Which energy sublevel is being filled by the elements Ce to Lu?
The energy sublevel being filled by the elements Ce to Lu is the 4f sublevel. These elements are part of the lanthanide series and have their outermost electrons entering the 4f orbital.
Which energy sublevel is being filled by the elements Rb to Sr?
The energy sublevel being filled by the elements Rb (rubidium) to Sr (strontium) is the 5s sublevel. These elements are in the fifth period of the periodic table, and in period 5, the s sublevel starts to fill up with electrons.
elements in which the s and p arbitals in the outer shell are entirely filled are?
These elements, known as the alkali metals (group 1A) and alkaline earth metals (group 2A), are those in which the outer-shell s orbitals are being filled. On the right is a block of six columns. These are the elements in which the outermost p orbitals are being filled.
What are 3 properties and 3 examples of metallic elements?
Properties of metals include being conductors of electricity and heat, malleable, and ductile. Examples of metallic elements include gold, copper, and silver.
How did Moseley solve the problem of the elements that did not fit the pattern according to their properties?
He rearranged the table, placing elements in order of atomic weight, not by property. This resulted in elements that had similar properties but were actually very unrelated from being placed incorrectly, and lead to them being put where it made more sense. After the reordering, they were also very much aligned by their properties, thus fixing the problem of those elements that didn't fit.
Why was leaving spaces and gaps in the periodic table later vindicated?
Leaving spaces and gaps in the periodic table allowed for prediction of new elements and their properties, which were later discovered and filled in. This vindicated the decision to leave gaps, as it demonstrated the power of the periodic table in organizing and predicting the properties of elements.

Which energy sublevel is being filled by the elements Y-Cd?
The elements Yttrium (Y) and Cadmium (Cd) fill the 4d energy sublevel.

Are elements arranged according to blocks corresponding to the orbitals being filled?
Yes, elements are arranged in the periodic table according to blocks that correspond to the orbitals being filled. For example, the s-block elements fill the s-orbital, the p-block elements fill the p-orbital, the d-block elements fill the d-orbital, and the f-block elements fill the f-orbital. This organization provides a structured way to represent the electron configurations of elements.

Where are the electrons being added from in the 4f orbitals?
Electrons are added to the 4f orbitals from the 5d orbitals in the lanthanide and actinide series of elements. The 4f orbitals are filled after the 5d orbitals are filled due to the overlap in energy levels, leading to the stability of the 4f electrons in these elements.
What does Dimitri Mendeleev get credit for creating?
He is credited as being the creator of the first version of the periodic table of elements. Using the table, he predicted the properties of elements yet to be discovered.
