That element would be Scandium. It's abbreviation is Sc it was discovered in 1879. It has a density of 2985 kilograms per cubic meter.
they don't fall in one group they are Metalloids non-metals metals
It is a solid at that temp.
you can write billion for short like 1b,2b,3b...and so on
They are called groups. The classic form indicates the 18 groups as 1A, 2A, 3B, 4B, 5B, 6B, 7B, three columns as 8B, 1B, 2B, 3A, 4A, 5A, 6A, 7A, and 8A (or 0). The IUPAC renumbered the groups as simply 1 to 18 in 1990. (see related link)
groups 3 to 7 (IUPAC -- IIIB-VIIB or IIIA-VIIA earlier systems) are called early transition metals because they form the first half of the transition series. This means, for example, that their maximum valency, expressed in their oxy-acids and salts (titanates, vanadates, chromates, and permanganates) matches their group number, that their complexes are slow to react, etc. This contrasts with the late transition metals (IUPAC groups 8 to 12) which tend to have a maximum valency of 2 or 3, and fast reacting complexes.
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^2 - 3b / 3b 6b^2 - 1 or ( 6b^2 - 3b) / 3b = 2b - 1 Or (6b^2 - 3b ) / 3b = 3b(2b - ) / 3b = 2b - 1
so let's group and then factor ab+2a+3b+6= (ab+2a)+(3b+6)= a(b+2)+3(b+2)= (a+3)(b+2) and that is our final answer! Doctor Chuck
Since 3b is a factor of 9b, it is automatically the GCF.
-2b + 7 -3b = 2 -2b +7 -3b +2b = 2 + 2b 7 -3b + 3b = 2 + 2b +3b 7-2 = 2-2 + 2b + 3b 5 = 5b 1 = b
a = 3b - c a + c = 3b - c + c a + c = 3b (a + c)/3 = 3b/3 ( a + c ) / 3 = b Do your homework.
If 3b = 39 thenb = 39/3b = 13.
The group 3B to 12B elements are known as transition metals. They are characterized by their ability to form complex ions with varying oxidation states and exhibit typical metallic properties such as conductivity, malleability, and ductility.
10ax-3b = 7
3b-8b = -5
3b
3b+6b=9b
