Begin by entering your name and date at the top of the form. This personalizes your document and keeps track of submissions.
For the first section, identify the groups of elements on the periodic table. Write the corresponding letter next to each group listed (e.g., carbon family, alkaline earth metals).
In the next part, explain each part of sodium's electron configuration in the provided spaces. Use your knowledge from Section 5-2 to articulate your understanding clearly.
Continue by classifying elements as metal (M), nonmetal (NM), or semimetal (SM) for questions 19 through 23. Ensure accuracy based on periodic table knowledge.
Finally, answer questions about periodic table information and properties distinguishing metals from nonmetals in the designated areas. Provide thorough explanations for clarity.

What are the differences between group 1 and group 2 elements?

The group one and 2 differ from one another looking at the number of electrons in their outermost orbital. The key distinction between group one and group 2 parts is that all group 1 parts have mismatched electrons in their outermost orbital, whereas group 2 parts have paired electrons in their outermost orbital.

What makes group 2 cations different from the group 1 cations?

Please note, some elements are capable of having a range of electrical charges, and therefore form different ions. Group I A (1) elements form cations with +1 charge. Group II A (2) elements form cations with +2 charge. Groups III B through II B (3 12) are transition metals.

What is the difference between group 1A and 2A?

Group 1A is also known as the alkali metals. Although most metals tend to be very hard, these metals are actually soft and can be easily cut. Group 2A is also called the alkaline earth metals. Once again, because of their similarities in electron configurations, these elements have similar properties to each other.

What information is contained in each of the 109 squares?

Each square of the periodic table gives particular information about the atoms of an element. The number at the top of the square is the atomic number, which is the number of protons in the nucleus of an atom of that element. The chemical symbol is an abbreviation for the elements name. It contains one or two letters.

What is the group 2 period 2 on the periodic table?

Group 2 elements are located on the left side of the periodic table and are often referred to as alkaline earth metals because they form an alkaline solution with water, are found naturally in the earth, and are metals. This group includes beryllium, magnesium, calcium, strontium, barium, and radium.

What is the difference between Type 1 and Type 2 elements?

There are two main types of ionic compound with different naming rules for each; Type I: compounds containing cations of main group elements and Type II: compounds containing cations of variable charge (generally transition metals).
