Mention any four rational numbers which are less than 5 Hey arizoo, steph, iman
Anyone you all online?​

4.759, -1000, 1/597, and  -1.245

Explanation:

A rational number is any number that DOES NOT repeats infinitly, contains a symbol, or have a square root.

This means any fraction, any postive or negative number, and any decimal can be a rational number.

So four rational numbers less than 5 could be:

4.759

-1000

1/597

-1.245

Hope this helps! :D

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
