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.
If a single atom of an unidentified element has a mass of 3.818x10-23 g What is the element?
The mass number can be found by multiplying the mass of a single atom by Avogadro's number, that is 6.022 X 1023. In this instance, the product is 23.0, and the element is probably sodium, which has this gram atomic mass. mass number is less than 1, which does not correspond to any real, stable atom. The element could conceivably be a rare isotope of neon or magnesium.
What element has a mass of less than 30 and is a noble gas?
Neon's mass is the element closest to 30 out of all noble gasses.
What gas element has an atomic mass less than 30 is not neon and is a noble gas?
helium (He)
The atomic mass of iodine is less than the atomic mass?
The atomic mass of iodine is less than the atomic mass of all elements with greater atomic number.
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 is an element that is a Halogen Gas and with a mass less than 15?
No halogen gas has a mass of under 15 atomic mass units. The closest is fluorine, at 19.0 atomic mass units.
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?
Astatine
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 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)
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
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).
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.
