beacause they are rare metals and they help Basketball players
The rare earth metals are located in the lanthanide series of the periodic table, which is found at the bottom of the table.
The most massive elements on the periodic table are generally found at the bottom right, where the actinides and transactinides are located. These elements have the highest atomic numbers and are among the heaviest known elements.
On the left side (the first 12 columns + the bottom four in the 13th column+the bottom two in the 14th column+the bottom one in the 15th column)
The periodic table of elements is a chart that organizes the elements and emphasizes their shared traits and commonalities. All the known elements and their atomic number are on the periodic table.
The North America Convention Periodic Table is a variant of the traditional periodic table that places the lanthanides and actinides separately at the bottom of the table, rather than within the main body of the table. This arrangement is done to reduce the width of the table and make it easier to read.
because they are man made.
The are the lanthanoids and actinoids elements.
They are lanthanides and actinides. They have different chemical properties , hence they are placed separately.
The two rows of metals that appear at the bottom of the periodic table are the lanthanides and actinides. They are known as the inner transition metals and are placed below the main body of the periodic table to keep the table size manageable.
The two sets of elements found below the Periodic Table are the Lanthanides and the Actinides, which are also known as the Inner Transition Elements. They are placed separately at the bottom of the Periodic Table to keep the table compact and organized.
These elements are termed as 'lanthanides' and 'actinides' have certain different characteristics that cannot be fitted into modern periodic table,hence they are placed at the bottom.
The rare earth metals are located in the lanthanide series of the periodic table, which is found at the bottom of the table.
at the bottom of tne first group.
Yes, the heaviest atoms, which have the most protons and electrons, are found towards the bottom of the periodic table in the actinide and transactinide series. These elements have high atomic numbers and are generally unstable and radioactive.
The most massive elements on the periodic table are generally found at the bottom right, where the actinides and transactinides are located. These elements have the highest atomic numbers and are among the heaviest known elements.
The vertical columns of the periodic table are arranged to contain elements that have similar chemical and physical properties.The two rows at the bottom (called the Lanthanide and Actinide series) are elements that would all fit into group IIIB, in periods (horizontal rows) 6 and 7. since there is only one spot on the chart for all the elements in each series, they are listed separately at the bottom of the table.
The lanthanides and actinides are located in the f-block of the periodic table. The lanthanides are found in the sixth period, spanning from cerium (Ce, atomic number 58) to lutetium (Lu, atomic number 71). The actinides are in the seventh period, ranging from actinium (Ac, atomic number 89) to lawrencium (Lr, atomic number 103). Both series are typically displayed separately at the bottom of the periodic table to maintain its overall structure.
