What kind of element is made of only one atom water air helium or sugar?
Elements
How many elements does helium have?
ONE, Helium is an element, not a molecule.
Why helium and magnesium are both elements and not compound?
because they are made up of only one metal
How many different types of atoms are in helium?
Helium is an element, so it is made of only one type of atom.
Why is helium grouped differently?
It is one of the inert gases. These do not react or form compounds with other elements.
What kind of element is made of only one atom water air helium or sugar?
Elements
Which elements have only one electron in itz orbit orshell?
hydrogen (H) and helium (He)
How many elements are in He?
Helium is one element and does not chemically react.
How many elements does helium have?
ONE, Helium is an element, not a molecule.
Why helium and magnesium are both elements and not compound?
because they are made up of only one metal
What is the name for elements are only made up of one atom?
The answer is Helium, made up of one molecule of that element. He1 = 1
How are elements and compounds alike and different?
The only similarity elements and compounds share are that they're the building blocks of matter. Their differences are that elements are are made of only one type of periodic element. Compounds are made of at least two periodic elements bonded together. For example, salt is a compound of sodium-chloride and the helium in balloons is made up entirely of helium molecules.
How many different types of atoms are in helium?
Helium is an element, so it is made of only one type of atom.
Should helium be classified as a mixture?
Helium is one of the elements of the periodic table. Helium in the shape where people can get in contact with it may have traces of other elements in it depending on the level of purity, but it's still mainly just helium and almost nothing else.
What makes these two elements helium and hydrogen different from one another?
They both have only ONE, the smallest, electron orbital occupied: H: 1s1 and He: 1s2
What is one important fact about helium?
Helium is the second lightest element. Helium has the lowest boiling point among all the elements. It is chemically inert.
What is helium in relation to hydrogen?
The atomic number of helium is one more than that of hydrogen. In both the elements, the electrons are filled in the 1s orbitals. Hydrogen has one electron, helium has two.
