What is the electron configuration for Fe+?
What is the electron configuration for Fe+?
The correct electron configuration is [Ar]3d64s2 This means for Fe+ , so far, the 4s orbital is such that the first electron in the 4s orbital (with ms=−1/2 ) is lower in energy than the sixth 3d electron.
What element has the electron configuration 1s22s22p63s23p2?
element Silicon
2 Answers. BRIAN M. The electron configuration 1s22s22p63s23p2 is the element Silicon.
Which neutral atom has the following electron configuration 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2?
antimony atom
So, an antimony atom with charge +2 has an electron configuration of 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p1.
Why is Fe2+ larger than Fe3+?
Fe2+ is greater in size as it has lost less electrons than Fe3+ . So, the nuclear pull is more strong on Fe3+ decreasing the atomic size. Thus Fe2+ is greater in size.
What is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6?
So, an antimony atom with charge +2 has an electron configuration of 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p1.

Why is Fe 3+ smaller than Fe2+?
Yes because Fe3+ has one less electron the nuclear charge acting on electrons is larger and electronic repulsion is lesser. This causes the outer shell of Fe3+ to be pulled a little more inwards compared to Fe2+. Hence it’s size is smaller.
Which is larger Mg2+ or Ca2+?
Cations are smaller than their parent atoms, and so the Ca2+ ion is smaller than the Ca atom. Because Ca is below Mg in group 2A of the periodic table, Ca2+ is larger than Mg2+. Consequently, Ca > Ca2+ > Mg2+.
What does 1s2 2s2 2p6 mean?
b. 1s2 2s2 2p6 This represents 2 electrons in the s subshell of the first energy level , 2 electrons in the s subshell of the second energy level and 6 electrons in the p subshell of the second energy level.
What does the 2 mean in 3s2?
The superscript after the letter But what do the superscripts 2 after the “s” and 6 after the “p” refer to? These refer to the number of electrons in that particular orbital/shell. So, for neon, there are 2 electrons in the 1s shell, 2 electrons in the 2s shell, and 6 electrons in the 2p shell.
How to calculate electron configuration?
Method 3 of 4: Using an ADOMAH Periodic Table Understand the ADOMAH Periodic Table. This method of writing electron configurations doesn’t require memorization. Find your atom in the ADOMAH table. To write electron configuration of an element, locate its symbol in ADOMAH Periodic Table and cross out all elements that have higher Count orbital sets up to your atom.
What is the noble gas configuration of uranium?
The electron configuration for Uranium (U) is based upon the placement of uranium in the fourth column of the actinide series or f block. This notation can be written in core notation or noble gas notation by replacing the 1s22s22p63s23p64s23d104p65s24d105p66s24e145d106p6 with the noble gas [Rn].
How many valence electrons does uranium have?
Uranium is a chemical element with the symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons.
