Yes, as shown by this example:
S={*}
G=(S,*)
*:S X S-->S
*(*,*)=*
However, I could not find any nontrivial examples.
In abstract algebra, a generating set of a group is a subset of that group. In that subset, every element of the group can be expressed as the combination (under the group operation) of finitely many elements of the subset and their inverses.
The order of an element in a multiplicative group is the power to which it must be raised to get the identity element.
In mathematics, a subgroup H of a group G is a subset of G which is also a group with respect to the same group operation * defined on G. H contains the identity element of G, is closed with respect to *, and all elements of H have their inverses in H as well.
Given a set and a binary operation defined on the set, the inverse of any element is that element which, when combined with the first, gives the identity element for the binary operation. If the set is integers and the binary operation is addition, then the identity is 0, and the inverse of an integer k is -k. If the set is rational numbers and the binary operation is multiplication, then the identity element is 1 and the inverse of any member of the set, x (other than 0) is 1/x.
Yes, that is part of the definition of a group.
Transition Metals group 3 to group 12 elements
Group 12 of the periodic table contain mercury (Hg).
I believe it is because 0 does not have an inverse element.
halogens & noble gases
It is Nitrogen, located in the amino-group ( -NH2)
Transition Metals group 3 to group 12 elements
The s-block contains group 1-2.
The set of positive integers does not contain the additive inverses of all but the identity. It is, therefore, not a group.
Carbon is an element, and doesn't contain anything but carbon. An acid-group is comprised from carbon, hydrogen and oxygen.
A number does not contain an operation.A number does not contain an operation.A number does not contain an operation.A number does not contain an operation.
Acrylic materials contain Acrylyol group of Acrylic Acid (CH2=CH-COOH)
In abstract algebra, a generating set of a group is a subset of that group. In that subset, every element of the group can be expressed as the combination (under the group operation) of finitely many elements of the subset and their inverses.
