How many non-metals are there in the fourth period?
There are four non-metals in the fourth period: oxygen, sulfur, chlorine, and argon.
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.
How many non metals are there in the third row in the periodic table?
In the third period there are 5 nonmetals, silicon and everything to its right.
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.

Which metals are not metals?
4 metals are not magnetic 1. Aluminium 2. Gold 3. Copper 4. Brass these metals can only be magnetised by very scientific work which i cannot understand 5. don't forget silver...
Is zirconium a transition metal?
Yes Zr (atomic number 40) is the first transitional element in period 5 ('4d-block' metals).
What group is strontium in?
group 2 period 5
In the periodic table what group contains both metals and non metals?
its the boron group which contains one metalloid and 5 metals
How do the periods on the periodic table get their numbers?
if an element has 1 shell in its atom it is in period 1and so on... 2 shells=period 2 3 shells=period 3 4 shells=period 4 5 shells=period 5 6 shells=period 6 7 shells=period 7
What 7 metals react with acid to form salt and hydrogen?
The seven metals that react with acids to form salt and hydrogen are lithium, sodium, potassium, rubidium, cesium, calcium, and strontium. These metals are known as the "active metals" because they readily donate their outer electron to form positive ions and hydrogen gas when in contact with acids.
