Which has the highest occupied energy level? electron The highest occupied energy level in an atom is the electron-containing main energy level with the highest number. What is the highest energy level sodium’s electrons occupy?
Which has the highest occupied energy level?
The highest occupied energy level in an atom is the electron-containing main energy level with the highest number.
What is the highest energy level sodium’s electrons occupy?
third energy level
In a sodium atom, the highest-energy principal energy level containing electrons is the third energy level, and that energy level contains one electron. The transition elements (or transition metals, for they are all metals) are those elements found in the short columns of the d block.
Which configuration is the configuration of the highest occupied energy level for beryllium?
Valence electrons are the electrons in the highest occupied principal energy level of an atom….What makes a particular element very reactive and another element non-reactive?
What is the highest energy level occupied by the electrons?
The valence electrons are the electrons in the highest energy level and the ones involved in ion and bond formation. Knowing the number of valence electrons will allow us to predict how a particular element will interact with other elements. Electrons in lower energy levels are called the core electrons.
What is the highest occupied energy level for phosphorus?
Phosphorus has electron configuration, 1s22s22p63s23p3. The highest-numbered shell is the third shell (3s23p3): 2 electrons in the 3s subshell and 3 electrons in the 3p subshell. That gives a total of 5 valence electrons.
What is the highest occupied shell?
In the third period of the table, the atoms all have a neon-like core of 10 electrons, and shell #3 is occupied progressively with eight electrons, starting with the 3s-orbital. The highest occupied electron shell is called the valence shell, and the electrons occupying this shell are called valence electrons.
Why does sodium have 3 energy levels?
Period 3. Explain that sodium has 11 protons and 11 electrons. There are 2 electrons on the first energy level, 8 electrons on the second level, and 1 electron on the third energy level. Explain that the second energy level can only have 8 electrons so the next electron in sodium has to be on the next (third) level.
What is the correct electron configuration for beryllium?
What is the complete electron configuration of mg2 +?
The nex six electrons will go in the 2p orbital. The p orbital can hold up to six electrons. We’ll put six in the 2p orbital and then put the remaining two electrons in the 3s. Therefore the Magnesium electron configuration will be 1s22s22p63s2.
What is the highest occupied energy level of phosphorus?
How do you determine the highest energy level?
Electrons in an atom are contained in specific energy levels (1, 2, 3, and so on) that are different distances from the nucleus. The larger the number of the energy level, the farther it is from the nucleus. Electrons that are in the highest energy level are called valence electrons.
