Group 1 is known as the alkali metals. Their major characteristic is a reaction with water that ranges from vigorous (Li) to violent (Cs) as you move down the group. This reaction results in alkaline solutions.
They are soft, low density, low melting metals that tarnish rapidly in air.
What else can I help you with?
In periodic table What periodic pattern is repeated in each group?
In the periodic table, each group (or column) exhibits a periodic pattern of similar chemical properties and behaviors among its elements. This similarity arises from the elements having the same number of valence electrons, which influences their reactivity and bonding characteristics. As you move down a group, the elements typically show an increase in atomic size and a decrease in electronegativity and ionization energy. This consistent pattern helps predict the properties of elements within the same group.
What are bridge and typical elements in modern periodic table?
In the modern periodic table, a bridge is a group of elements that connects the main body of the table. These include elements such as lanthanides and actinides. Typical elements are the main group elements found on the left and right sides of the periodic table, and they generally display similar chemical properties within each group.
How did Dmitri Mendeleev discover the periodic table with noble gases?
Dmitri Mendeleev did not discover the noble gases as they were not known at the time he created the periodic table. The noble gases were discovered later by other scientists. Mendeleev's periodic table focused on arranging elements by atomic mass and properties to show periodic trends.
What does the background of the square indicate in the periodic table?
It depends on the key of the periodic table. Usually it signifies the type of element, e.g., alkali metals, nonmetal, noble gases, metalloid, rare eath metals, transition metals. However, it can mean other things.
Explain why hydrogen is not included in group 1 in most versions of the modern periodic table?
Hydrogen is not included in group 1 in most versions of the modern periodic table because it does not exhibit the typical characteristics of alkali metals found in group 1. While hydrogen can lose an electron to form a positive ion like alkali metals, it can also gain an electron to form a negative ion like halogens. This dual behavior makes hydrogen unique and not easily categorized with alkali metals. Therefore, it is often placed separately at the top of the periodic table.

What elements would show similar characteristics to Na?
Na (sodium) belongs to the first group (vertical row) in the periodic table, all of the other elements in this group (row) have similar characteristics to each other. In general, each group has similar characteristics.
How would you find the grams on the periodic table?
The periodic table doesn't show grams; and which grams ?
What is a column called on the periodic chart?
The columns of the periodic table are known as 'groups'. Further, the elements in the same group almost show a same type of chemical behaviour.
What are bridge and typical elements in modern periodic table?
In the modern periodic table, a bridge is a group of elements that connects the main body of the table. These include elements such as lanthanides and actinides. Typical elements are the main group elements found on the left and right sides of the periodic table, and they generally display similar chemical properties within each group.

What does the number at the top of each column in the periodic table mean?
The number at the top of each column in the periodic table is the group number. It indicates the number of valence electrons an element in that column has, which influences its chemical properties. Elements in the same group tend to have similar chemical behavior due to their shared number of valence electrons.
What does the periodic table show us about atoms of various elements?
Periodic table show that elements have properties which are periodic in nature. These properties can be grouped together.
Column or family in the periodic table?
A column in the periodic table is a vertical group of elements that share similar chemical properties. A family in the periodic table refers to a horizontal row of elements with increasing atomic numbers.
Why is hydrogen not included in group 1 in modern periodic table?
Even though hydrogen has a vacant electron in its outer shell, like many of the elements in group 1 of the periodic table, it has unusual properties, e.g. it is a gas at room temperature, whereas the other elements are all solid. As a result, some forms of the periodic table show hydrogen above the rest in the table, in its own special place. However, it is still in group 1
What are two elements that have properties similar to chlorine?
Bromine and iodine are two elements that have properties similar to chlorine. They belong to the same group in the periodic table, known as the halogens, and share characteristics like reactivity and forming salts with metals.
The periodic table is called periodic because the of the elements repeat periodically?
The periodic table is layed out to show "Periodic" chemical properties such as the number of protons in the nucleus of the elemnt, and the number of valence electons it has.
