You are likely referring to Neon (Ne), which has an Atomic Mass of approximately 20.18 atomic mass units. Neon is a noble gas, known for its lack of chemical reactivity and is commonly used in neon signs and lighting.
The atomic weight of Silicon is 28.086 amu (atomic mass unit) NOTE* An atomic mass unit is approximately 1.66053886 x 10-27 kg.
The atomic mass of strontium is not a whole number because it is an average value that takes into account the abundance of different isotopes of strontium in nature. These isotopes have different masses and occur in different proportions, resulting in a weighted average atomic mass that is not a whole number.
Magnisium has a different atomic mass to sodium plus they are in 2 separate periods, but im not sure about having more protons :)
right..... im not sure about it but since the atomic mass of zinc is 65.39 amu then most probably it will be 65 amu rounded to the nearest whole number. hope that helped :D
The relationship between an element's mass and its atomic number is linear because the mass of an atom is primarily determined by the number of protons and neutrons it contains. As the atomic number increases, so does the number of protons and neutrons in the nucleus, leading to a proportional increase in mass. This linear relationship is a result of the fundamental structure of atoms and the way in which they are composed.

Im not sure about the atomic mass bit but Lanthanum is a silvery white, malleable, ductile, and soft rare-earth metal xx

the answer is 109... im not positive that im right but if i am right heres what you do... subtract the atomic mass from the atomic number(number of protons.) :p
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
you cant get the # of neutrons if there is no atomic mass because you have to subtract the atomic # from the atomic mass #. so there is no way that u can find the # of neutrons without the atomic mass it is needed!

We don't round off atomic masses. The averaged atomic mass depends on the proportions of the various isotopes of that element. In this case, the element is hydrogen, which normally has an atomic mass of 1. Most hydrogen atoms have a single proton and no neutrons, so a total of 1. There's an isotope of hydrogen sometimes called "heavy hydrogen" or "deuterium", which has one proton (which makes it hydrogen) but which also has one neutron, for an atomic mass of 2. You can probably calculate how many "1"s you need to include for each "2" to make the average 1.0079. It's a bunch. There's an even heavier isotope called "tritium", which has one proton and two electrons, for an atomic mass of 3. Tritium is radioactive, and does not occur in nature except as a product of radioactive decay.
An atom of lead has more mass than an atom of gold. This is because lead has a higher atomic number than gold, meaning it has more protons and neutrons in its nucleus, resulting in a greater atomic mass.
im not an expert but im guessing 0.01$
