What is the identity element of the quaternion group?
If you mean in the group {1, -1, i, -i, j, -j, k, -k}, the identity element is 1.
What is the order of an element of a group?
The order of a group is the same as its cardinality - i.e. the number of elements the set contains. The order of a particular element is the order of the (cyclic) group generated by that element - i.e. the order of the group {...a-4, a-3, a-2, a-1, e, a, a2, a3, a4...}. If these powers do not go on forever, it will have a finite order; otherwise the order will be infinite.
Give two reason for the set of odd integers is not a group?
Assuming that the question is in the context of the operation "addition", The set of odd numbers is not closed under addition. That is to say, if x and y are members of the set (x and y are odd) then x+y not odd and so not a member of the set. There is no identity element in the group such that x+i = i+x = x for all x in the group. The identity element under addition of integers is zero which is not a member of the set of odd numbers.

A group of employees bought a get-well gift for a coworker the gift cost 16.06 If there are 22 employees in the group how much does each employee need to contribute?
The correct answer is $0.73
Which is the correct formula for the ionic compound formed between sodium and sulfur?
The correct formula for the ionic compound formed between sodium and sulfur is Na2S. Sodium is a group 1 element with a +1 charge, and sulfur is a group 16 element with a -2 charge. Therefore, two sodium atoms are needed to balance the charge of one sulfur atom.
How is a compound different then an element?
Yea an element can not be broken down anymore but a compound is a group of elements
Element x is in gropu 2 and element y is in group 17 what happens when a compound is formed between these two atoms?
When a compound is formed between an element from group 2 (such as x) and an element from group 17 (such as y), they will likely combine in a 1:2 ratio to form an ionic compound. The Group 2 element will lose 2 electrons to achieve a stable octet, becoming a 2+ cation, while the Group 17 element will gain 1 electron to achieve a stable octet, becoming a 1- anion. This results in the formation of a compound with a 1:2 ratio of cations to anions.
Is Li a element or a compound?
Li is an element. It is in the 1st group. It is an alkaline metal element.
Suppose an element x is in group 2a and an element y is in group 7a the empirical formula for the compound between x and y?
The empirical formula for the compound between x and y would be xy. Since x is in group 2a and y is in group 7a, their charges would be 2+ and 7-, respectively. To balance the charges, one x would combine with three y to form the compound with the formula XY3.
What is the correct formula for a lithium ion and bromine ion compound?
The formula for the compound formed between lithium ion (Li+) and bromine ion (Br-) is LiBr. Lithium being a group 1 element with a +1 charge and bromine being a group 17 element with a -1 charge, they combine in a 1:1 ratio to form a stable ionic compound.
What is the formula for ionic compound formed between Sr and S?
The formula for the ionic compound formed between strontium (Sr) and sulfur (S) is SrS. Strontium is a group 2 element with a 2+ charge, while sulfur is a group 16 element with a 2- charge. Therefore, they combine in a 1:1 ratio to form a neutral compound.
Is kyrpton a compound?
Krypton is an element not a compound. It is a noble gas (group 0) and has atomic number 36. It is a very stable and unreactive element.
Is helium compound mixture or element?
Helium is an element. It is in the 18th group of the periodic table. It is a noble gas.
Is magnesium metal a compound or a element?
An element in group 2 of the Periodic Table; the alkali earth metals.
What is the formula for the ionic compound for Sr and Te?
The formula for the ionic compound formed between strontium (Sr) and tellurium (Te) is SrTe. Strontium is a group 2 element, providing a 2+ cation, while tellurium is a group 16 element, providing a 2- anion. The compound is neutral and balanced with a 1:1 ratio of Sr to Te.
How can one determine the valence of an element in a chemical compound?
The valence of an element in a chemical compound can be determined by looking at the group number of the element on the periodic table. The group number indicates the number of valence electrons an element has. For example, elements in group 1 have a valence of 1, elements in group 2 have a valence of 2, and so on. The valence of an element is important in understanding how it will react with other elements to form compounds.
