Elements in group 1 have a lower number of electrons with respect to the other elements in the same period.
those elements are in the same 'family' or 'group'
hydrogenhydrogen------------------------------------------------------Put the following elements in order, with the element having the most valence electrons at the top of your list and the element with the fewest valence electrons at the bottom.NEONCHLORINESULFURNITROGENSILICONBORONCALCIUMSODIUM
One; for example the thermal decomposition of a compound.
In a neutral atom the number of electrons is equal to the number of protons; and the number of protons is the label of a chemical element.
Chemical properties depend on electrons.Isotopes of an element have the same number of electrons and different number of neutrons.So they have similar chemical properties and different physical properties.
similar chemical properties and characteristics
They have the same amount of valance electrons.
those elements are in the same 'family' or 'group'
Because they have the same number of valence electrons, which are the primary determinants of chemical reactivity.

Each family has different number of valence electrons. The chemical properties of each family is also different.
Elements in the same family, or group will contain the same number of valence electrons and have many similar characteristics.
The chemical behavior is determined largely by the number of valence electrons.
One; for example the thermal decomposition of a compound.
Electrons determine the chemical properties.
Electrons determine the chemical properties of an atom.
Group number describes the number of valence electrons. It helps in estimating chemical properties of that element.For example-group-1 elements have 1 valence electronThe group number of an element is equal to the number of valence electrons. The number of valence electrons is responsible for the chemical properties. So the chemical properties of the element can be determined by the group number.
