What is 2s22p5?
Fluorine. (He)2s2 2p5. 2P3/2. 17.4228. 10.
What is the name of the element with a valence electron configuration of 3s23p2?
silicon
Because there are two electrons in the p-orbital, the column (or group) that this element is in will be the second in the 3p row. The element in the second column of the p-orbitals and third row would be silicon (Si).
Which is the electronic configuration of 1s2, 2s2?
The sum of the electrons in 1s2 2s2 2p4 = 8 and this is the electron configuration of oxygen. Oxygen has 6 valence electrons and it can gain two more to form a stable Noble Gas structure, hence it can form a 2+ ion. Generally, atoms whose configurations have 3 or more electrons in the p sub level form anions.
What is the electron configuration of element sodium?
This electronic configuration belongs to the element sodium. In first shell 2 electrons are present, that too in s sub shell. 2 electrons each in 2px, 2py,2pz orbitals. Only one electron present in s subshell of 3 rd shell.
Which is atom can form an anion in 1s2 2p6 3S1?
The sum of the electrons in 1s2 2s2 2p6 3s1 = 2 + 2 + 6 + 1 and this is the electron configuration of sodium. Sodium does not form anions (it is an alkali metal so the only ion it can form is when it loses its one valence electron and this is a 1+ cation).
Which is the right orbital configuration for iron?
The right orbital configuration for iron (Fe) is 1s2 2s2 2p6 3s2 3p6 4s2 3d6 because it has been written according to Afbau’s principle. Also called his diagonal rule. In writing the electron configuration, you must fill in electrons into orbitals of low energy levels before moving on to fill orbitals of higher energy levels.
