28
Q

What widespread problem in chemistry did Berzelius solve?

Developed a simple symbolic system to identify the elements

29
Q

List four sources from which elements names are taken.

A

IDK

30
Q

A

Helium neon argon krypton xenon and radon

31
Q

Describe the composition and arrangement of a buckyball.

A

IDK

32
Q

State Mendeleev’s periodic law.

A

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

33
Q

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

A

It made predictions

34
Q

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

A

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

35
Q

Why does an elements atomic number affect its properties?

A

The numbers represent the number of electrons in the atom.

36
Q

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

A

Idk

37
Q

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?

A

Hydrogen it has one electron

38
Q

How is an elements period related to its electron configuration?

A

Idk

39
Q

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

A

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

40
Q

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

A

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