What is the noble gas configuration?
A noble gas configuration of an atom consists of the elemental symbol of the last noble gas prior to that atom, followed by the configuration of the remaining electrons. So for sodium, we make the substitution of (Ne) for the 1s22s22p6 part of the configuration.

Has an electron configuration of 1s2 2s2 2p6 3s2 3p6 4s2 3d3?
Correct option a fifthExplanation :The electronic configuration of an atom 1s2 2s1 2p6 3s2 3p6 3d3 4s2. In the configuration the last electron of the atom is filled in d sub-shell as 3d3. Thus this element belongs to d-block of the periodic table with group no.
Which of the following has 16 protons 17 neutrons and 18 electrons?
A quick look in the periodic table will reveal that you're dealing with an atom of sulfur, S .
Which atom is composed of 16 protons 16 electrons and 16 neutrons?
sulfur (S) (b) By referring to a periodic table or a table of elements, we see that sulfur (S) has an atomic number of 16. Thus, each atom or ion of sulfur must contain 16 protons. We are told that the ion also has 16 neutrons, meaning the mass number of the ion is 16 + 16 = 32.
How many protons does 134 Ba2+ have?
How many electrons and protons are in a Ba2+ ion? Ba2+ ion has 56 protons and 54 electrons.
How many valence electrons are in Se2 −?
Since the last shell of a selenium ion has eight electrons, the valence electrons of selenium ion(Se2-) are eight.
Which is bigger Se or Se2 chemistry?
Cr3+ is larger than Cr and Se is larger than Se2-.

Which element has an electron configuration of 1s2 2s2 2p6 3s2 3p6 4s2 3d6?
Thus, following the rules on how to fill the orbitals, the electronic configuration of iron (for example) is 1s2 2s2 2p6 3s2 3p6 4s2 3d6 , and it is abbreviated form (Ar) 4s2 3d6.
What isotope has 16 protons 18 electrons 16 neutrons?
Thus, each atom or ion of sulfur must contain 16 protons. We are told that the ion also has 16 neutrons, meaning the mass number of the ion is 16 + 16 = 32. Because the ion has 16 protons and 18 electrons, its net charge is 2–. Thus, the symbol for the ion is 32S2–.
What has 16 protons and 18 neutrons?
So, if there are 16 protons, the element must be sulfur. The mass number for this isotope is 34 – there are 16 protons and 18 neutrons.
