Is the nucleus hard?
The nucleus of atoms is dense and hard. If it was possible to have half a teaspoon of nuclei only it would have a mass of around 400 million tons. The nucleus of an atom is hard and incredibly dense. The nucleus of a cell is made of living material so is not particularly hard. Liquid flows between the nucleus and the cell.

What is one kind of atom turn into another and release energy?
An atom turning into another type of atom and releasing energy can be nuclear fission, where an atom decays into an atom plus atomic particles such as neutrons or alpha particles or even daughter atoms plus particles. It can also be nuclear fusion where two or more smaller atoms link into a larger atom. An example of fusion is four hydrogen nuclei combining to form a helium atom. This is the source of the sun's energy. The mass of the four hydrogen nuclei is a little more than the helium atom mass. The difference is released as energy. The hydrogen bomb tests caused this to happen on earth. We would like to learn to do fusion on a controlled basis as an energy source. So far, in spite of much hard work, no joy. An example of fission is the nuclear reactor which uses one of the Uranium isotopes in rods inserted in a reactor body to cause sustained fission. The Uranium atoms absorb a neutron which causes them to emit several neutrons and split into daughter atoms. Energy is released, the mass of the daughters plus neutrons being less than the mass of the Uranium atom plus neutron.
Is it possible to split the nucleus of a light atom?
It is possible to photoactivate any nucleus except 1H. Be really hard to do, but possible. Light (a Photon) is a "massless" sub-atomic particle (Boson) that has no atomic structure / any structure is sub-atomic; IE: No "Atom, proton, neutron, electron" etc. Because of this it is not an "Atom" and cannot be split. Photon's can be 'cloned' which some term as splitting, however they are not really split as there is nothing to split. Photon's interact with charged electrons and clone themselves into lower frequencies, putting white light through a prism results in bands of colored light (lower frequencies).
What is the the smallest unit?
The word Atom was used many years ago to describe the smallest size anything could be. There have been several changes since then. The smallest unit these days is described as something so small that no-one can see it no mater how hard they look. In scientific notation it is written as 0.000 000 000 000 0001 or a picolitre
Who described an atom as an indestructible sphere?
atom was described as tiny, hard, indestructible sphere by Newton.
The scientist who thought the atom was hard solid ball was?
The scientist who first proposed the idea of the atom as a hard solid ball was John Dalton in the early 19th century. Dalton's atomic theory described atoms as tiny, indivisible particles that made up all matter.
Which item best represents Dalton mental image of an atom?
Dalton's mental image of an atom can be best represented by a solid, indivisible sphere with no internal structure, similar to a billiard ball. This model suggested that atoms were the smallest, fundamental particles of matter.
Did Democritus describe that Atoms are small hard particles?
Yes, Democritus described that atoms are small, indivisible, and indestructible particles that make up all matter. He believed that atoms are constantly moving and combining to form different substances.
Is a atom small and hard?
The original Greeks thought of an atom was that it was a small hard chunk of the matter that it represented, not necessarily ball shaped. As atomic theory developed the models built to represent compounds often used sticks (or springs) and balls to represent the atoms and their bonds. These days an atom is thought to be mostly not there at all. A very small nucleus occupies the center made up of quarks which are hard to describe in physical terms, with an electron density cloud around it showing where the electron might be at any given time. So yes, the atoms are small. And no, they are not hard, at least not hard like a marble.
Why do scientist work hard dedication?
its because the scientist is a scientist so he need to work hard to invent something not only for the world but also for himself.
How did people learn that the earth was a sphere in the late 20th Century?
It's hard to argue it's not a sphere when you've got pictures taken from space showing that it IS a sphere.
A scientist works hard and is persistent?
nonsense
Why is atom energy called atomic energy?
because it is from an atom. think about it atom-ic. not that hard of a concept
Which word most closely means irreducible?
atom APEX Is Hard
Why do scientist work hard with dedication?
they hve to succeed!
Who was the scientist who devoloped the laser?
Charles Hard Towns
