It has similar properties to the element with proton number 20, which is calcium.

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.
Isotopes of the same element differ in the number of neutrons. Isotopes have different physical properties but similar chemical properties.
Iodine and chlorine have very similar chemical properties because they are in the same chemical family (go see a periodic table). They are both halogens (so they have the same valence electrons).
the number of electrons that fill the outer shell
All of the isotopes of an element have the same chemical properties because they all have the same number of protons and the same number of electrons in their valence shells.
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.
Chemical properties of a element is governed by ELECTRONIC CONFIGURATION of that element. As isotopes of same element have identical electronic configurations, their chemical properties are same.
Chemical reactions involve electrons - not protons or neutrons. All isotopes of the same element have an identical number of electrons (just the number of neutrons differs) and hence the chemical properties are identical/very similar.
Same number of protons; identical or very similar chemical properties.
They have similar chemical properties because isotopes of an element have the same number of electrons as an atom of that element. The electron arrangement is the same owing to same chemical properties. However they have different numbers of neutrons, which affects the mass number. Mass number determines the physical properties such as boiling/melting/density etc.

Isotopes of an element have same number of protons and different number of neutrons. Hence similar in chemical properties and different in physical properties.
by having the same number of protons and electrons and so still have the same chemical properties and physical properties with the exception of being somewhat denser.All of the isotopes of an element contain the same number of protons. They differ only in the number of neutrons.The number of electrons is an ionization state issue, and does not affect isotopic identity.
The two elements that have the most similar chemical properties to arsenic are Phosphorus (P) and Antimony (Sb).
The chemical properties of an element depend on its electron configuration, which is in turn determined by the number of protons. Isotopes of an element differ in the number of neutrons, which, being neutral, have not influence on chemical properties.
As I understand it, since they have the same number of protons, they tend to attract the same number of electrons. All neutral atoms of the same elements will have the same number of electrons. This gives them similar chemical properties, since the chemical properties are, to a great extent, determined by the outermost electrons.
Chemical properties of an element determine by the number of electron
