What gas element has an atomic mass less than 30 is not neon and is a noble gas?
helium (He)
What is one less proton than noble gas?
A noble gas is an element found in group 18 of the periodic table, characterized by having a full outer electron shell. Therefore, one less proton than a noble gas would place the element in group 17 of the periodic table, known as the halogens. Halogens have one less proton than noble gases and are highly reactive nonmetals.
What elements mass is 30 and a noble gas but not neon?
The element with a mass of 30 and is a noble gas, other than neon, is krypton (Kr). With an atomic number of 36, krypton has 36 protons in its nucleus and typically has 44 neutrons in its most common isotope, giving it an atomic mass near 84.
What is the element that densest noble gas?
The element with the densest noble gas is radon (Rn). It is a radioactive noble gas that is heavier than the other noble gases, making it the densest.
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.
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 is a noble gas with a mass of less than 15?
Helium
What gas element has an atomic mass less than 30 is not neon and is a noble gas?
helium (He)
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 is one less proton than noble gas?
A noble gas is an element found in group 18 of the periodic table, characterized by having a full outer electron shell. Therefore, one less proton than a noble gas would place the element in group 17 of the periodic table, known as the halogens. Halogens have one less proton than noble gases and are highly reactive nonmetals.
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 elements mass is 30 and a noble gas but not neon?
The element with a mass of 30 and is a noble gas, other than neon, is krypton (Kr). With an atomic number of 36, krypton has 36 protons in its nucleus and typically has 44 neutrons in its most common isotope, giving it an atomic mass near 84.
What is the element that densest noble gas?
The element with the densest noble gas is radon (Rn). It is a radioactive noble gas that is heavier than the other noble gases, making it the densest.
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
Elements in my family usually form covalent bonds. We have two fewer valence electrons than the noble gases. I am almost twice as heavy than the lightest element in my group. What element am i?
Sulfur: The periodic column containing elements with two fewer electrons than the noble gases is column 16, in which oxygen, the lightest element, has a mass number of 16. Sulfur, the next element in this column, has a mass number of 32.
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 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.
