No halogen gas has a mass of under 15 Atomic Mass units. The closest is fluorine, at 19.0 atomic mass units.
What else can I help you with?
If nothing is as effective as stating the obvious but with less than one ounce of this halogen existing on Earth what is this element?
The element with less than one ounce existing on Earth is astatine. It is a rare halogen element and is primarily produced through artificial means due to its scarcity in nature.
What element is less electronegative than silicon?
Aluminum is less electronegative than silicon.
Which element is less dense silver or gold?
Silver is less dense than gold. Gold has a higher density compared to silver, which means that a unit volume of gold will have more mass than the same volume of silver.
Which is usually the larger number the mass number of an element or the formula mass of a compound that contains the element?
The formula mass of a compound that contains the element would be a larger number than the mass number of the individual element. The individual element would simply be the mass of just that one atom, where as the compound would be the mass of that atom plus the other masses of the other atoms that make up the compound. ex. Oxygen-O has a mass number of about 16 grams. Water-H2O has a formula mass of 2 x mass of Hydrogen-H (about 1) + the mass of Oxygen-O 16 = 18 grams. A formula mass of 18 g is more than a mass number of 16 g.
Is a noble gas with 48 neutrons and a mass of less than a 100?
The noble gas with 48 neutrons and a mass of less than 100 is Krypton. It has an atomic number of 36, which means it has 36 protons in its nucleus. The total mass of Krypton is slightly less than 100 atomic mass units.
What element has less than one halogen existing on the earth?
Any element, other than a halogen is - by definition - not a halogen and so it does not have a halogen and that is less than one halogen.
What element is a halogen gas with a mass less than 25?
Fluorine, at 19 atomic mass units, is the only halogen gas that fits that requirement.
If nothing is as effective as stating the obvious but with less than one ounce of this halogen existing on Earth what is this element?
The element with less than one ounce existing on Earth is astatine. It is a rare halogen element and is primarily produced through artificial means due to its scarcity in nature.
What element has an atomic mass greater than 75 but less than 79?
Element 34, Selenium, has an atomic mass of about 78.96.
What element can have the atomic number 118 and also the mass number 50?
No element can have those features; the mass can never be less than the atomic number in any element.
What element has mass less than thirty?
well a lot of elements have atomic mass so then you would have to look at the periodic table to find the right answer
Which is the third most reactive halogen?
Bromine (Br2) is the third most reactive halogen.
Why can an element have the same atomic mass as another element?
Two elements can have the same atomic mass if one has more or less neutrons than protons in the nucleus. These are called isotopes. not much to im prov thank you
What is the element with the least atomic mass is hydrogen or helium?
Hydrogen's atomic mass (1 amu for the most stable isotope) is less than that of helium (4 amu).
What contains a halogen?
A halide is a compound consisting of two parts; a halogen and another electronegative element. The mostcommonhalogens arefluorine(F),chlorine(Cl),bromine(Br),iodine(I), andastatine(At). If put together with another element, they formfluoride,chloride,bromide,iodide, orastatide. Therefore, your question is not right since a halide consist of elements and one element can only be a halogen or non-halogen. (halogen and halide are two different things)
Which halogen has a greater mass then sulfur but lower mass than iron?
Sulfur atomic mass: 32 a.m.e.Chlorine atomic mass: 35.5 a.m.e.Iron atomic mass: 56 a.m.e.
Does a radioactive element become stable after its mass number become less than 82?
Not always -- Hydrogen-3 is radioactive, for example.
