What determines an elements chemical properties?
Chemical properties of an element determine by the number of electron
What factors determine an element's chemical properties?
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.
The number and arrangement of electrons in the outer energy level determains the atoms what?
The number and arrangement of electrons in atoms of an element determine the chemical properties of the element.
Does atomic no of elements determine their 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
What part of an element determines its ability to combine with other elements?
The number of valence electrons an element atom contains will determine its chemical properties.
Which subatomic particle determines the behavior of an element?
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
What determines an elements property?
Chemical properties of an element determine by the number of electron
The definition of atomic number?
The number of protons in the nucleus of an atom, which determines the chemical properties of an element and its place in the periodic table.
Why do istopes have different physical properties but same 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.
What is the atomic numberHow is it used to distinguish one element from another?
The number of protons in the nucleus of an atom, which determines the chemical properties of an element and its place in the periodic table
The is determined by the number of protons in an atom?
The number of protons in the nucleus of an atom is known as the atomic number, which determines the chemical element, essentially different numbers of protons mean change the element you are looking at and hence the properties and reactions of that element.
Why would you expect lithium and sulfur to have different chemical and physical properties?
Because they both have a different number of valence electrons in their outer shells, and that is what determines the properties of the element.
