There is no fully objective answer to this question. Many chemists would consider that two lanthanide elements with atomic numbers differing by only one would be likely to qualify. Another possibility is the pair zirconium and hafnium. These are very similar in most chemical characteristics but differ greatly in electron capture tendencies in nuclear reactors.
Those that are in the same vertical column tend to have similar properties.
Elements in the same group have same number of valence electrons and hence have similar chemical and physical properties.
silver, gold, copper have similar properties
Elements belonging to the same group in the Periodic Table have similar properties. For example, the first group, that is, alkali metals, all have similar properties.
Elements grouped in the same column exhibit similar properties.
Those in the same column of the periodic table.
yes for example alkali metals
Elements with similar physical and chemical properties are located in a group.
Elements of same group have the same number of valence electrons and hence have similar properties.
Generally the properties are different.
NO
The elements in a group have the similar chemical properties dueto presence of same no of electrons in their outermost shell but they differ physically because physical properties are related to their atomic sizes from top to bottom in a group atomic size increases so their physical properties also differ.
These elements have similar chemical and physical properties.
Sulphur and helium have entirely different properties. Sulphur has properties similar to group 16 elements. Helium has properties similar to group 18 elements.
Elements in the same group (column) have the same properties. All the elements in group one have similar properties. All the elements in group two have similar properties. And so on...
The elements in the same groups usually do. Elements in the same group have same number of valence electrons and hence have similar chemical and physical properties.
Elements in the same group have similar properties. The groups are made according to the properties of elements. Elements in a group have an equal number of valence electrons.
Elements with similar physical and chemical properties are located in a group.
families of elements with similar chemical properties are called groups.
They have the same number of valence electrons and so have similar reactivity and similar properties.
Elements of same group have the same number of valence electrons and hence have similar properties.
Elements in the same family-assuming family means classifications such as non-metals, metals-have similar properties.
a group of elements that have similar properties are arranged one on top of the other on the periodic table. These groups are also called families
They can, however in Groups the properties are much more similar.
