What category of elements is a poor conductor?

What category of elements is a poor conductor?

Nonmetals
Nonmetals are (usually) poor conductors of heat and electricity, and are not malleable or ductile; many of the elemental nonmetals are gases at room temperature, while others are liquids and others are solids. The metalloids are intermediate in their properties.

What class of elements is brittle?

The nonmetals are brittle, not malleable or ductile, poor conductors of both heat and electricity, and tend to gain electrons in chemical reactions. Some nonmetals are liquids. These elements are shown in the following figure. The nonmetals in the periodic table.

Is hydrogen a conductor of heat and electricity?

While hydrogen is typically a gas on Earth, it can be artificially compressed and cooled to become a liquid or a solid. Even in these states, hydrogen remains a non-metal — its atoms hold on to their electrons tightly, so hydrogen conducts heat and electricity poorly.

Is hydrogen a good or bad conductor of electricity?

– Hydrogen is a non-metal, but good conductor of electricity only at very high pressure.

What is dull brittle and a poor conductor?

Element that is usually a gas or brittle solid at room temperature and is a poor conductor of heat and electricity are non metals. A metal is an element that has luster, is a good conductor of heat and electricity, is malleable, and is ductile

Which is element is brittle and not a conductor of electricity?

The answer is (4) S. The Ne is gas at STP. Al is a good conductor of electricity and K is soft not brittle. The element of S satisfy all the properties, solid, brittle, and a poor conductor of electricity.. the main goal of the american revolution was to gain .

Which is a poor conductor of heat and electricity?

Non metals, such as Sulfur, Oxygen, and Nitrogen, are poor conductors of heat and electricity. Three properties that are typical of non-metals? gain electrons, poor conductor of heat, poor conuctor of energy, brittle like solid, nonmetalic color

What are the properties of nonmetals opposite to metals?

Nonmetals have properties opposite those of the metals. The nonmetals are brittle, not malleable or ductile, poor conductors of both heat and electricity, and tend to gain electrons in chemical reactions. Some nonmetals are liquids.
