How many valance electrons are found in a atom of each what elements Helium?
Helium has two valence electrons
Which of these elements have the least number of neutrons helium carbon gold uranium?
Helium has the least number of neutrons among the elements listed.
What are the main elements found in elements?
Hydrogen and helium
Is the gas around a planetary nebula helium?
The amount of helium compared to other elements differ but a nebula occurs so late in a stars lifetime that heavy elements have been synthesized. A nebula is thus often a complex combination of several elements mostly between helium and iron.
What is the role of hydrogen and helium in the sythesis of elements?
Hydrogen and helium are the most abundant elements in the universe. And stars use them for power. To put it simply, hydrogen is fused into helium, and helium into carbon. All the heavier elements are made from there up through iron. The trans-iron elements are made is a supernova. It could be argued that hydrogen and helium are the basic building blocks of other elements.
How many elements are in He?
Helium is one element and does not chemically react.

How many valence electrons do all the elements in the noble gas family except helium have?
8 apart from Helium which has 2
Does helium and fluorine have a similar reaction?
Helium is inert and does not readily react with other elements, including fluorine. Fluorine is a highly reactive element and will readily react with many other elements, but not with helium due to its stable electron configuration.
How many elements have there name ending in ium in the first twenty elements in the periodic table?
Calcium, Potassium, and Helium
Which of these elements have the least number of neutrons helium carbon gold uranium?
Helium has the least number of neutrons among the elements listed.
Does helium contain hydrogen?
No. Hydrogen and helium are separate elements. Elements do not contain other elements. But an element can give off or take electron from other elements.
Does helium have hydrogen in it?
No. Helium and Hydrogen are two different elements.
