The element with three unpaired electrons in the p sub level is phosphorus. It has a electron configuration of 1s2 2s2 2p6 3s2 3p3, with three unpaired electrons in the 3p sublevel.
Argon does not contain valence electrons.
The valence electrons in group 2 elements are found in the s sublevel. These elements are known as alkaline earth metals and have 2 valence electrons, which occupy the s sublevel of their outermost electron shell.
The sub-level that contains a maximum of three pairs of electrons is the p sub-level. Each p sub-level can hold a maximum of six electrons, meaning it can accommodate up to three pairs of electrons.
Zinc is [Ar] 3d104s2 so there are 2 valence electrons.
The element with 2 electrons in the 1s sub-level, 2 electrons in the 2s sub-level, and 2 electrons in the 2p sub-level is carbon (Atomic number: 6).
The number beside the letter represents the energy level. The letter represents the sub level. The exponent represents the number of electrons in the sub level. So in the case of: 1s^2 1 is the energy level; S is the sub level; ^2 is the number of electrons in the sub level.
The element with three unpaired electrons in the p sub level is phosphorus. It has a electron configuration of 1s2 2s2 2p6 3s2 3p3, with three unpaired electrons in the 3p sublevel.
Argon does not contain valence electrons.
The valence electrons in group 2 elements are found in the s sublevel. These elements are known as alkaline earth metals and have 2 valence electrons, which occupy the s sublevel of their outermost electron shell.
The 5p sublevel is completed with 6 electrons with the addition of the element radon (Rn).
The sub-level that contains a maximum of three pairs of electrons is the p sub-level. Each p sub-level can hold a maximum of six electrons, meaning it can accommodate up to three pairs of electrons.
Zinc is [Ar] 3d104s2 so there are 2 valence electrons.
In an atom of argon (atomic number 18), the valence electrons are found in the 3s and 3p sublevels. Specifically, argon has a complete outer shell with the electron configuration of 1s² 2s² 2p⁶ 3s² 3p⁶. Therefore, the valence electrons are the two electrons in the 3s sublevel and the six electrons in the 3p sublevel, totaling eight valence electrons.
These would be p block elements in group 5 (XV)N, P, As, Sb, Bi
By the group number of the A columns.....go apex :D
yes, both helium and magnesium have 2 valence electrons. the difference is that in helium, the 2 electrons make up an entire electron level. In Magnesium, they only make up the s orbital, or 1st electron sub-level.
