Why do elements on the right side of the periodic table?

Elements further right on the period table, on the other hand, have higher effective nuclear charges and stabilize electrons more effectively, leading to localized covalent bonding and the formation of molecules (vs. the ionic bonding and crystal lattices of metals).

What is Group 1B 8B on the periodic table?

The transition elements get grouped together as the “B” elements, or groups #1B – 8B. Helium is different from all of the other elements. It can only have two electrons in its outer shell. Even though it only has two, it is still grouped with elements that have eight (inert gases).

What is the right side of the periodic table?

NONMETALS
Elements on the right side of the periodic table are NONMETALS. The staggered stair step on the periodic table divides the metals from the nonmetals. Metalloids are located on the stair step.

Why are elements on the right side of the periodic table smaller?

As the elements on the right have more electrons on its valence shell they are attracted more by the nucleus and thus causes a smaller size of the element. So the more you go from left to right in a period of periodic table the lesser the element’s atoms are in size.

Why are Group B called transition metals?

Because they are all metals, the transition elements are often called the transition metals. As a group, they display typical metallic properties and are less reactive than the metals in Groups 1 and 2. Some of the more familiar ones are so unreactive that they can be found in nature in their free, or uncombined state.

What element is in group 1b Period 4?

The period 4 transition metals are scandium (Sc), titanium (Ti), vanadium (V), chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), copper (Cu), and zinc (Zn)….The Transition Metals.

	4
1A	K
2A	Ca

4A	Ge

Why is zinc +2?

Zinc can only form only 2+ (positively charged cations) ions mainly because it has the ability to lose or shed the two electrons in its 4s subshell (outermost shell) yielding a bare zinc ion with the electronic configuration [Ar]3d10.

Which element is in group 3B and in Period 5?

The period 5 transition metals are yttrium (Y), zirconium (Zr), niobium (Nb), molybdenum (Mo), technetium (Tc), ruthenium (Ru), rhodium (Rh), palladium (Pd), silver (Ag), and cadmium (Cd)….The Transition Metals.

	3B
	4B

Which element is in group 17 Period 2?

The halogen elements are the six elements in Group 17 of the periodic table. Group 17 occupies the second column from the right in the periodic table and contains fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts).

What is the p-block of the periodic table?

p-block is group 3A to 8A These are the representative elements or main group elements d-block is group 3B to 2B (look at the periodic table above because the numbers are not sequential) These are the transition metals f-block is located below the main table

How are the elements in the periodic table numbered?

Except for VIIIB, which covers three families of elements (8, 9 and 10 of the modern numbering system), groups IB through VIIB are numbered according to their expected maximum valence. For example, elements in Gr In old-style periodic tables, there are two sets of groups numbered I through VIII (typically using Roman numerals).

Why did the B groups go from 3B to 1B to 2B?

The B groups had to go 3B-8B, and then 1B to 2B. This is because the metals in the first transition metal group, Sc-Y-La, each had three valence electrons i.e. d¹s² hence group 3B. When you got to Cu-Ag-Au, the d sub-shell was full i.e. d¹⁰s¹. So they became group 1B, and the next column Zn-Cd-Hg i.e.

What is the electron configuration of the Group 3b elements?

The Group 3B elements (Group 3 in the IUPAC designation) usually have electron configuration (n -1) d1 ns2. In most periodic tables, lanthanum and actinium are considered to be a part of Group 3B, but in others lanthanum and actinium are considered part of the inner transition elements, leaving lutetium and lawrencium in Group 3B instead.
