because a group of elements in the Periodic Table behave in a single manner.they have a similar kind of physical properties,i can't surely tell about the chemical properties but in some exceptions these chemical properties are also same.
What else can I help you with?
Why oxygen is placed in group 6?
Oxygen is placed in group 6 (also known as group 16) of the periodic table because it has 6 valence electrons in its outer shell. Elements in the same group tend to have similar chemical properties due to their shared number of valence electrons.
Do elements in the same group have similar atomic numbers?
Elements in the same group have similar chemical properties but not necessarily similar atomic numbers. Elements in the same group have the same number of valence electrons, which determines their reactivity and chemical properties.
What elements did Mendeleev group with lithium in his periodic table?
alkaline metal group(or the group 1 elements, except for hydrogen(H), which is a group 1 element but not an alkali metal) - lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr).
Which two elements are in the same group or family?
According to Chemists, the elements of sodium and chlorine belong to the same atomic family as well as carbon and lead.
What are to two element that have properties similar to those of the element sodium?
Lithium and potassium has same properties as sodium.They are alkali metals.They are placed in group-1.The elements of the same group have same chemical properties. Li and K are the elements above and below Na in the period. So they have same properties as sodium.
Why elements are place in a group?
Elements with similar electron configurations are placed in the same group.
What causes the propertiesof elements in a group to be simalar?
Same number of valence electrons cause same properties. The elements with same properties are grouped together. For example- the alkali metals are placed in group-1
How did Mendeleev discover a pattern of repeating properties in elements?
Mendleef arranged the elements in the increasing order of their atomic masses due to which elements having same properties were placed in the same group and there were few exceptions.
What is special about the elements in the same group?
elements are in the same group since they react similarly to other elements in that group.
What elements occupy the same group in the periodic group?
elements that share the same colum
Elements in a group have-?
Elements in group have same number of valence electrons. They also have same chemical properties.
Are k and calcium in the same family in the periodic table of elements?
K refers to potassium. it is placed in alkali metal family i.e. group 1. Calcium is placed in alkaline earth family i.e group-2.
What do all the same elements have in a group in common?
Same elements of group have same valency. They possess same chemical behaviour.
What do elements in a group have in common?
The elements in the same group have the same number of valence electrons and hence similar chemical and physical properties.
What is similar when elements have the same group?
Elements in the same group have similar physical and chemical properties.
What are elements of a group that has the same number of shells?
The elements in a group do not have the same number of shells, however, the elements in a horizontal row do have the same number of shells.
Do elements in the same group have the same amount of electron clouds?
No, they do not. However, elements in the same group have the same number of valence electrons.
