What statement describes the periodic law?

Answer 1

the periodic law states that the repeating chemical and physical properties of elements change periodically with the elements atomic number.

what ever that means (lol)

Answer 2

Depending on what level of facts you need to go to, you could try any of these: http://www.chem4kids.com/files/elem_intro.html http://www.webelements.com/ http://ull.chemistry.uakron.edu/genobc/periodic/ http://environmentalchemistry.com/yogi/periodic/ http://www.rsc.org/chemsoc/visualelements//pages/overview.html

Answer 3

1. Elements are arranged by their atomic number, the number of protons they have.

2. Typically, each family or group has the same number of valence electrons.

3. Group 1 is the Alkali Metals.

4. Group 2 is the Alkaline Earth Metals.

5. Group 18 is the Noble Gases.

6. All elements in Group 18 have an octet of electrons, which is a complete outer shell of 8 electrons, except for Helium (He) which only needs 2.

7. Atomic radius increases as you go down the periodic table.

8. Metals are found to the left of the staircase, nonmetals to the right, and metalloids are located on the staircase.

9. Group 1, the alkali earth metals, are the most reactive.

10. Group 18, the noble gases, are the most stable elements.

Answer 4

The periodic law states that the physical and chemical properties of elements are periodic functions of their atomic numbers. This means that elements with similar properties appear at regular intervals when the elements are arranged in order of increasing atomic number.

Answer 5

The periodic law states that many of the physical and chemical properties of the elements tend to recur in a systematic manner. This is with the atomic number increasing.

Answer 6

A Periodic Table is made up of chemical elements. They are all arranged in order of atomic number, usually in rows.

Answer 7

elements in the same group have similar chemical properties
elments in the same group have similar chemical properties
