Which elements have similar chemical properties in sulphur and helium?
Sulphur and helium have entirely different properties. Sulphur has properties similar to group 16 elements. Helium has properties similar to group 18 elements.
Why does beryllium and helium have the same valence electrons but not the same chemical properties?
Helium (He) and Be2+ ion (not beryllium element) have the same number of valence electrons (two). But their properties are different as they differ in the number of protons (2 for helium, 4 for beryllium) and hence they differ in ther properties.
Is it accurate to say thet helium has no properties?
Well it is partly true. Helium has physical properties like density, boiling point, conductivity etc. But it has no chemical property.
What are some examples of chemical properties in helium?
Helium is chemically inert; it does not combine with any other element.
Is helium a physical property or chemical property?
Helium is an element that has physical properties. So far it has eluded efforts to make it react with anything else. It could thus be argued it does not have chemical properties other than it is very inert.
What are the chemical properties for helium?
helium is chemically inert and has no chemical properties
What are the chemical properties of helium?
Helium is inert. There are no known compounds. It has no chemical properties.
Which elements have similar chemical properties in sulphur and helium?
Sulphur and helium have entirely different properties. Sulphur has properties similar to group 16 elements. Helium has properties similar to group 18 elements.
What are the properites of helium?
Helium consists of many properties. These properties include low solubility, low boiling point, inertness, high thermal conductivity, and low density. Because of the uniqueness of these elements, helium is often used to control these properties.
Does helium have any alloys?
No, helium is a noble gas and does not have any alloys or metallic properties.
What is the chmical properties of helium?
Helium is chemically inert; it does not combine with any other element.
What do helium and argon have in common?
they have the same properties.
Does helium have properties of both metal and nonmetals?
It is supposed to have properties that of non metals only, but since it has completely filled orbitals, helium is chemically inert
What are the common properties of silver and helium?
Silver is a transition metal. Helium is a non metal and a noble gas. They dont have any similar or common properties.
What are the physical properties of helium?
Helium is a colourless, odourless gas with an extremely low boiling point
Why does beryllium and helium have the same valence electrons but not the same chemical properties?
Helium (He) and Be2+ ion (not beryllium element) have the same number of valence electrons (two). But their properties are different as they differ in the number of protons (2 for helium, 4 for beryllium) and hence they differ in ther properties.
