A mnemonic can be anything you create to help you remember the letters. Here are some examples -- you can make your own Silly Sentence to remember!
Actinides:
Although theorists prefer unusual new proofs, able chemists believe careful experiments find more new laws.
Lanthanides:
Later, Chemists Posed New Problems, So Experiments Greeted Tired Drudges Helping Enscribe Their Yearly Log
What else can I help you with?
What is the difference between lanthanides and actinides?
Wht is the difference between Lanthanides and Actinides?
Do actinides and lanthanides lose electrons when combining?
Actinides and lanthanides lose electrons and form cations.
What is the group number for Lanthanides and Actinides?
Rare Earth elements or lanthanides are placed in the period 6 of the periodic table of Mendeleev. Actinoids are placed in the period 7 of the periodic table of Mendeleev.
The lanthanides and actinides are known as?
Element groups
What about the complex formation ability of lanthanides as campared to actinides?
describe the complex formation by lanthanides?
How variable are the densities of the lanthanides of the lanthanides compared to the densities of the actinides?
The densities of the lanthanides generally have less variability compared to the densities of the actinides. This is because the lanthanides are more similar in size and electronic structure, leading to more consistent densities. In contrast, the actinides exhibit larger variations in density due to differences in atomic structure and electron configurations.
Why are lanthanides in period six and actinides in period 7?
Lanthanides and actinides occupy period 6 and 7, respectively, due to their electron configurations. Lanthanides have their outermost electrons in the 5d sublevel, which fills in period 6, while actinides have their outermost electrons in the 5f sublevel, which fills in period 7. This results in their placement in these periods of the periodic table.
Where are landthanides and actinides actinides placed in the periodic table?
Lanthanides and Actinides are placed separately as the properties of these elements is quite different from the elements in periodic table.
How many lanthanides and actinides are there?
There are 15 lanthanides (from lanthanum to lutetium) and 15 actinides (from actinium to lawrencium) in the periodic table. These elements belong to the f-block of the periodic table and have unique properties due to their electron configurations.
What two elements are shown at the bottom of the periodic table?
Lanthanides and Actinides.
What elements on the periodic table is a radioactive element?
Lanthanides and Actinides probably
What are properties of f block elements?
they are of two types lanthanides and actinides
