# What is the relationship between metallic character and atomic radius?

## What is the relationship between metallic character and atomic radius?

Metallic character increases as you move down an element group in the periodic table. This is because electrons become easier to lose as the atomic radius increases, where there is less attraction between the nucleus and the valence electrons because of the increased distance between them.

Atomic radius: The distance between the nucleus of an atom and the outermost shell containing electrons of that atom is known as the atomic radius of that atom. Metallic radius: The one half distance between two adjacent ions of the metal in a metallic lattice is known as metallic radius.

### How does metallic and non-metallic character vary along a period and down the group give reason?

Metallic character refers to the level of reactivity of a metal. Non-metallic character relates to the tendency to accept electrons during chemical reactions. Metallic tendency increases going down a group. Non-metallic tendency increases going from left to right across the periodic table.

How does the ionic radius of a nonmetal compare with its atomic radius?

Explanation: When a non metal gains electrons to become a negative ion the radius increases. The number of protons remains the same so the pull on the electrons is the same. The ionic radius of a nonmetal is greater than its atomic radius.

#### What are the metallic properties and explanation?

Metals are lustrous, malleable, ductile, good conductors of heat and electricity. Other properties include: State: Metals are solids at room temperature with the exception of mercury, which is liquid at room temperature (Gallium is liquid on hot days).

How does metallic character vary in the periodic table?

Metallic character decreases as you move across a period in the periodic table from left to right. This occurs as atoms more readily accept electrons to fill a valence shell than lose them to remove the unfilled shell. Metallic character increases as you move down an element group in the periodic table.

Radius of the circle we use for the singular term and radii word is used to indicate plural.

What is difference between atomic size and atomic radius?

What is Atomic Size? Atomic size is the distance between the centre of the nucleus of an atom and its outermost shell. In basic chemistry, the atomic radius is defined as the shortest distance between the atom’s nuclei and the outermost shell of the atom.

### How does atomic radius vary in a period and in a group?

In general, the atomic radius decreases as we move from left to right in a period with an increase in the nuclear charge of the element. The atomic radius increases when we go down a group because of the addition of an extra shell.

How does the metallic character vary in group and period?

#### How does the ionic radius of a nonmetal compare with its atomic radius quizlet?

How does the ionic radius of a nonmetal compare with its atomic radius? The ionic radius of a nonmetal is larger than its neutral atom. Nonmetals tend to gain electrons in the atom’s current energy level; these additional electrons repel each other and increase the size of the ion.

What is the difference between atomic and ionic radius?

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. Ionic radius increases going from top to bottom and decreases across the periodic table.
