28

What did Robert Boyle contribute to the development of chemistry?

Published the Sceptical chymist

28

What widespread problem in chemistry did Berzelius solve?

Developed a simple symbolic system to identify the elements

29

List four sources from which elements names are taken.

IDK

30

Which elements are naturally monatomic?

Helium neon argon krypton xenon and radon

31

Describe the composition and arrangement of a buckyball.

IDK

32

State Mendeleev's periodic law.

The properties of the elements vary with their atomic numbers in a periodic way.

33

What feature of Mendeleev's periodic table prompted new discoveries?

It made predictions

34

What problems did Mendeleev's periodic table have? How were these solved?

The elements were not all in similar groups. Changing the arrangement of the rows fixed that.

35

Why does an elements atomic number affect its properties?

The numbers represent the number of electrons in the atom.

36

How can you identify the elements in a family on the periodic table? What do neutral atoms of these elements have in common?

Idk

37

What element in the first column of the periodic table is not one of the alkali metals? What does it have on common with them?

Hydrogen it has one electron

38

How is an elements period related to its electron configuration?

Idk

39

What are two important factors that affect valence electrons and contribute to the chemical and physical properties of elements?

The distance between the valence electrons and the nucleus and the electron arrangement.

40

How does the number of main energy levels in an atom generally affect how tightly it's valence electrons are held by the nucleus?

The higher the energy the farther the electrons are from the nucleus
