They have different numbers of valance electrons...
Period in the periodic table.
Elements of same group have the same number of valence electrons and hence have similar properties.
Elements with same properties are present in same group. They are not present in same period. For example- alkali metals are present in same group.
Yes. Its true that elements with similar properties are found in same group.
In the Periodic Table Of Elements, elements are not necessarily similar under the same period. But, they are similar under the same group. they only have one thing in particular they have the same amounts of shells for the atoms
Across any period, the properties of elements gradually change. This gradual change is called a periodic trend.
no. A period is a row of elements in the periodic table whose properties change gradually and predictably.
Period in the periodic table.
The Periodic table is a representation of all elements grouped in a manner that lists elements with similar properties in columns. Adjacent columns have deceasing or increasing characteristics
They have similar chemical properties.
Periodic means repeating. When Mendeleev was rearranging the elements, he noticed that some of their properties matched with one another about every eight elements. Thus, when the elements are arranged in the rows of the Periodic Table, they also have matching properties in each column.
Elements with same properties are found in same group.They are also called families.
The rows in periodic table are known as periods. The arrangement is such that elements with similar properties fall in the same period.
well, the periodic table is very useful because you have the atomic number, atomic mass, and even the trends across a period or down a group.
Elements of same group have the same number of valence electrons and hence have similar properties.
Elements with same properties are present in same group. They are not present in same period. For example- alkali metals are present in same group.
Yes. Its true that elements with similar properties are found in same group.
