Find the names of 20 metals having Atomic Mass less than 50 their symbol, physical state
What else can I help you with?
What is the atomic mass of magnets?
Magnets can be made from many different metals so there is no specific atomic mass.
What element in the periodic table has atomic mass of 230 with 86 electrons?
Rn has 86 electrons, Th is the closest to having an atomic mass of 230
How do you figure the mass of an atom?
You add up the mass of the protons, neutrons, and electrons. Protons and Neutrons having an atomic mass of 1, and electrons having an atomic mass of roughly 1/1800.
What do you get if you plus the atomic number and the atomic mass?
a number having no physical meaning.
What element hase an atomic mas of 106.42?
Element Palladium has an atomic mass of 106.42 .It has atomic number 46.It belongs to the group of transition metals.
What is the largest element in the alkali metal?
No. In fact lithium, one of the alkali metals, is the lightest metal. In terms of molecular mass the heaviest metals are the actinides. In terms of density the densest metals are osmium and iridium.
What alkali-earth metals have an atomic mass greater than strontium?
Barium (Ba), Radium (Ra) have atomic masses greater than strontium.
Why do elements have a listed average atomic mass and not just atomic mass?
Because most naturally occurring elements are a mixture of isotopes, each having a different atomic mass. These individual isotopic atomic masses must be combined accounting for the amount of each isotope of the element is present to get a weighted average atomic mass.
Why is a sodium cation not likely to be a heavy metal?
A sodium cation is not likely to be considered a heavy metal because it is a light element with a low atomic number and relatively low atomic mass. Heavy metals are typically defined as metals with high atomic numbers and densities, which sodium does not exhibit.
Why do alkali metals have a low density?
Alkali metals have a low density because they have a single valence electron that is loosely held, leading to larger atomic size and lower atomic mass. This results in a less compact arrangement of atoms, contributing to the low density observed in alkali metals.
Explain Why is atomic mass unit used to express atomic mass?
Originally these relative masses were based on hydrogen, known to be the lightest element, having a mass of 1 u, and all the MORE
Why does the density of group 2 metals increase?
The density of group 2 metals increases as you go up the group. This is because atomic radius decreases as you go up the group. Density is mass / volume and the ratio of mass to volume of atoms of the elements goes up with the decrease in radius.
