A sample of a solid nonmetal is compared to a sample of a solid metal. Both samples have the same volume. What is the

EleoNora [17]

Answer:

STRUCTURE:

Metals have a crystalline structure, whereas non-metals possess amorphic structure.

At room temperature, metals are usually solid, except mercury and gallium which are in the liquid state. Conversely, non-metals can be found in solid or gaseous form, except Bromine which is the only non-metal that is present in liquid form.

Density is the ratio of mass to volume; metals have a higher density as compared to non-metals.

Metals look smooth and shiny, while non-metals usually appear dull.

When it comes to hardness, metals are generally hard substance, but it varies from substance to substance. Unlike non-metals is soft substance except diamond, which is the hardest substance on earth.

CHEMICAL PROPERTIES:

Metals support conduction of heat and electricity. Conversely, non-metals are insulators, and so they do not support conduction of heat and electricity.
Metals have a very high melting and boiling point. In contrast, non-metals are boiled and melted at a relatively low temperature.
In the outer shell, metals consist of 1 to 3 electrons, whereas non-metals consist of 4 to 8 electrons.

Which equation was used by Albert Einstein to explain the photoelectric effect? [E = energy, h = Planck’s constant, and v = freq

devlian [24]

Answer:

E = hV

Explanation:

Hello,

Photo electric effect theory was borne out the the confusing if light was either a particle or a wave. However Albert Einstein came up with a theory that light was a particle and each particle carry a certain amount of energy referred to as photons.

He used Max Planck's idea and theorized that since light is made up of photon, when each photon comes in contact with the surface of a metal, the energy is transferred to the electron.

E = hv

E = energy of the photons

h = Planck's constant = 6.626×10⁻³⁴Js

v = frequency of the photon in Hz
