What element has electron configuration 1s2 2s2 2p6 3s2 3p6 4s2 3d6?
So here the total number of electron is 26 . Now, we have to use the periodic table to find out the name of this element. Look ,Fe is the symbol for iron whose atomic number is 26 .. So 1s2 2s2 2p6 3s2 3p6 3d6 4s2 is the electron configuration of Iron.
Which has electronic configuration AR 3d6?
Thus, Co 3+ is the ion with the desired configuration.
What electron configuration is 1s22s22p63s23p3?
phosphorus
The 1s orbital Given that the electron configuration for phosphorus is 1s22s22p63s23p3, answer the following questions: a.
Which element would have the electron configuration of AR 3d3 for its 2+ ion?
Therefore, the element that forms 2+ ion with electron configuration [Ar] 3d3 is Vanadium (V) with atomic number: 23.

What is the 21st element?
Scandium
Scandium, atomic number 21.
What element has the electron configuration 1s22s22p63s23p4?
The name of the element with electron configuration 1s22s22p63s23p2 is silicon. The second most abundant element in the Earth’s crust, silicon is a metalloid, an element that is neither metal nor nonmetal.
What is the electron configuration of the neon atom?
Neon is the tenth element with a total of 10 electrons. In writing the electron configuration for neon the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for Ne go in the 2s orbital. The remaining six electrons will go in the 2p orbital.
What is the electron configuration of P?
The p orbital can hold up to six electrons. We’ll put six in the 2p orbital and then put the next two electrons in the 3s. Since the 3s if now full we’ll move to the 3p where we’ll place the remaining three electrons. Therefore the Phosphorus electron configuration will be 1s22s22p63s23p3.
