how rutherford split the atom?

Ernest Rutherford was the first person to knowingly split the nucleus, in 1918 at Manchester University where he bombarded nitrogen with naturally occurring alpha particles from radioactive material and observed a proton emitted with energy higher than the alpha particle.

Normally, the number of electrons is equal to the number of protons, which makes atoms electrically neutral. The number of protons in an atom is the defining feature of an atom. It's what makes one element different from another. The number of protons in an atom is called its atomic number.

The nucleus of an atom consists of neutrons and protons, which in turn are the manifestation of more elementary particles, called quarks, that are held in association by the nuclear strong force in certain stable combinations of hadrons, called baryons.

The nucleus of an atom is comprised of protons and neutrons; it is therefore positively charged.

The number of protons within the atom's nucleus is called atomic number and is equal to the number of electrons in the neutral (non-ionized) atom. Each atomic number identifies a specific element, but not the isotope; an atom of a given element may have a wide range in its number of neutrons.

Protons and neutrons are found in the nucleus of an atom. They make up a majority of the mass of an atom. In fact, the mass number of an element is the sum of its protons and neutrons. Since protons have a positive charge and neutrons are neutral, the nucleus of an atom is electrically positive.

['The number of protons in the nucleus of the atom is equal to the atomic number (Z).', 'The number of electrons in a neutral atom is equal to the number of protons.', 'The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.']

The splitting of a uranium atom releases energy. This process is called “nuclear fission”, since the centre of an atom is called its nucleus. ... When trillions of atoms are split almost simultaneously, the energy released is the power of the atomic bomb.

Answer 1: Ernest Rutherford bombarded nitrogen atoms with helium nuclei (alpha particles), and hydrogen atoms (protons) were formed as a result. From this, he concluded that nitrogen nuclei contained protons. ... Or said more specifically, hydrogen nuclei were always emitted in the process.

TL;DR: A bromine atom has 35 protons, 45 neutrons, and 35 electrons.

They found that atoms are made of even smaller particles. ... The protons and neutrons of an atom are grouped together in the atom's center. This combination of protons and neutrons is called the of the atom. Because it contains protons, the nucleus has a positive charge.

In the first step, a uranium-235 atom absorbs a neutron, and splits into two new atoms (fission fragments), releasing three new neutrons and a large amount of binding energy. In the second step, one of those neutrons is absorbed by an atom of uranium-238, and does not continue the reaction.

Most atoms have three different subatomic particles inside them: protons, neutrons, and electrons. The protons and neutrons are packed together into the center of the atom (which is called the nucleus) and the electrons, which are very much smaller, whizz around the outside. ... Most of an atom is empty space.

Answer and Explanation: The two particles in the atom that are equal in number are the protons and electrons. The protons are located in the nucleus along with neutrons.

Nuclear fission can be caused by hitting a heavy atom with a neutron, or a high energy particle. ... Nuclear fission is the splitting of a heavier radioactive isotope into fragments of intermediate masses. Radioactive decay is the disintegration or decay of the nucleus of a radioactive isotope giving off radiation.

In accordance with the Standard Model of particle physics, protons and neutrons make up the nucleus of the atom, while electrons orbit it in a "cloud". The electrons in an atom are attracted to the protons in the nucleus by the electromagnetic force.

Bohr thought that electrons orbited the nucleus in quantised orbits. ... In Rutherford's model most of the atom's mass is concentrated into the centre (what we now call the nucleus) and electrons surround the positive mass in something like a cloud. Bohr's most significant contribution was the quantisation of the model.
