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.
Who was the first scientist to think protons and neutrons make up the nucleus of an atom?
Ernest Rutherford was the first scientist to propose that protons reside in the nucleus of an atom, based on his gold foil experiment in 1911. Neutrons were later discovered by James Chadwick in 1932.
Who was the scientist that showed existence of the nucleus?
Ernest Rutherford was the scientist who demonstrated the existence of the atomic nucleus through his famous gold foil experiment in 1909. He discovered that atoms have a small, dense core at their center that contains positively charged particles which he named protons.
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.
The nucleus of an atom is charged?
True. The nucleus of an atom is charged positively due to the presence of protons, which have a positive charge. The overall charge of the nucleus is balanced by the negatively charged electrons that orbit around it.
Which scientist proposed the atom's nucleus contained protons and in what year?
It is the scientist Rutherford. He proposed it in year 1919.
What is the charge on the necleus?
The nucleus of an atom carries a positive charge due to the presence of protons, which have a charge of +1. The number of protons in the nucleus determines the overall charge of the nucleus.
Who is name discovered to atomic number?
The concept of atomic number was discovered by the scientist Henry Moseley in 1913. He found that the number of protons in an atom's nucleus determines its identity, which led to the organization of the periodic table based on atomic number.
Which two scientist discovered particles that make up the nucleus?
Ernest Rutherford and his team conducted the gold foil experiment, which led to the discovery of the positively charged nucleus in atoms. James Chadwick then discovered the neutron as a neutral particle within the nucleus.
Is the nucleus of there atoms positive negative or neutral?
inside the nucleus there are protons which are positive and neutrons that are neutral, because the neutrons are neutral they don't affect the charge. so the Nucleus is Positive.
Atoms consist of a nucleus containing?
protons and neutrons, surrounded by electrons. The nucleus holds the majority of the atom's mass due to the presence of protons and neutrons, while electrons orbit around the nucleus in specific energy levels. The number of protons in the nucleus determines the element's identity, while the balance of protons and electrons gives the atom its 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.
What does a nucleus mean in science?
In science, a nucleus refers to the central part of an atom that contains protons and neutrons. It is the dense core of an atom where the majority of its mass is concentrated. The nucleus is positively charged due to the presence of protons.
