Question

i need someone to list which elements belong in the alakali metals, alkali earth metals, halogens, lanthanides, and actinides.
thanks.
science class isn't helping much.

Answer 1

You will need to do your own homework. All of this information is in your text book.

Answer 2

As the last poster indicated, some of the classifications you've indicated are groups, i.e. columns on the periodic table. Some of them are periods - rows - or parts of periods. The Lanthanide and Actinide series - rows - will be listed specifically on any decent table. The groups are a little trickier. While they may be listed on a table, they probably won't be. All you have to do is determine to which group a particular element belongs, then any element in the same column is a part of that group. For instance, sodium is an alkali metal, so anything in the same column as sodium is also an alkali metal.

That should be enough to get you there with a little research. Good luck.

Answer 3

The alkali metals are the ones all way one on the left. The alkali earth metals are the ones right next to the akali metals. The noble gases are all the way on the right hand side and the halogens are right next to the noble gases.
The lanthanides and actinides are the 2 rows at the bottom.

Answer 4

There are 18 columns called groups on the periodic table. COLUMNS, going vertically. You'll have to look up which is which on your own, but group 18 is the noble gases. Each one of the categories you listed are names of groups, but I will not pull out my table and do it all for you. Just go onto wikipedia or something.

Answer 5

Try looking up DIMITRI MENDELEEV is Your library. He was after all the person who first devised the periodic table way back in 1869.

Answer 6

Alkali earth- 2nd row
halogens- last row
