If all the elements in a group are the same what is the point of so many elements?
If all of the elements in a group were the same, they would be the same element and wouldn't be in groups. You are slightly mislead; the elements in the groups are similar, not the same.
correct up above... each element has a different amount of protons changing its elemental properties. they are only catagorized in the same group because they have the same amount of valence electrons
extra info: the mass of the element atom is based on the weight of the Protons and Neutrons together only, not the electrons. This is because the exact mass of an electron is not yet fully known because they move so fast in the outer shell. it is estimated to be very very very small though, and due to this, the mass wouldn't change any if the electrons were added in or not... so there ya go buddy :)
What else can I help you with?
Elements that have many similar properties belong to the same what?
Elements that have many similar properties belong to the same group on the periodic table. Each group shares similar chemical characteristics due to their same outer electron configuration.
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.
Where are elements with the same number of valence electrons?
Elements with the same number of valence electrons are found in the same group or column of the periodic table. This is because elements in the same group have the same number of valence electrons, which determines their chemical properties. For example, all elements in group 1 have 1 valence electron.
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.
Elements that have many similar properties belong to the same what?
Elements that have many similar properties belong to the same group on the periodic table. Each group shares similar chemical characteristics due to their same outer electron configuration.
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.
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 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 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.
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.
Where are elements with the same number of valence electrons?
Elements with the same number of valence electrons are found in the same group or column of the periodic table. This is because elements in the same group have the same number of valence electrons, which determines their chemical properties. For example, all elements in group 1 have 1 valence electron.
Do elements in the same group have the same physical or chemical properties?
Elements in the same group have similar properties as they have the same number of valence electrons.
How many elements contain the same number of outer electrons as sodium?
Elements in the same group as sodium (Group 1) all contain the same number of outer electrons, which is one. Therefore, there are six elements in the same group as sodium: lithium, potassium, rubidium, cesium, francium, and hydrogen.
