elements in the halogen family react easily with other elements whose atoms can give up electrons.alkali metals lose one electron they are left with 0 valence electrons and they become more chemically stable
The main three properties of the metals are malleability (you can shape it easily), ductility (you can turn it into a wire) and conductivity (it will carry heat and electricity very well).
Co,Ni makes cations of different colours. So they make easily identifiable compounds. Elements in the d group make colourful cations.
Any element in the alkali metal group would have similar chemical properties, for example they all react easily to water.
by creating the periodic table. With the atomic number they all ready managed to sort them into property like elements so when they found new ones they could easily sort them because of the properties of the others
Yes, each element has specific physical properties.
Periodic table is a tool to study elements. Their properties can be studied easily.
By knowing mass number of the elements we can easily find out the number of neutrons presen in the nuclei.Physical properties of elements somewhat depends on mass number.
you can easily compare to different subjects

Price comparison websites allow you to compare different insurance quotes from many different companies in one place. These websites allow to compare different types of insurance such as car insurance, home insurance and travel insurance.
atoms have symbols so that the atoms of different elements can be distinguished easily.
Co,Ni makes cations of different colours. So they make easily identifiable compounds. Elements in the d group make colourful cations.
Some places like www.doorson-line.com is a good place to look. They have many different type of garage doors and are easily able to compare too. They also have many different types to choose from.
noble gases really are just that: noble. they dont react to things easily. halogens on the other hand, do react extremely easily. that is one of the main differences between the two.
