Iodine: Nonmetallic chemical element, chemical symbol I, atomic number 53.

The atomic number represents the number of nuclear protons or, in the undisturbed state, the number of extranuclear electrons.

No change in atomic number is possible without a radical change in properties.

PROFESSOR: five — there's five valence electrons, but the atomic number is actually seven.

Potassium: chemical element, one of the alkali metals, chemical symbol k, atomic number 19.

That is why this says atomic number, but for most intents and purposes we can say this could be atomic mass.

a tabular arrangement of the chemical elements according to atomic number as based on the periodic law.

"Radioisotopes" refer to a certain type of elements producing radiation decay that have the same atomic number but different mass of nuclides.

The dependence of relative intensity and frequency of bands of aromatic ring on the atomic number of lanthanides indicates the presence of a double-double effect.

So, let's say we have an atomic number of 3, 3 that means we have 3 electrons, so we better hope to get our neutral atom that we have a charge of plus 3in the nucleus.

" Boron： Semimetallic chemical element, chemical symbol B, atomic number 5. Pure crystalline boron is a black, lustrous, very hard but brittle semiconductor that does not occur naturally. Boron compounds are found widely dispersed as various minerals, including borax and the gemstone tourmaline."

Here is atomic radius versus atomic number.

Each element has a number, size is equal to the number of elements in the nucleus electron atom, this number is called the atomic number.

In order to improve radiation resistivity, the elements with smaller atomic number should be selected as dopants in both core and cladding of the fiber.

They have the same atomic number and hence nearly identical chemical behaviour but different atomic masses.

British physicist who determined that the atomic number of an element can be deduced from the element's x - ray spectrum.

In each period, the atomic number of each element is increasing.

"Sulfur: Nonmetallic chemical element, chemical symbol S, atomic number 16. It is very reactive but occurs native in deposits, as well as combined in various ores (e.g., pyrite, galena, cinnabar); in coal, petroleum, and natural gas; and in the water in sulfur springs."
