What is my atomic number?


What is my atomic number?

The atomic number is the number of protons in the nucleus of an atom. The number of protons define the identity of an element (i.e., an element with 6 protons is a carbon atom, no matter how many neutrons may be present).

What is effective atomic number example?

Effective atomic number (EAN), number that represents the total number of electrons surrounding the nucleus of a metal atom in a metal complex. The EAN rule is often referred to as the “18-electron rule” since, if one counts only valence electrons (6 for Co3+ and 2 × 6 = 12 for 6 NH3), the total number is 18.

Is radiolucent dark or light?

Radiolucent – Refers to structures that are less dense and permit the x-ray beam to pass through them. Radiolucent structures appear dark or black in the radiographic image. Radiopaque structures appear light or white in a radiographic image.

What are the 12 elements?

The twelve elements of nature are Earth, Water, Wind, Fire, Thunder, Ice, Force, Time, Flower, Shadow, Light and Moon. Each of these elements are simplified terms for higher and complex substances.

What does mass number tell you?

An element’s or isotope’s mass number tells how many protons and neutrons in its atoms.

How do you read mass number?

The mass number is the sum of the number of protons and neutrons in an atom. The mass number can be calculated by adding the atomic number and the number of neutrons. The mass number can be written as a superscript to the left of the symbol for the element.
