What are Noble Gases? Example and noble gases name Noble Gases Noble gases, sometimes known as inert gases or erosions, are part of the modern periodic table's 18th group. This group is made up of the following individuals: Helium is a kind of gas (He) Neon (Ne) Argon is a gas (Ar) Krypton  (Kr) Xenon is a kind of xenon gas (Xe) Radon is a gas that can cause cancer (Rn) Noble gases exist in a gaseous state under typical temperature and pressure conditions. Because all noble gases have stable electronic structures, they have very little chemical reactivity. They are monoatomic gases that do not readily form molecules. 'ns2np6' represents the basic electrical configuration of noble gases. As a result, noble gases' outermost valence shells can be deemed 'complete.' The chemical inertness of the group of 18 elements is due to this. Because of the stability of certain elements, these gases form a group. These stable elements' crusts are totally filled. Regardles

What are Personal Health and Community Health? Class 9 Science Personal Health  Personal health, which is primarily curvilinear in nature, necessitates individual attention. It is sporadic and episodic. The patient is frequently the centre of attention, and a multidisciplinary approach is used to treat him or her. Personal maintenance is frequently exclusive, necessitating patient consent. Similarly, when performing maintenance, doctors exhibit a higher level of priority and respect. Eating nutritious foods, drinking clean water, preserving personal and local hygiene, approving good lives and a healthy lifestyle, engaging in frequent and serene physical activity, and so on are all ways to maintain one's fitness. Community Health On the other hand, community care is mostly concerned with domestic difficulties and collection. It's continual and beneficial. The primary requirements are defensive care and the requirement for public participation. Although it is sensible and has lon

How are clouds formed? Class 9 Science Clouds are the white floating balls in the sky that resemble cotton. They are not, however, composed of cotton. Tiny water droplets or ice crystals float in the air, forming clouds. The evaporation process of the Sun causes the air to become moist or humid. The wet air above the Earth's surface is evaporated by the Sun. As the altitude goes higher, the water vapour in the air condenses, and droplets form. The droplets cease travelling when they reach a point in the atmosphere known as the dew point. Snowdrops in the sky clump together to form huge droplets, which are made up of water molecules and are referred to be clouds. The tendency for millions of droplets to join clusters causes them to grow in size. The number of droplets in a cloud is determined by the temperature and pressure of the surrounding environment. These clouds become denser and more saturated as they approach the Earth, resulting in rain. That's how we get snow or hail,
