Define atomic number?
Number of protons located in the nucleus.
What is an atom and what does it consist of?
An atom is the smallest amount of an element that still retains that element's properties. An atom is made up of protons, neutrons, and electrons. Protons have a positive charge, and are part of the nucleus. Neutrons have no charge, and are part of the nucleus as well. Electrons have a negative charge, and orbit the nucleus. Scientists also believe that protons and neutrons are made up of quarks.
An atom consists of a?
protons(+) an neutrons(=) inside the nucleus and electrons(-) revolving around it.
What is a plutonium?
A radioactive element with several isotopes that always has 94 protons within its nucleus.
The parts of an atom?
Well there is protons, electrons, and neutrons. Protons and neutrons are in the nucleus and the electron i outside revolving around it. The number of them depends on what periodic element specifically.
The nucleus of an atom is charged?
The nucleus of an atom is charged positively by the presence of protons
Which two scientist discovered particles that make up the nucleus?
Ernest Rutherford discovered protons in 1920, and James Chadwick discovered neutrons (which Rutherford postulated) in 1932. Each won a Nobel Prize for their contributions to nuclear physics.
Who discovered that protons exIst in the nucleus?
george roger dicovered this
Which scientist proposed the atom's nucleus contained protons and in what year?
It is the scientist Rutherford. He proposed it in year 1919.
Is the nucleus positive due to the neutrons?
No. Neutrons have a neutral charge. The nucleus is positive due to the presence of protons which have a positive charge.
What is the chemical symbol for the element with 133 and 197 protons in its nucleus?
Elements with 133 protons or 197 protons have not been discovered or named so far.
Who said Protons exist?
described best by rutherford. first to figure out the atomic nucleus.
Who was the first scientist to think protons and neutrons make up the nucleus of an atom?
Gould stien discovered the proton during discharge tube experiment and Chadwik discovered the neutron during the experiment about artificial radioactivity.
What charge is a nucleus?
neutral
What is the subatomic particle discovered by Chadwick?
In 1932, James Chadwick discovered the neutron. Neutrons help stabilize the protons in the atom's nucleus. Because the nucleus is so tightly packed together, the positively charged protons would tend to repel each other normally. Neutrons help to reduce the repulsion between protons and stabilize the atom's nucleus. Neutrons always reside in the nucleus of atoms and they are about the same size as protons. However, neutrons do not have any electrical charge; they are electrically neutral.
How long has it been that scientists have accepted that the nucleus of the atom consists of neutrons and protons?
Ernest Rutherford discovered protons in the nuclei of atoms in 1918, and James Chadwick discovered neutrons in 1932.
Who discovered the nucleus particles?
Electrons: J.J. Thompson Protons: Ernest RutherfordNeurtons: James Chadwick
