No, a paperclip is not hard enough to scratch calcite. Calcite is a mineral with a hardness of 3 on the Mohs scale, while a paperclip is softer and would not be able to scratch calcite.
Granite is a hard and durable natural stone, so it is unlikely to be scratched by a fingernail. Fingernails are generally not hard enough to scratch granite surfaces.
No, pearls are not hard enough to scratch glass. Glass has a hardness of around 5-6 on the Mohs scale, while pearls have a hardness of 2.5-4, making them softer than glass. So, it is unlikely that a pearl would be able to scratch glass.
The mineral that has a similar hardness to a fingernail is gypsum. Gypsum has a Mohs hardness of 2, which makes it soft enough to be scratched by a fingernail.
The mineral graphite is soft enough to leave a mark on paper. We use graphite, which is a form of carbon, as pencil lead. And it works pretty darn well at leaving marks on paper.

Quartz is hard enough to scratch calcite, as it has a higher hardness rating on the Mohs scale. However, quartz is not hard enough to scratch amphibole minerals, which are generally harder than calcite.
No, a paperclip is not hard enough to scratch calcite. Calcite is a mineral with a hardness of 3 on the Mohs scale, while a paperclip is softer and would not be able to scratch calcite.
No, appetite (also known as apatite) is not hard enough to scratch calcite. Calcite is a mineral that is harder than appetite on the Mohs scale of mineral hardness.
Between 2 and 3 because its hard enough gypsum but it can not scratch calcite because calcite is harder
No, amphibole minerals typically have a hardness of around 5 to 6 on the Mohs scale, while glass has a hardness of about 5.5. This means that amphibole is not hard enough to scratch glass.
dimonds is hard enough to scratch anything.
Diamonds can pretty much scratch any rocks and minerals.On something called, "Moh's Hardness Scale", the Diamond is the hardest one. So some examples of minerals it can scratch,~Corundum~Topaz~Quartz~Orthoclase~Apatite~Fluorite~Calcite~Gypsum~Talcand many, many more.Diamonds are one of the most hardest minerals.Hope I helped! (I'm learning this in science right now!)
The most commonly known mineral that can be scratched with a fingernail is talc.
yes you can scratch paint off of anything with enough time
it is to a point if it is to sharp of an object it will scratch it and if enough pressure is applied
The mineral you are describing is likely quartz, particularly in its clear or colorless form, known as rock crystal. Quartz exhibits a hexagonal crystal structure and is relatively hard, scoring a 7 on the Mohs scale, which allows it to scratch a steel file. Its various colors can arise from impurities or inclusions, leading to varieties such as amethyst or citrine.
