Periodic table

Who created the early version of the periodic table in 1869?

Why was Mendeleev´s table seen as "clever"?

Which electron shell is closest to the nucleus in an atom?

The elements on the right side of the periodic table are typically:

Non-metal oxides are Acidic

Which group contains one outer electron?

Elements in group 1 are known as:

What does the term "electron configuration" refer to?

Group 0 elements are also know as:

The term "inert" describes Group 0 elements because they:

What is the electronic configuration for Helium (He)?

Which element has the simplest electronic configuration?

The atomic number represents:

Group 0 (Noble gases) are (select one):

What did Mendeleev predict with his table?

Metal oxides are Basic

Which term describe better elements that conduct electricity?

The key factor that determines the chemical properties of an element is the number of:

What is the maximum No. of electrons can the 2nd shell hold?

What is the electronic configuration of Calcium (Ca)?

Noble gases (group 8) are considered unreactive

Elements in the same group have similar:

Elements in Group 1 are most reactive with:

Metal oxides which dissolve will form solutions with:

Group 0 elements are commonly referred to as:

What is the maximum number of electrons in the 1st shell?

Which of these elements is in group 1?

Which element has the electronic configuration 2.8.7?

Which shell fills the electrons first?

In the modern periodic table, elements are arranged in order of increasing:

Group 2 elements have now many electrons in their outer shell?

Why is the outer electron shell particularly important in determining element properties?

Which element has an electronic configuration of 2,8,1?

Which of the following is NOT a property that elements in the same group share?

The outermost electron shell is known as the:

Why are noble gases considered unreactive?

Vertical columns in the periodic table are called:

Group 7 elements, such as chlorine, are also known as:

Atomic number is significant because it equals the number of:

Elements on the left side of the periodic table are generally:

What concept did the gaps in Mendeleev´s table represent?
