. If an atom has empty spaces in the outer orbit, it will react with other elements. Electrons from other elements can share positions in the outer orbits.
