It is a colorless, odorless, tasteless, nontoxic, and nearly inert gas that heads the noble gas series in the Periodic Table
What else can I help you with?
What are some characteristics of helium?
Helium is an inert gas. It has 2 electons.it is non reactive.
What is the smallest unit of Helium that still maintains all of the same characteristics of Helium?
The smallest unit of helium that retains all its characteristics is a helium atom. A helium atom consists of two protons, two neutrons, and two electrons, which together define its chemical properties and behavior. When helium is in its elemental form, it exists as a monoatomic gas, meaning each atom functions independently while still exhibiting the characteristics of helium, such as being non-reactive and having a low density.
Why hydrogen and helium are out of periodic table?
Hydrogen and helium aren't 'out' of the periodic table, hydrogen just has characteristics that match up with group one (very reactive) and helium has characteristics that match up with group 8 (non reactive).
Is helium gas a pure substance?
Yes, helium gas is considered a pure substance because it is made up of only helium atoms. It is a unique element with its own distinct chemical properties and characteristics.
What characteristics does reggae have to pop?
For Reggae to pop you must fill it with helium and then stick it with a pin
What is the general characteristics of helium?
Helium is a colorless, odorless, and tasteless gas. It is the second lightest element and is non-reactive, meaning it rarely forms chemical compounds. Helium has the lowest boiling and melting points of all the elements.
What happens when you mix hydrogen and helium?
When hydrogen and helium are mixed, they will not react chemically because they are both inert gases. Instead, they will form a gaseous mixture with the properties of both gases, maintaining their individual characteristics.
What chemical bears similar characteristics to neon?
all noble gases such as helium, argon, krypton, xenon, radon
Is helium a semi-metal?
No, helium is not a semi-metal. It is a noble gas that exists as a monatomic gas at room temperature and does not exhibit the properties of semi-metals, which are elements that have characteristics of both metals and nonmetals.
Characteristics of helium?
Helium is a gas which is very light. It is the second lightest element in the universe. Helium was discovered in 1986. William Ramsay confirmed it was helium. Helium remains as gas up to 25c (77f). Helium has no taste or no color. Helium doesn't combine with other elements. It is a by product of the reaction of hydrogen in the sun.
Is helium metal non metal or metalliod?
Helium is classified as a non-metal. It is a noble gas and is characterized by its lack of reactivity and non-metallic properties. Unlike metalloids, which exhibit properties of both metals and non-metals, helium does not possess any metallic characteristics and exists as a gas at room temperature.
How are stars the same as sun?
Our Sun is a star; the stars are suns. Look up "star" in Wikipedia, for example, to find out the characteristics of stars; most of these characteristics apply to our Sun. But basically, stars are huge balls of gas (or plasma, to be more accurate), usually mainly hydrogen and helium, hot and dense enough to ignite nuclear fusion (converting hydrogen into helium, at first).
