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.


What do the protons do?

The number of protons determine the atomic number of an element. There are the same amount of protons as electrons in a regular element.


Can you determine the element with only knowing the number of protons?

The number of protons is the "atomic number", so you look that up in the periodic table.


What do the protons determinate?

The number of protons determine the atomic number of an element. There are the same amount of protons as electrons in a regular element.


Which particle determines the atomic number of an element?

The atomic number of an element is determined by the number of protons.


What is the identity of an element determine by?

The identity of an element is determined by the number of protons.


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.


Why must you know both how many protons and how many neutrons an element has in order to fully identify it?

The number of protons determine what element it is, the number of neutrons determine what isotope it is.


How many protons does have calcium?

Calcium has 20 Protons. You can determine the amount of Protons in an Element by checking the top number of an element. This is called the Atomic number. Calcium has 20 protons


All atoms of the same element have the same numder of?

Protons. Protons determine the atomic number which in turn determine what the element is, so if the number of protons is changed the element is changed. Isotopes have a different number of neutrons and Ions have a different number of electrons than the original atom.


What role does atonmic number play in the periodic table?

The atomic number is the amount of protons in an element. The number of protons completely determine what element an atom is.


A sub atomic particle which determines the atomic number?

Protons are subatomic particles that determine the atomic number of an element. The number of protons in an atom's nucleus is what defines its atomic number; this uniquely identifies each element on the periodic table.
