To what does the term periodic in periodic table refer?
Periodic means reoccuring. On the periodic table, periodic refers to the elements in each group having some of the same simularities and some of the same properties.
What is a group on a periodic table?
A vertical column on the Periodic table on the periodic table is called group. There are 18 groups on the table. These groups are also referred to as families. Each element in a group has the same number of valence electrons and, therefore, similar chemical properties (there are some exceptions though).
What is meant by the Periodic Table?
A table in which properties of elements are repeated after some interval.
How does the arrangement of the periodic table compare to some card games?
The groupings in the periodic table have some simalarities with the card game solitare. All the elements with similar properties are grouped in a vertical group, just as in solitare all cards of the same suit are arranged in a vertical group.
Do arsenic and nitrogen have similar properties?
Arsenic and nitrogen are members of the same group of the periodic table of Mendeleev - group 15 (pnictides); the have have some similar chemical properties but the differences are also very important.
What two elements in the periodic table have similar properties?
element in a group exibhit more or less same properties some of them have more things and some have less as they are dependent on the valency in the outermst shell of the elctrons so that they acn become reactive ,metal non metals etc
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
How do one recognize a periodic trend on the periodic table?
Studying physical and chemical properties of chemical elements it is possible to recognize some trends in the periodic table.
What properties does rutherfordium possess to classify as a metal?
- Rutherfordium is in the group 4 of the periodic table of Mendeleev - Calculation of some chemical and physical properties - Experimantal chemistry: halides of Rf, etc.
What are some ways that elements are arranged on the periodic table of elements?
Mendeleev arranged the elements in a table in the increasing order of atomic masses and repeating periodic properties. In the modern long-form of periodic table, the elements are arranged in the increasing order of atomic number and repeating periodic properties.
In the periodic table what is meant by the term group?
A vertical column on the Periodic table on the periodic table is called group. There are 18 groups on the table. These groups are also referred to as families. Each element in a group has the same number of valence electrons and, therefore, similar chemical properties (there are some exceptions though).
What are some good questions about the periodic table?
Some good questions about periodic table: where are metalloids placed? why group 18 elements are inactive? How many groups and periods are in periodic table? How reactivity changes across and down the group?
