What are the actinides in the Periodic Table of Elements?
The actinide series is a group of elements in the periodic table that includes actinium, thorium, uranium, and all elements from atomic number 89 (actinium) to 103 (lawrencium). These elements are all radioactive and have similar chemical properties.
Elements across a series have same number of?
Elements across a series have the same number of attributes or characteristics.
What are the series or period of the periodic table?
The elements in the horizontal rows are called periods.
What is a period or series?
Periods and series are used when grouping elements. Elements are listed in rows, as periods, on the periodic table so that each is grouped with others with similar properties.
Are radioactive substances the last period of elements (at the bottom of the chart)?
Radioactive substances are not exclusive to the last period of elements on the periodic table, but many of the heaviest elements, particularly those in the actinide and transactinide series, are radioactive. These elements, found at the bottom of the periodic table, typically have unstable nuclei that decay over time. However, there are also radioactive isotopes of lighter elements scattered throughout the periodic table. Thus, while many radioactive elements are at the bottom, not all radioactive substances belong to this category.
Is actinide considered a synthetic element?
Actinide is not an element, but is a series of elements. Of the actinide series of elements, all except actinium, thorium, protactinium, and uranium are considered to be synthetic elements because they are not found in nature in appreciable amounts.
What element does plutonium belong to?
Plutonium is a member of the actinides group.
What is a period or series on the periodic table?
A period on the periodic table is a horizontal row that represents the number of electron shells an atom has. A series on the periodic table refers to a group of elements that share similar chemical properties, such as the lanthanide and actinide series.
Which the element uranium belong to?
The period that Uranium is found in is Period 7 of the Periodic Table.There are only 7 periods in the periodic table...
What family does fermium belong to?
Fermium is a member of the actinides group.
What period does thorium belong in?
Thorium is a member of the actinoids family, period 7 in the periodic table of Mendeleev. The half life of 232Th is 1,405.1010 years.
What is lanthanids?
Lanthanoids is a series of 14 elements starting after lenthanum 57 and it belongs to the 6 period and fblock of the periodic table.
