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

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.
Each chemical element has a specific number of protons; the number of protons is equal to atomic number of the element.
helium with 2 proton Hydrogen has 1 proton.
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.
The answer is Boron :)
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.
By definition, the number of protons in the atoms of an element is the atomic number of the 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.
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.
