If the first energy level is complete with two electrons then what has two elements?
If the first energy level is complete with two electrons, then the elements hydrogen and helium have two elements in their electron configuration. Hydrogen has one electron in its first energy level, while helium has two electrons filling its first energy level.
When elements gain three electrons to fill its valence energy level?
When these elements have five electrons on the outermost shell of electrons.
What is the number of electrons in the 1st energy level of magnesium?
All elements except hydrogen have two electrons in the first energy level.
Electrons in wich energy level determines the chemical behavior of elements?
the outermost energy level! ( :
How many electrons are in the highest occupied energy level in Group 8A?
Group 8A elements have 8 valence electrons. This means that the highest occupied energy level in Group 8A elements will have 8 electrons, as the maximum number of electrons in an energy level is 8 based on the octet rule.
How many electrons do beryllium and magnesium have in there outer energy levels?
Beryllium and magnesium have two electrons in their outermost energy level, as do all Group 2 elements.
Which elements have 3 energy levels with only 4 electrons in the last energy level?
oxygen
How are families within the periodic table similar?
Elements within the same period have the their valence electrons in the same principle energy level. For example, those elements in period 2, have their valence electrons in the 2nd energy level.
How many electrons are in the highest occupied energy level of a 7A element?
7 electrons would be in the highest occupied energy level of a 7A element. Group 7A elements have 7 valence electrons, which occupy the highest energy level of the atom.
What is the number of electrons in the highest occupied energy level of an element in Group 15?
The number of electrons in the highest occupied energy level of an element in Group 15 is 5. Group 15 elements have 5 valence electrons, which occupy the highest energy level.
Which elements fits the following description 2 electrons in the n3 energy level?
The element that fits this description is lithium. It has 3 electrons, with 2 of them in the third energy level.
How is an elements period related to its its electron confuguation?
An element's period is related to its electron configuration by indicating the energy level of its outermost electrons. Each period corresponds to a new energy level, with elements in the same period having electrons in the same principal energy level. Electron configuration describes the arrangement of electrons in these energy levels, with each period accommodating a specific number of electron shells.
