If the pair of materials listed below were rubbed together, give the charge that each would have in the same order as listed. us
const2013 [10]

Answer:

Simply put, the property of electron affinity refers to the relative amount of love that a material has for electrons. If atoms of a material have a high electron affinity, then that material will have a relatively high love for electrons. This property of electron affinity will be of utmost importance as we explore one of the most common methods of charging - triboelectic charging, also known as charging by friction or rubbing.

Suppose that a rubber balloon is rubbed with a sample of animal fur. During the rubbing process, the atoms of the rubber are forced into close proximity with the atoms of the animal fur. The electron clouds of the two types of atoms are pressed together and are brought closer to the nuclei of the other atoms. The protons in the atoms of one material begin to interact with the electrons present on the other material

The appearance or quality of light reflected from the surface of a mineral is known as ________.
bija089 [108]

The appearance or quality of light reflected from the surface of a mineral is known as luster.

In mineralogy, luster refers to how a mineral surface appears in terms of its capacity to reflect light. The degree of transparency, diaphaneity, and structure of a mineral all affect its luster.

A mineral's ability to reflect light is referred to as luster. The first step in identifying a mineral is to measure it. Always examine a brand-new surface for luster; you might need to remove a tiny amount of material to reveal a clean sample. Metallic luster, which is extremely reflective and opaque, to dull luster (non-reflective and opaque.)

Mineralogists use the physical characteristic of luster to identify minerals. A mineral's luster defines how its exterior reflects light and how its inside may bend or refract light. Some minerals have a metallic sheen, while others don't.

A mineral reflects light by having a luster. The two main categories of luster are described by the labels metallic and nonmetallic. The most popular words for luster are shown in Table 7, along with an illustration of a comparable mineral. Some minerals are described as "earthy," "chalky," or "dull" because they lack luster.
