Have a great day :P
This is because of the increasing number of protons in the nucleus, resulting in a stronger attraction of the electrons with the nucleus.
Answer:
hi!
Explanation:
The Mohs Hardness Scale ranks the order of hardness of minerals and some common objects. For example, your fingernail can scratch the minerals talc and gypsum, with a hardness of 2 or lower. A copper penny can scratch calcite, gypsum, and talc.
One of the most important tests for identifying mineral specimens is the Mohs Hardness Test.
This test compares the resistance of a mineral to being scratched by ten reference minerals known as the Mohs Hardness Scale (see table at left).
The test is useful because most specimens of a given mineral are very close to the same hardness. This makes hardness a reliable diagnostic property for most minerals.
"Hardness" is the resistance of a material to being scratched. The test is conducted by placing a sharp point of one specimen on an unmarked surface of another specimen and attempting to produce a scratch.
Answer:
The nucleus is the most densely compacted part of the atom, it is in the center circled by the electron cloud or shells. It is filled with positively charged protons, and neutrons which have no charge. It is smaller than the electron cloud in size, but in quantity it has more subatomic particles since protons and electrons are equal and the nucleus has nuetrons
