If you look at the Periodic Table, the atomic number denotes the number of protons in the element. For example, the first element on the table is hydrogen, and it has one proton (the fewest). Element number two is helium, and it has two protons, etc.

Which element has the fewest proton between argon and nitrogen?

The element which has the smallest atomic number has the smallest number of protons. In this case, argon has a proton number of 18 (therefore it has 18 protons in each atom), but nitrogen has fewer protons - it has a proton number of just 7, meaning that it has seven protons per nitrogen atom.


Which isotopic notation identifies a metalloid that is matched with the corresponding number of protons in each of its atoms?

28^Si and 14 protonsThe metalloid Si (silicon) is correctly matched with 14 protons, because the atomic number of Si is 14.

What synthetic element has the fewest protons?

In chemistry, a synthetic element is a chemical element that does not occur naturally on Earth, and can only be created artificially. So far 20 synthetic elements have been synthesized (those with atomic numbers 99-118). so the answer is the element Ensteinium with atomic number 99.


How many protons are in an atom of a pure element?

Each chemical element has a specific number of protons; the number of protons is equal to atomic number of the element.


What has the Atomic nucleus at fewest protons?

What is an element is determined by the number of?

The identity of an element is determined by the number of protons in the nuclei of its atoms. This is the atomic number of an element.


Which element has atoms which contain 5 protons?

The number of protons in an atom of an element?

The number of protons in an atom of an element is its atomic number. It determines the element's identity and is unique for each element. The number of protons also defines the element's chemical properties.


What is the number of protons for an element is the same as the number of the subatomic number?

By definition, the number of protons in the atoms of an element is the atomic number of the element.


How do you determine how many protons are in an element?

The number of protons in an element is determined by its atomic number, which is the whole number found on the periodic table for each element. Each element has a unique number of protons that gives it its specific identity.


What number is the number protons an element has?

There are many different types of elements, all varying in the number of protons they contain. To determine the number of protons in a specific element, refer to the periodic table of elements. The atomic number (generally listed above the element's symbol, sometimes represented as 'Z') is equal to the number of protons in that atom.
