then every element would have more or less the same chemical properties as hydrogen and helium. Instead, as you move along the periodic table, every new electron tries to settle
Hydrogen, helium, carbon Iron, nickel, oxygen, silicon Comparable meteorites None. Only about 0.1 % of the sun has the composition of carbonaceous chondrites. About 99% of the sun has the same composition as ordinary meteorites. Comparable planets ...
Other than moisture, what are the three major components of the air you breathe? - 78% oxygen, 21% hydrogen, 0.9% nitrogen - 78% oxygen, 21% nitrogen, and 0.9% helium - 78% nitrogen, 21% oxygen, and 0.9% argon - 78% nitrogen, 21% hydrogen, and 0.9% oxy ...
1. Why is the ionization energy of helium greater than that of the other elements? Why does gravity not present in space? What makes radioactive atoms get old so quickly and decay? Explain why hydrogen and helium atoms have the necessary speed to escape but why other elements, such as oxy...
Choose the element from the list below. a. sodium chloride b. rust c. hydrogen peroxide d. water e. helium You are given a mixture of iodine solid and sodium chloride ( Hint: iodine is not soluble in water), what method(s) can you use ...
KjPn 6 was tentatively classified as a typePN, though its helium abundance is smaller than the minimum prescribed value and the sum of its nitrogen and oxygen abundances is low. The object is about 800above the galactic plane, is bipolar and shows no trace of molecular hydrogen. The ...
