What else can I help you with?
Are the elements in period 1 reactive?
Yes, the elements in period 1, hydrogen and helium, are reactive, but their reactivity is limited compared to elements in other periods. Hydrogen can react with halogens and form hydrogen bonds, while helium is largely inert due to its stable electron configuration.
Which of the following elements is the most chemically reactive helium hydrogen argon or neon?
Hydrogen is the most chemically reactive among the elements listed. It readily reacts with other elements to form compounds, while helium, argon, and neon are inert gases and generally do not undergo chemical reactions under normal conditions.
What makes up two sun?
Hydrogen is the most common element in the universe as a whole; about 75% of the universe by mass is hydrogen (since hydrogen is also the lightest element, that means that the percentage by number of atoms is even higher) . Helium is second; oxygen is a fairly distant third.
How to Use valence electron configuration to explain why helium is safer than hydrogen for use in airships?
Helium has a stable electron configuration with a full outer shell, making it non-reactive and safe to use in airships. In contrast, hydrogen has a single electron in its outer shell, making it highly reactive and prone to combustion in the presence of oxygen, posing a safety risk in airships.
What is the most common element found in star?
Stars contain hydrogen, helium and a little iron.

Which is the most common element between hydrogen and helium?
Hydrogen is the most abundant element in the universe by a wide margin.
Which element is most reactive lithium carbon fluorine or helium?
The most reactive is fluorine.
The two elements most abundant in the universe are?
Hydrogen and helium are the two most abundant elements in the universe.

Stars contain hydrogen, helium and a little iron.
What elements makes up most of the suns mass?
The main two are hydrogen and helium.
What is the most reactive chlorine bromine fluorine and helium?
Fluorine is the most reactive element among chlorine, bromine, fluorine, and helium. It has the highest electronegativity and readily forms compounds with other elements. Helium, on the other hand, is the least reactive noble gas due to its stable electron configuration.
What two elements are commonly found in stars?
The two most common ones are hydrogen and helium gas
