Which atom has the most mass?
OganessonOganesson has the highest atomic number and highest atomic mass of all known elements.
The radioactive oganesson atom is very unstable, and since 2005, only five (possibly six) atoms of the isotope oganesson-294 have been detected..
What do you call the element from atomic number 57 71?
Lanthanides. What do you call the element series from atomic number 57-71? Silicon.
Is anything smaller than a quark?
2 Answers. All we know about the size of quarks is that they are smaller than the resolution of any measuring instrument we have been able to use. In other words, they have never been shown to have any size at all.
Which particle has least mass?
electronThe fundamental particle that has least mass is electron.
Which subatomic has least mass?
ElectronElectron is around 1800 times less mass than a proton or neutron. Since a nucleus contains multiple protons and neutrons, it is obviously has less mass than a nucleus also. Thus, the correct answer is (A).

Where is the atomic mass?
At the upper left is the atomic number, or number of protons. In the middle is the letter symbol for the element (e.g., H). Below is the relative atomic mass, as calculated for the isotopes found naturally on Earth. At the very bottom is the name of the element (e.g., hydrogen).
What is the tiniest thing in the world?
quarksProtons and neutrons can be further broken down: they’re both made up of things called “quarks.” As far as we can tell, quarks can’t be broken down into smaller components, making them the smallest things we know of.
Is there anything smaller than a Preon?
What is smaller than a Preon? … Following the discovery of quarks inside protons and neutrons in the early 1970s, some theorists suggested quarks might themselves contain particles known as ‘preons’.
Which has the smallest mass in an atom?
hydrogen atomThe atom with the smallest mass is the hydrogen atom; its mass is about 10-27 kg. The masses of other atoms go up to about 200 times this. The nucleus of an atom is about 10-15 m in size; this means it is about 10-5 (or 1/100,000) of the size of the whole atom.
Which one is the smallest particle?
An atom is the smallest particle of an element, having the same chemical properties as the bulk element. The first accurate theory explaining the nature of matter was Dalton’s Atomic Theory: 1. All matter is composed of atoms, and atoms are indivisible and indestructible.
