How many non-metals are there in the fourth period?
There are four non-metals in the fourth period: oxygen, sulfur, chlorine, and argon.
How many energy levels does period 5 have?
Period 5 of the periodic table has five energy levels. These energy levels correspond to the principal quantum number ( n = 1, 2, 3, 4, ) and ( 5 ). The elements in this period include the transition metals, and they fill the 4d subshell as well as the 5s and 5p subshells.
What are the group number and period of the elements in the periodic table if it has an atomic number of 40?
Zirconium(Zr) has an atomic number of 40. It is in Group 4 and Period 5.
Period 5 in the periodic table?
Period 5 in the periodic table includes elements from 37 (Rb) to 55 (Cs). This period consists of transition metals, lanthanides, and actinides, as well as nonmetals and metalloids like iodine and tellurium. Elements in period 5 generally have increasing atomic numbers and atomic masses from left to right.

What is the name of the halogen that is in period 2?
The halogens with their period no. are :- Fluorine (2) Chlorine (3) Bromine (4) Iodine (5) Astatine (6) Tennessine (7) The last two are radio-active and not fully characterised. You will not find them in a school/college lab. NB There are NO halogens in period '1'. The only elements in period '1' are hydrogen(H) and helium(He).

What is the identity of the metal cation Ca2 Sr2 Ba2?
The metal cations Ca²⁺ (calcium), Sr²⁺ (strontium), and Ba²⁺ (barium) belong to the alkaline earth metals group in the periodic table. They are all divalent cations, meaning they each have a +2 charge. Calcium is found in period 4, strontium in period 5, and barium in period 6. These metals are known for their reactivity, particularly with water and halogens, and are commonly found in various compounds.
Is Niobium an alkali metal?
No, Nb, atom no. 41, is in group 5 (period 5) of the transition metals (4d-trans.).Alkali metals are in group 1, like Na and K.
