What sublevel are filling across the Transition Elements?
Transition elements typically fill the 3d and 4s sublevels across the periodic table. As you move across the transition elements from left to right, electrons are added to the 3d sublevel until it is full, before filling the 4s sublevel.
The elements that are characterized by the presence of an incomplete d sublevel are called?
The elements that are characterized by the presence of an incomplete d sublevel are called transition metals. They are found in the d-block of the periodic table and show variability in oxidation states due to the availability of electrons in the d sublevel.
Which set of elements has electrons added to the 4f sublevel as the atomic number increases?
The set of elements that has electrons added to the 4f sublevel as the atomic number increases are the lanthanide series elements, from cerium (Z = 58) to lutetium (Z = 71). The 4f sublevel can hold up to 14 electrons per element, hence as we move across this series, electrons are successively added to the 4f sublevel.
Which elements have 2 electrons in the 4s sublevel?
The elements that have 2 electrons in the 4s sublevel are calcium (Ca) and scandium (Sc).
What elements completes the 2s sublevel?
The 2s sublevel can hold a maximum of 2 electrons.
The elements that are characterized by the presence of an incomplete d sublevel are called?
The elements that are characterized by the presence of an incomplete d sublevel are called transition metals. They are found in the d-block of the periodic table and show variability in oxidation states due to the availability of electrons in the d sublevel.

What name is given to the series of ten elements in which the electrons are filling the 3d sublevel?
The series of ten elements filling the 3d sublevel is called the transition metals. These elements are known for their ability to form multiple oxidation states and their characteristic colored compounds.
Which set of elements has electrons added to the 4f sublevel as the atomic number increases?
The set of elements that has electrons added to the 4f sublevel as the atomic number increases are the lanthanide series elements, from cerium (Z = 58) to lutetium (Z = 71). The 4f sublevel can hold up to 14 electrons per element, hence as we move across this series, electrons are successively added to the 4f sublevel.
Which elements have 2 electrons in the 4s sublevel?
The elements that have 2 electrons in the 4s sublevel are calcium (Ca) and scandium (Sc).
What elements completes the 2s sublevel?
The 2s sublevel can hold a maximum of 2 electrons.
Does zinc have a partially filled 'd' sublevel?
Yes, zinc is a transition metal with a partially filled 'd' sublevel. Its electron configuration is [Ar] 3d10 4s2, meaning it has completely filled the 3d sublevel with 10 electrons and has 2 electrons in the 4s sublevel.
Which element has its outermost electrons in an S sublevel?
The element with its outermost electrons in an S sublevel is found in Group 1 and Group 2 of the periodic table. These elements have their outermost electrons in the S sublevel before transitioning to the D sublevel in subsequent groups.
Which sublevel corresponds to the transition metals in the periodic table?
Most scientists describe a "transition metal" as any element in the d-block of the periodic table, which includes groups 3 to 12 on the periodic table. The f-block 'lanthanide and actinide' series are also considered transition metals and are called "inner transition metals".
What sublevel in group 2 elements are valence electrons?
s
The elements that are characterized by having only five electrons in the p sublevel belong to which family of elements?
Elements with only five electrons in the p sublevel belong to Group 15 or the Nitrogen family on the periodic table. This group includes elements like nitrogen, phosphorus, arsenic, antimony, and bismuth.
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
