What is the lanthanide contraction?
The decrease in size of elements in the lanthanide series with increase in atomic number due to the poor screening power of the 'f' orbital is known as lanthanide contraction. This effect is also found in transition series where it is due to imperfect sheilding of 'd' orbitals.
What family does the element actinium belong to?
Actinium is the first member of the actinoids family.Actinium is a solid, inner transition metal, radioactive, very rare.
What group does Cytosine and Thymine belong to?
They belong to the pyrimidine group.
What kingdom do mammals belong to?
mammals belong to the animalia kingdom
What phylum do eel belong to?
The same phylum you belong to! Chordata.
Which really belong to group iii lanthanum and actinium or lutetium and lawrencium?
Lanthanum and lutetium are members of the lanthanoids family.Actinium and lawrencium are members of the actinoids family.
Lanthanum does not belong to lanthanide series actinium does not belong to anthanide series why?
After the IUPAC nomenclature lanthanum is a lanthanoid and actinium is an actinoid.
What family does the element lutetium belong in?
Lutetium is one of the first inner transition series metals, sometimes called "lanthanides" because all of them have chemistry very similar to that of lanthanum, the first member of the series.
What family does the actinium belong to?
Actinium is the first member of the actinoids family.
What is the lanthanide contraction?
The decrease in size of elements in the lanthanide series with increase in atomic number due to the poor screening power of the 'f' orbital is known as lanthanide contraction. This effect is also found in transition series where it is due to imperfect sheilding of 'd' orbitals.
What is the central block of the periodic table called?
Lanthanides and ActinidesThey actually belong INSIDE the main table (not below it) after Lanthanum and Actinium, but are pulled out for formatting purposes to prevent the table from getting too wide.
What elements belong to the f-block of the periodic table?
All the Actinoids and Lanthanoids compose the f-block of the Periodic Table.\The actinoids are: Actinium (Ac), Thorium (Th), Protactinium(Pa), Uranium(U), Neptunium (Np), Plutonium (Pu), Americium (Am), Curium (Cu), Berkelium (Bk), Californium (Cf), Einsteinium (Es), Fermium (Fm), Medelevium (Md), Nobelium (No) and Lawrencium (Lr).The lanthenoids are: Lanthanum (La), Cerium (Ce), Praseodymium (Pr), Neodymium (Nd), Promethium (Pm), Samarium (Sm), Europium (Eu), Gadolinium (Gd), Terbium (Tb), Dysprosium (Dy), Holmium (Ho), Erbium (Er), Thulium (Tm), Ytterbium (Yb), and Lutetium (Lu).
What family does the element actinium belong to?
Actinium is the first member of the actinoids family.Actinium is a solid, inner transition metal, radioactive, very rare.
What family does lanthanum belong to?
promethium
What block are the transition metals found in?
The inner transition metals belong to the f block on the periodic table. Examples of f block elements are cerium, gadolinium, terbium and lutetium.
What family does Curium belong to on the periodic table?
curium belongs to the actinide series on the periodic table. The actinides are a group of elements in the seventh period of the periodic table, and they follow actinium (Ac) and precede lawrencium (Lr). The actinide series includes elements with atomic numbers from 89 to 103. Curium has the atomic number 96 and is represented by the symbol Cm.
