What are properties of semimetal?
Semi-metals have some properties of metals and some from nonmetals. Semi-metals are solid at room temperature. They are also brittle, hard, and somewhat reactive.
What are the properties of lead sulfide?
Sulfides such as pyrite (feS2) are compounds of sulfur and one ore more elements.
Are most metal elements brittle and don't conduct electricity?
Most metal elements are not brittle and do conduct electricity. However, there are exceptions, such as bismuth and mercury, which are brittle or poor conductors of electricity. Overall, metals are known for their malleability and good conductivity of electricity.
What elements is hard and dense has a high melting point and boiling point is fairly reactive and has two electrons in its outermost orbit?
This description matches the element calcium (Ca), which is hard and dense, has a high melting and boiling point, is fairly reactive, and has two electrons in its outermost orbit. Calcium typically forms 2+ cations when it reacts with other elements.

It is the Earth's crust.

hard and brittle so YES
Is pencil considered hard or brittle?
hard
What is the opposite of hard that starts with the letters 'br'?
brittle
Difference between hardness and brittleness?
Hardness is the question of how difficult it is to make an impression on a substance. Brittleness is the question of how easy it is to break. Granite is a stone which is very hard but not brittle--it is hard to carve and also hard to break. A plank of wood is not as hard as stone but is not very brittle. You can carve on it with a knife but it won't shatter if you drop it. Glass is hard and brittle. Chalk is not hard but it is brittle.
Do starfish get hard when they die?
They get hard and brittle when they dry out.
What is a sentence for brittle?
To be brittle is to be hard and breakable. An example sentence would be: The older she got, the more brittle her bones seemed to be.
Is carbon brittle as it is hard?
While carbon can be very hard, it is not necessarily brittle. The properties of carbon can vary depending on its structure and form. For example, diamond is a form of carbon that is both extremely hard and strong, while graphite is another form of carbon that is soft and brittle.
What are the properties of lead sulfide?
Sulfides such as pyrite (feS2) are compounds of sulfur and one ore more elements.
Is silicon mallebale?
Silicon is not malleable in its pure form. It is a brittle and hard material. However, when combined with other elements in alloys, such as in steel or aluminum, it can enhance malleability.
