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).
Why do you have static electricity?
you have static electricity because it keeps electrons from moving and here is an example........ lets say you hit a candle and you thought that you hit it hard but it didn't fall over because the static electcity didn't let it fall
The scientist who thought the atom was hard solid ball was?
The scientist was John Dalton
Who described an atom as an indestructible sphere?
atom was described as tiny, hard, indestructible sphere by Newton.
Did Democritus describe that Atoms are small hard particles?
No, Democritus was the first to think of atoms, Dalton thought the atom was an indestructible sphere.
Which item best represents Dalton mental image of an atom?
Dalton's mental image of an atom was a hard sphere that was the same throughout.
Who was the first scientist to give evidence to support democritus idea about atoms?
Democritus did not do any experiments or provide solid evidence for his theory on the atom. In the 5th century B.C, Democritus proposed an atomic model in which all matter is made up of small indestructible units called atoms.
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.
What most accurately represents John Dalton's model of the atom?
John Dalton's model of the atom is accurately represented by solid spheres. These look like tiny snooker balls. He noticed that elements are combined in definite whole number ratios.
Why is atom energy called atomic energy?
because it is from an atom. think about it atom-ic. not that hard of a concept
What is the hard core of an atom?
Nucleus
A scientist works hard and is persistent?
nonsense
