what is atomic radius
Answers
Answer:
hii the atomic radiation hi Jennifer yes I will you please give me a copy of my friend
Answer:
The atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding shells of electrons.
Explanation:
Differences
Atomic and ionic radii are distances away from the nucleus or central atom that have different periodic trends. Atomic is the distance away from the nucleus. Atomic radius increases going from top to bottom and decreases going across the periodic table. Ionic radius is the distance away from the central atom.
Analogy
Analogy: Atomic Radius is like a basement. This is because when you add energy levels to the atom it becomes bigger. In a construction, they higher you want to build the building, the deeper the basement has to be.
Characteristics
Summary. Atomic radius is determined as the distance between the nuclei of two identical atoms bonded together. The atomic radius of atoms generally decreases from left to right across a period. The atomic radius of atoms generally increases from top to bottom within a group.
Effective nuclear charge
Across a period, effective nuclear charge increases as electron shielding remains constant. A higher effective nuclear charge causes greater attractions to the electrons, pulling the electron cloud closer to the nucleus which results in a smaller atomic radius. ... This results in a larger atomic radius.
