- Electrons are negatively charged particles.
- They revolve around the nucleus in various energy levels.
- They can be excited to higher energy levels by absorbing energy.
- Mass of electron is 1/2000 times of proton/neutron.
What are 3 characteristics of atoms?
Atoms consist of three basic particles:
protons, electrons, and neutrons
. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged).
What are 3 characteristics of protons?
- A Balanced Atom. Protons are located in an atom’s nucleus, which is a compact core in the center of the atom. …
- Proton Measurements. Protons have a minuscule yet nonzero mass. …
- A Stronger Force. …
- Donated Protons.
What are 3 characteristics of a neutron?
- Electrically neutral, they can go deep into matter. Neutrons are non-destructive and can penetrate deep into matter. …
- Microscopically magnetic, they can show magnetism. …
- Their energies of millielectronvolts can show motion.
What are the similarities and differences between protons neutrons and electrons?
Protons and neutrons have approximately the same mass
, but they are both much more massive than electrons (approximately 2,000 times as massive as an electron). The positive charge on a proton is equal in magnitude to the negative charge on an electron.
What color represents a neutron?
Neutrons are
green with no
charge.
How do atoms behave?
Electrons are attracted to any positive charge by their electric force; in an atom, electric forces bind the electrons to the nucleus. … In some respects, the electrons in an atom behave
like particles orbiting the nucleus
. In others, the electrons behave like waves frozen in position around the nucleus.
What are the 4 properties of the atom?
- Typical sizes of atom and nucleus.
- Most of atom’s mass is in the nucleus.
- Constituents: protons, neutrons, electrons.
- Electric force holds atom together.
- Nuclear force holds nucleus together.
- Atoms, ions.
- Atomic number.
Are humans made of atoms?
About 99 percent of your body is made up
of atoms of hydrogen, carbon, nitrogen and oxygen. You also contain much smaller amounts of the other elements that are essential for life. … The very heavy elements in you were made in exploding stars. The size of an atom is governed by the average location of its electrons.
What are the qualities of a neutron?
Neutron, neutral subatomic particle that is a constituent of every atomic nucleus except ordinary hydrogen. It
has no electric charge and a rest mass equal to 1.67493 × 10
− 27
kg
—marginally greater than that of the proton but nearly 1,839 times greater than that of the electron.
What are properties of a neutron?
Neutrons are
neutral particles – no net electric charge
. Neutrons have non-zero magnetic moment. Free neutrons (outside a nucleus) are unstable and decay via beta decay. The decay of the neutron involves the weak interaction and is associated with a quark transformation (a down quark is converted to an up quark).
What are 2 characteristics of a proton?
Protons-Protons are located in an atom’s nucleus, which is a compact core in the center of the atom. Most nuclei also contain neutrons. Perhaps the most essential characteristic of a proton is its
positive electrical charge
. Electrons-Electrons have three fundamental properties: charge, mass, and spin.
What are two properties that protons and electrons have in common?
What are two properties that protons and electrons have in common?
They are charged
. Protons are positively shared and electrons are negatively charged. Which two subatomic particles are nearly identical in mass?
What is the main difference between protons and electrons?
Electron Proton | The mass of an electron is 9.1 × 10 – 31 Kg. The mass of a proton is 1.67 × 10 – 27 Kg. | It can be easily added or removed from the atom. It is hard to be added or removed from the atom. | It is highly mobile. It is not mobile since they are present inside the nucleus. |

What are three differences between electrons and neutrons?
The difference between electron, proton and neutron is
the charge they carry
. Electrons are charged negative, protons are charged negative, and neutrons do not carry any charge. Rather they are neutral.
Who invented electron?
In 1897 Thomson discovered the electron and then went on to propose a model for the structure of the atom. His work also led to the invention of the mass spectrograph. The British physicist Joseph John (J. J.)
