In general terms, how does each of the following atomic properties influence the metallic character of the main-group elements i
vekshin1

Metallic property also rises with increasing atomic radius. Metallic character reduces with an increase in the amount of outer electrons.

<h3>What is atomic radius?</h3>

A chemical element's atomic radius, which is typically the average or typical distance between the nucleus's core and the outermost isolated electron, serves as a gauge for the size of an atom. There are numerous non-equivalent definitions of atomic radius since the border is not a clearly defined physical entity. Van der Waals radius, ionic radius, metallic radius, and covalent radius are the four most frequently used definitions of atomic radius. The atomic radius is often measured in a chemically linked condition because it is difficult to isolate individual atoms to measure their radii separately. However, theoretical computations are easier when considering isolated atoms.

A laser pointer emits light that has a wavelength of 5.32x 10–7 m. What is the frequency of the light?
butalik [34]

Answer:

Frequency = 0.6 × 10¹⁵ s⁻¹

Explanation:

Given data:

Wavelength = 5.32 × 10⁻⁷ m

Frequency = ?

Solution:

Formula:

speed of light = wavelength × frequency

Frequency = speed of light / wavelength

Frequency =  3 × 10⁸ m/s /  5.32 × 10⁻⁷ m

Frequency = 0.6 × 10¹⁵ s⁻¹
