What is the group 3b-12b elements know as?
Transition metals or d-block elements
What is the group number for Lanthanides and Actinides?
Rare Earth elements or lanthanides are placed in the period 6 of the periodic table of Mendeleev. Actinoids are placed in the period 7 of the periodic table of Mendeleev.
What is a group on a periodic table?
A vertical column on the Periodic table on the periodic table is called group. There are 18 groups on the table. These groups are also referred to as families. Each element in a group has the same number of valence electrons and, therefore, similar chemical properties (there are some exceptions though).
How many electrons are in the valence shell for Mg?
Mg or Magnesium has 2 electrons in its Valence shell. If you have the right Periodic Table it should have numbers 1A, 2A,... 3B, ect listed above each column. These numbers represent the number of Electrons in the valence shell of all the elements in that Column.
Where Do You Usually Find The Element scandium?
Scandium is a natural chemical element; minerals containing scandium: thortveitite, euxenite, gadolinite. In the universe scandium is formed during the supernova nucleosynthesis (the so called r-process).
What is the group 3b-12b elements know as?
Transition metals or d-block elements
Is (-3b) to the fourth power equal to -12b to the fourth power?
No, it is not.
How do you solve fractions negative 9 over 4b minus 10 over 3b equals negative 67 over 6?
-9/4b -10/3b =-67/6 9/4b +10/3b = 67/6 27/12b + 40/12b = 67/6 67/12b =67/6 12b = 6 b = 6/12 b=1/2
What is 12b plus 8 in factorizing terms?
4(3b+2)
Combine like terms 15b plus 13c-12b plus 10c plus 8?
15b + 13c - 12b + 10c + 8 = 3b + 23c + 8
Solve 4 times the quantity of 3b minus 5 is less than negative 31 plus 12b?
4(3b - 5) < -31 + 12b12b - 20 < -31 + 12b, this is not true because -20 > - 31, so that the solution for the given inequality does not exist.
How do you solve 12b-5 equals 15b plus 5?
12b - 5 = 15b + 5 subtract 12b from both sides 12b - 12b - 5 = 15b - 12b + 5 - 5 = 3b + 5 subtract 5 from each side - 5 - 5 = 3b + 5 - 5 - 10 = 3b divide both sides integers by 3 - 10/3 = (3/3)b - 10/3 = b ---------------------check in original equation ( change whole numbers to fractions of common denominations ) 12(-10/3) - 15/3 = 15(-10/3) + 15/3 - 120/3 - 15/3 = - 150/3 + 15/3 - 45 = - 45 checks
What is the answer to this equation 5a plus 3b plus 9b-10a?
It is not an equation but an algebraic expression that can be simplified to: 12b-5a
How do you Factor b12 plus 8?
Do you mean...? 12b + 8 4(3b + 2) ============( if you meant b12, then there is no factoring possible )
What is the group number for Lanthanides and Actinides?
Rare Earth elements or lanthanides are placed in the period 6 of the periodic table of Mendeleev. Actinoids are placed in the period 7 of the periodic table of Mendeleev.
6b squared minus 3b divided by 3b?
6b^2 - 3b / 3b 6b^2 - 1 or ( 6b^2 - 3b) / 3b = 2b - 1 Or (6b^2 - 3b ) / 3b = 3b(2b - ) / 3b = 2b - 1
What is 3b squared minus 3b?
3b2 - 3b = 3b(b - 1)
