What else can I help you with?
A family of unreactive element whose atoms do not gain lose or share valence electrons?
Noble Gasses.
The most characteristic property of the noble gases is that they?
The most characteristic property of noble gases is their inertness or lack of reactivity due to having a full outer electron shell. This makes them stable and unreactive under normal conditions.
What element is an unreactive gas that sinks in the air?
The element that is an unreactive gas and sinks in the air is radon. Radon is a noble gas, which means it has a full valence shell and is largely inert, making it unreactive with other elements. Being heavier than air, it tends to accumulate in low-lying areas. Radon is also radioactive and can pose health risks when inhaled in significant quantities.
How chemically active are neon?
Neon is chemically inert, meaning it is very unreactive. Its outer electron shell is full, so it is stable and does not readily form chemical bonds with other elements. This property makes neon useful for applications where a non-reactive atmosphere is needed, such as in neon signs.
What do hurricanes carry with them?
Air consists of a mixture of gasses, including oxygen and carbon dioxide. Wind is the movement of air. Therefore, when there is wind, these gasses move.
What group of elements on the periodic chart are unreactive?
group 8, the noble gasses.
Why is noble gasses the least reactive?
they are unreactive as they have a full outer shell of electrons
The two general types of air pollution are?
Particles and Gasses
Are noble gasses inert gasses?
Noble gases have a full valence shell. Reactions often take place in order for an atom to gain a full valence shell and then become chemically unreactive. Since the noble gases already have a full valence shell, they are unreactive (although some exceptions do aply)
A family of unreactive element whose atoms do not gain lose or share valence electrons?
Noble Gasses.
Why is neon represented on the modern periodic table of the elements?
Neon is an element. It is one of the seven very unreactive noble gasses.
Why are noble gasses are so unreactive?
Noble gases have completely filled outer electronic configuration. Hence they are non-reactive.
What two gasses are used in spacecraft to provide breathing air for astronauts?
oxygen and nitrogen
Which gases are not part of the life processes of many organisms?
Noble gasses, they have no function inside the human body, and are quite unreactive in general.
What is a mixture of gasses?
air
What are two the most common gasses found in air and what are their percentages?
Gases in air are nitrogen about 79%, oxygen about 20% and other gases 1%
Air is a form of what?
air is formed of gasses and matters
