Bromine, Br, [Ar] 3d10 4s2 4p5
The group number 17 comprises of elements that has seven electrons in their own outer level.
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.
This element is likely chlorine (Cl), which has 7 valence electrons and 3 filled energy levels with a partially filled 4th energy level.
Fluorine (F) with 7 outermost electrons
Fluorine is the element that has 7 valence electrons.
The group number 17 comprises of elements that has seven electrons in their own outer level.
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.
The element with an electron arrangement of 2, 8, and 7 is fluorine (F), which has 9 electrons. The first energy level can hold a maximum of 2 electrons, the second level can hold a maximum of 8 electrons, and the third level can hold a maximum of 7 electrons for a total of 17 electrons in its neutral atom.
This element is likely chlorine (Cl), which has 7 valence electrons and 3 filled energy levels with a partially filled 4th energy level.
Fluorine (F) with 7 outermost electrons
Its electrons per engergy level are: 2, 8, 18, 7. This gives it a total of 35 electrons.
Fluorine is the element that has 7 valence electrons.
