What can be said about the electron configurations of all the elements in a group?

Elements in a group have the same number of valence electrons, giving them similar electron configurations. The electron configurations differ by the number of filled inner shells, leading to a trend in chemical reactivity within the group. The periodic table is organized based on these similarities in electron configurations within groups.


Electron configurations is most likely to result in an element that is relatively inactive?

A filled highest occupied principal energy level


What is true about the electron configurations of the noble gases Decent levels are partially filled be the electrons with the highest energy you sublevel see the highest occupied SN?

The valence electron shell of noble gases is full.


What information about a representative element can you get from just knowing its group number?

You can determine the number of valence electrons from the group number of a representative element. For example, elements in group 1 have 1 valence electron, while elements in group 14 have 4 valence electrons. Additionally, elements in the same group tend to have similar chemical properties due to their shared electron configurations.


An element whose highest occupied s sublevel and a nearby f sublevel generally contain electrons?

This description fits elements in the lanthanide and actinide series of the periodic table. These elements have their highest occupied s sublevel and a nearby f sublevel containing electrons due to the electron configurations in their atoms.


What is the name given to the electron in the highest occupied energy level?

The electron in the highest occupied energy level is known as the valence electron. These electrons are involved in the formation of chemical bonds and determine the element's chemical properties.


Neutral atoms with an s's or p's electron configuration in the highest energy level are best classified as what?

Neutral atoms with s or p electron configurations in the highest energy level are classified as main group elements or representative elements. These elements typically exhibit a wide range of chemical properties due to their varying numbers of valence electrons.


How many electrons are in the highest occupied energy level of the sodium?

Sodium: Na(2, 8, 1 ) so there is one electron in the highest (3rd) level


What electron configuration is mostly likely to result in an element that is relatively inactive?

a filled highest occupied principal energy level


Is true about the electron configurations of the noble gases?

the elections with the highest energy are in an f sub level. your welcome :))


How does the bohnr model of the atom relate to the periodic table?

The Bohr model of the atom helped explain the arrangement of electrons in discrete energy levels or shells around the nucleus. This concept of electron shells provided a basis for understanding the organization of the elements on the periodic table, where elements are arranged by increasing atomic number and by recurring chemical properties based on their electron configurations.


What is taking place with the elements in the s p d p and f blocks?

They relate to the sub orbital type, or the highest energy orbitals that are occupied in a given element that falls under the subsequent block of the periodic table. Plato: Its not D. none of the above
