Which of these elements have the least number of neutrons helium carbon gold uranium?
The answer is helium.
What more does a carbon atom have than a helium atom?
Helium has 2 protons, 2 electrons. Carbon has 6 protons, 6 electrons.
Do Aluminum has the greatest number of valence electrons?
Far from it. Aluminum has 3 valence electrons. The highest number is 8, which the noble gases other than helium have (helium has only 2). Metals can have 1, 2, or 3 valence electrons, so aluminum has the greatest number that an element can have if it is a metal. Once you get to 4 valence electrons (which the element carbon has) you are in the nonmetal range.
Why is helium different than carbon with energy?
In quite a lot of ways. --> Helium has two electrons whilst hydrogen has one --> Helium is a noble gas --> Helium is a bigger atom --> Helium's symbol (He) has an "e" compared to hydrogen's symbol (H) --> Helium is less reactive --> Helium doesn't create H-bonds
Which gas has the greatest solubility in water?
Answer:-Carbon dioxide) 863* lil.lUCkiE

What is the difference between a carbon atom and a uranium atom?
I won't even waste the time looking up actual numbers.a mole of atoms of helium is about 4 grams, therefor 1 gram of helium is about 0.25 moles of helium atomsa mole of atoms of uranium is about 238 grams, therefor 1 gram of uranium is about 0.0042 moles of uranium atomsA gram of helium contains more atoms than a gram of uranium by about a factor of 60.
Who has the greatest atomic radius out of Helium Oxygen Carbon Nitrogen and Potassium?
na
What element has the same amount of neutrons and electrons?
There are several such elements. Examples are helium and carbon.
What elements are likely be formed by the sun at some time in its life a helium and carbon b iron and uranium c hydrogen and iron d carbon and lead?
A. Helium and carbon. The other heavier elements such as iron, uranium and lead will be created only in the explosions of supernova stars, such as the one discovered just last week (late May, 2011).
How many electrons are needed in hydrogen helium carbon and oxygen to fill their respective valence shells?
Hydrogen has one electron and needs one more. Helium has two electrons and has filled shell. Carbon needs four more electrons to fill the valence shell Oxygen needs two more electrons to fill the valence shell
