All the noble elements to the far right of the Periodic Table have their s and P sublevels in their valence shell filled, hence they are nonreactive.

What column contains elements whose electron configuration end with d4?
what column of the periodic table contains elements whose electron configurations end with d4
How would you justify the presence of 18 elements in the fifth of period of periodic table?
In the fifth period of the periodic table, the atoms of the elements in the first two groups are adding 1 and 2 electrons, respectively, to their highest energy 5s sublevel. Starting in group 3/IIIB and going through group 12/IIB, the atoms of those elements are adding electrons to their highest energy 4d sublevel. Since the d sublevel can contain a maxium of 10 electrons, there are 10 elements whose atoms are filling the 4d sublevel. Once the 4d sublevel is filled, the next higher energy sublevel is the 5p sublevel. Starting with the group 13/IIIA elements, the 5p sublevel is being filled. Since a p sublevel can contain a maximum of 6 electrons, there are six elements whose atoms are filling the 5p sublevel. 5s sublevel filling: 2 elements 4d sublevel filling: 10 elements 5p sublevel filling: 6 elements --------------------------------------- Total: 18 elements For a printable periodic table that includes electron configurations, go to the following link: http://www.nist.gov/pml/data/periodic.cfm
Row of elements whose properties change gradually?
Period in the periodic table.
How many orbitals are completely filled in an atom whose electron configuration is 1s2 2s2 2p3?
Two orbitals.
How many orbitals are completely filled in an atom whose electron configuration is 1s2 2s2 2p6 3s1?
5
Why do the nonmetals in group 18 rarely react with other elements to form compounds?
They are the noble gases whose outermost (valency) orbitals are full.
What group occupies the large middle section of the periodic table?
its d-block i.e. elements whose outermost electrons lie in d-subshell.
Why do atoms of each element have 1 outer-level electron?
They don't. Of the main group, or representative elements, group 1 elements are the only ones whose atoms have only 1 electron in their outermost energy levels.
Would an atom whose outermost energy level full want to participate in a chemical reaction?
No.
How many orbitals are completely filled in an atom of an element whose atomic number is 19?
Three completely filled orbitals.
Whose mythology is filled with references to the healing power of music?
chinese
What column contains elements whose electron configuration end with d4?
what column of the periodic table contains elements whose electron configurations end with d4
Why d block element are called transition element?
d block elements, transition metals, transition elements are synonyms.The definition of d block after the IUPAC recommendation is "an element whose atom has a partially filled d sub-shell, or which can give rise to cations with an incomplete dsub-shell".
Is a set whose elements can be counted or has a limited number of elements?
A finite set or a countably infinite set.
Type of matter whose atoms are all the same?
Elements
What is the outermost structure of a plant cell?
The outermost structure of a plant cell is a cell wall. Plant cells have cell walls for extra protection as they cannot move like animals and protists, whose outermost cell structure is the cell membrane, a thinner protective cover.
How many electrons are in the first period?
for all elements, excluding hydrogen, there are 2 electrons in the first energy level. Hydrogen is the exception of this because it only has a single electron, thus it only has 1 in its first and only energy level.
