Ne (neon) completes n3.
The element that completes the 7s sublevel is radium, with the electron configuration 7s2.
The 5p sublevel is completed with 6 electrons with the addition of the element radon (Rn).
The 3p sublevel is completed by the noble gas element Argon (Ar) which has 18 electrons in total.
The formula for the nitride ion is N3-.
The chemical formula for a nitride ion is N-3.
N3 is a compound. It is the chemical formula for nitrogen gas, which consists of three nitrogen atoms bonded together.
The element that completes the 7s sublevel is radium, with the electron configuration 7s2.
The corresponding element is phosphorus.
The 2p sublevel is completed with six electrons and is found in elements from carbon (C) onwards. The seventh element, nitrogen (N), is the element that completes the 2p sublevel.
The element N3- is the nitride ion, which is formed when nitrogen gains three electrons to achieve a full outer shell. It has a -3 charge and is commonly found in ionic compounds such as alkali metal nitrides.
Not sure about "completes" because the sequence continues. The next number is 20 and you can verify that by fitting the following cubic equation: u(n) = 5*(-n3 + 36n2 - 257n + 558)/12 for n = 1, 2, 3, 4, ...
The 5p sublevel is completed with 6 electrons with the addition of the element radon (Rn).
Azide, N3- ( a linear ion isoelectronic with CO2), or conceivably nitride N3- a monoatomic ion
Let any number be n:- n3/n3 = n*n*n/n*n*n = 1 And in index form: n3/n3 = n3-3 = n0 = 1
A vessel element completes its development in the primary xylem area of growth. It arises from the vascular cambium and matures in the secondary xylem as part of the water-conducting system of the plant.
The last element for which there are claims of discovery is Uus, element 117. That completes the 118 elements on the periodic table.
Formula: N3-
