Excerpt from ERG Guide 121 [Gases - Inert]: Do not touch or walk through spilled material. Stop leak if you can do it without risk. Use water spray to reduce vapors or divert vapor cloud drift. Avoid allowing water runoff to contact spilled material. Do not direct water at spill or source of leak. If possible, turn leaking containers so that gas escapes rather than liquid.

All elements are listed alphabetically on the inside front cover. Classify each of the following pure substances as an element or a compound: a. helium gas (He) b. mercury (Hg) in a thermometer c. sugar \left(\mathrm{C}_{12} … Helium (He), chemical element, inert gas of Group 18 (noble gases) of the periodic table. The second lightest element (only hydrogen is lighter), helium is a colourless, odourless, and tasteless gas that becomes liquid at −268.9 °C (−452 °F). The boiling and freezing points of helium are lower than those of any other known substance.

Paki sagot po kung element or compound tas paki explain po thanks Helium is unreactive because it has a closed-shell electron configuration. Since it’s completely full, it’s not happy with sharing or ceding electrons.

Helium is the second most prevalent element in the universe, after hydrogen.However, the atmosphere contains only 5 ppm volume of helium. Helium concentrations in seawater are no higher than 4-7 ppt. Concentrations are relatively low, because helium as a noble gas only occurs as separate atoms, and usually does not react with any other particles. Classify the following into elements and compounds., mercuric oxide, helium gas, water, table salt, iodine, mercury, oxygen, nitrogen. - 12120901 Helium is second only to hydrogen in abundance throughout the universe, and is at the heart of the sun and all stars’ fusion furnaces.

Helium is the second least reactive element and noble gas (after neon). Its low atomic mass, thermal conductivity, specific Helium (He), chemical element, inert gas of Group 18 (noble gases) of the periodic table. The second lightest element (only hydrogen is lighter), helium is a Feb 16, 2017 Helium is a famously inert element, but researchers have made a sodium and helium gas to high pressures of up to 155 gigapascals. Above 113 GPa, the team noticed the formation of a stable crystalline compound, Na2He,& Feb 6, 2017 It is a member of a family of seven elements called the noble gases, “The compound that we discovered is very peculiar: helium atoms do not Hydrogen is an element, usually in the form of a gas, that consists of one proton and one electron.
