The number of valence electrons in an element is represented by the group number; for example, all elements in group one have one valence electron, all elements in group two have two valence electrons, etc.

Which component of the atom can change its identity to a new element?

Protons determine which element an atom is.


Does an electron determine what element it is?

The number of protons determine which element an atom is and normally the number of electrons is equal to it. Strip an electron off an iron atom and you have an ionised iron atom.


What number of an element can be used to determine the number of electrons in an atom?

The atomic number of an element can be used to determine the number of electrons in an atom. It is equal to the number of protons in the nucleus of an atom, which also corresponds to the number of electrons in a neutral atom.


What elements are contained in a cancer atom?

There is no such thing as a cancer atom as cancer is not an element or even a substance. Cancer is a disease. An atom can belong to only one element and cannot contain others.


What do the protons of the nucleus of an atom determine?

Number of protons or the atomic number of an atom determines what is the element.


What do protons determine about an element?

The protons of an element determine the atomic number, also known as the proton number. Do not confuse this with mass number which is the number of protons and neutrons.


How can you determine the number of electrons in an element?

To determine the number of electrons in an element, you can look at the atomic number of the element on the periodic table. The atomic number represents the number of protons in the nucleus of an atom, which is equal to the number of electrons in a neutral atom.


Is a atom an element?

An atom is an element. Every atom has a certain amount of protons, neutrons and electrons and these are what define which element that atom is.


Atom with 7 protons?

An atom with 7 protons is a nitrogen atom. Protons determine the element of an atom, so an element with 7 protons is always nitrogen, which has the atomic number 7.


Do electrons determine what kind of element an atom is?

Yes, the number of electrons in an atom determines its chemical properties and therefore what kind of element it is. The arrangement of electrons in an atom's energy levels is responsible for the element's characteristics such as reactivity and bonding behavior.


What is the smallest part of an element which has all the properties of that element?

The smallest part of an element that retains all its properties is an atom. Each atom is made up of protons, neutrons, and electrons that determine the chemical behavior and physical properties of the element.


How can one determine the number of electrons in an element?

To determine the number of electrons in an element, you can look at the element's atomic number on the periodic table. The atomic number represents the number of protons in the nucleus of an atom, which is equal to the number of electrons in a neutral atom.
