How is boron different from other elements in group 13?
because boron is the first and main element in that group.
What elements are there in freon 13?
Freon-13 is CClF3 and has a total of 5 atoms (1 carbon, 1 chlorine and 3 fluorine atoms)
Can any of the 112 known elements combine to form a mineral?
No. There are 13 elements that are either noble gases or are unstable in nature.
How many valence electrons does an atom have from group 16?
Atoms of elements in Groups 13-18 have 10 fewer valence electrons than their groups numbers.However , helium atoms have only 2 valence electrons.
Which period does aluminum belong on the periodic table?
On the periodic table, aluminum belongs to Period 3. Aluminum also belongs to Group 13. On this table, periods are the horizontal rows of elements that run from left to right. Groups are the vertical columns of elements.
Elements in groups 3-13 are called?
Transition metals
What are the groups of elements called that have very regular electron configuration They are considered the representative elements?
Groups 1, 2, and 13-18.
What are the two main groups?
There are eight groups that make up the main group elements. They are groups 1, 2, and 13 - 18. They are also called the representative elements.
What are in the main group of elements?
Groups 1, 2, and 13 - 18 are the main group elements, also called the representative elements.
Where are the representative elements on the periodic table?
-melting/freezing point -boiling point -density -reactivity with acid -flammability -solubility
What are representatives elements?
elements from group1-2 ,13-18 are called representative elements. Those from 3-12 form the transition elements!
Why are the groups 13-18 called p-block elements?
it is the name of the electron subshell that it ends in.
What are the groups below the main group elements on the periodic table called?
3d-block elements or tranformation elements and 4f-block elements or lanthanides and actinides
Why are elements in the tall columns in the periodic table called representative elements?
Conventionally representative elements are called the chemical elements from the groups 1,2, 13-18. These elements haven't generally variable valencies. The transitions metals are not representative elements.
What is Group A called in periodic table?
In the older periodic table, each group was divided into A & B sub-groups. The only problem with that was that there were two different conventions about which elements were labelled "A" and which were labelled "B". Groups 1 & 2 were clearly 'A' (elements like sodium and calcium) and 11 & 12 were clearly 'B' (elements like copper and zinc). But groups 3 through 10 were labelled 'A' in one convention and 'B' in another, and the opposite labels were used for groups 13 through 18.With the second labelling convention, groups labelled 'A' were known as 'main group elements', and groups labelled 'B' were 'transition metals', and that is still the case.Thus in the newer IUPAC scheme, groups 1, 2, and 13 through 18 are called 'main group elements'.
Why are the main block elements also called the representative elements?
The representative elements are in the groups 1,2, 13-18; the name is given to make a difference toward transition metals.
Which of the following groups of elements are the main group?
nonmetals, alkali metals, and halogens, among others.To be precise it is elements in IUPAC groups 1,2, and 13 to 18 -- otherwise designated as the "s-block and p-block" elements.
