Chemical properties of an element determine by the number of electron
Electrons have the essential role.
families of elements with similar chemical properties are called groups.
The electron shell is the source of an element's chemical properties and the moderator of chemical reactions; the electron shell depends on the protons that constitute the atom
It is helpful to organize things by characteristics because you can tell that certain elements are similar. For example if you knew nothing about the chemical or physical properties of (Rb) Rubidium, you could guess it has properties similar to (Cs) Cesium since they are in the same group. The common "Periodic Table" has many interesting forms. Search: "periodic table"
Physical properties use your senses and chemical properties are when you mix two chemicals together.
The electron configurations of the elements in each main group are regular and consistent:the elements in each group have the same number of valence electrons.
The family/group where they belong.
Electrons.
No. The properties of elements are determined by the number of protons, which in turn determines the number of electrons.
Elements in same column have same number of outermost electrons. It determines chemical properties.
It determines which element, which all have their own properties so yes. The mass number just determines the isotope which only affects their stability
There are specific factors that can contribute to a the properties of chemical elements. Some of these factors include the amount of valance electrons in the element.
Elements are distinguished by their atomic number, which is the number of protons in the nucleus of an atom. The element's atomic number determines its chemical properties.
Chemical properties of an element determine by the number of electron
The valence electrons
The elements that compose it and the arrangement of its atoms
These elements have similar chemical and physical properties.
the properties of elements are determined by the structures of their atoms.
