5 groups of elements
Because an atom can hold 8 valence electrons, there are effectively about eight groups on the Periodic Table. However, there are other groups, including the transition metals and the Lanthanide series and Actinide series that go in between groups 2 and 3, forming a kid of "2A" and "2B" group, etc.
5 groups of elements
There are 18 groups in the periodic table of elements.
This depends on whether you do mean sets or if you mean groups as the two are different and often people use the word set when they mean group. 24 groups can be formed and you can calculate this by using the permutation function. 4 possible elements to select from to go into 3 slots, 4P3=24 groups. (Note I said 4 elements not 5, as by definition an element can not be repeated in a set so the set is not {1,2,3,4,4} but {1,2,3,4} unless you mean {1,2,3,44} but this doesn't change anything.)However, while 24 groups can be formed this is not true for sets, groups are structured unlike sets so a group of (1,2,3)≠(2,3,1), but a set{1,2,3}={2,3,1} i.e. the order of the elements matters in a group but not in a set, so only 6 sets of 3 elements can be made compared to 24 groups.
Infinitely many.
Compounds are formed from elements.
There are a total of 18 groups on The Periodic Table of Elements.
13
As many other chemical elements uranium was formed by stellar nucleosynthesis.
Elements located in groups 4 - 12 in the modern periodic table are considered as transition elements. Transition elements should not be confused with the d-block elements which are from groups 3 - 12.
because they have similar properties to the other elements in their groups
s block elements: groups 1-2 d block elements: groups 3-12 p block elements: groups 13-18
It is said that when sun dies from hydrogen to iron elements are formed and when busted spread in space .the other elements are formed by chemical reaction by these elements
A compound is formed when elements join together.
