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.

Do electrons determine what kind of element an atom is?
The number of protons determine the element. It is equal to the atomic number. The number of electrons is equal to the number of protons only of the atom is neutral.
What is the smallest unit in an element?
The smallest unit of an element is the atom. There are smaller components of atoms, but they no longer hold the properties of the element that belong to an atom of that element. There are smaller things called quarks but they are not very well understood. Of the neutron, proton and electron, the electron is by far the smallest.
What number of the outer energy level of an atom helps determine which category an element belongs in?
electrons
What is the smallest amount of an element?
The smallest part of an element that has the properties of that element is the atom.
What is the smallest part of an element that is still that element?
The smallest part of an element that still retains its properties is an atom.
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 is the same as the number of protons in the nucleus of an atom of that element and/or the number of electrons a in neutral atom of that element.
Do electrons determine what kind of element an atom is?
The number of protons determine the element. It is equal to the atomic number. The number of electrons is equal to the number of protons only of the atom is neutral.
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.
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.
What is the smallest piece of an element that still retains the properties of the element?
The atom. Anything smaller is an atomic particle from which all elements are made.
What does the number of protons in a nucleaus determine of an atom?
The number of protons in the nucleus of an atom determines the atomic number of the element to which the atom belongs.
If you know the number of electrons in a neutral atom can you determine what the element is?
Yes, in a neutral atom the number of electrons and protons is equal, and it is the number of protons that determines what element the atom is. So, by looking at the number of electrons you can tell what element it is.
How do you determine the number of electrons inone atom of an element?
the number of electrons of an atom is the same as it's atomic number
