The two subatomic particles that are attracted to each other are protons and electrons. Protons are positively charged subatomic particles located in…
Which two subatomic particles are attracted to one another and why?
Unlike protons and neutrons, which are located inside the nucleus at the center of the atom, electrons are found outside the nucleus. Because opposite electric charges attract each other, negative electrons are attracted to the positive nucleus.
What two subatomic particles repel each other?
Protons and Neutrons
Protons have a positive electrical charge, so they are often represented with the mark of a “+” sign. Neutrons have no electrical charge and are said to help hold the protons together since protons are positively charged particles and should repel each other.
Which two subatomic particles are attracted to each other like magnets?
So, much like opposite ends of a magnet, protons and electrons are attracted to each other. Likewise, just as when you experience resistance trying to push the same ends of two magnets together, protons are repelled from other protons and electrons are repelled from other electrons.
Which particles contribute to the mass number and which do not why?
Which particles contribute to the mass number and which do not? Why? Electrons do not affect the mass number but neutrons and protons do. Electrons do not have a mass.
What two particles in an atom are attracted to each other?
The protons and electrons of an atom are attracted to each other. They both carry an electrical charge. Protons have a positive charge (+) and electrons have a negative charge (-). The positive charge of the protons is equal to the negative charge of the electrons.
Which particles would be attracted to each other *?
electrons and protons. Opposite charges attract each other.
Which of the following are subatomic particles?
Subatomic particles include electrons, the negatively charged, almost massless particles that nevertheless account for most of the size of the atom, and they include the heavier building blocks of the small but very dense nucleus of the atom, the positively charged protons and the electrically neutral neutrons.
What holds subatomic particles together?
The strong force binds quarks together within protons, neutrons, and other subatomic particles. Rather as the electromagnetic force is ultimately responsible for holding bulk matter together, so the strong force also keeps protons and neutrons together within atomic nuclei.
What objects are attracted to magnets?
Magnets attract, or pull, objects made with iron.
Paper clips, scissors, screws, nuts, and bolts are just a few common everyday objects that are magnetic. A magnet will not attract paper, rubber, wood, or plastic. It is not true that a magnet will attract any kind of metal.
Are all metals attracted to magnets?
Magnetic materials are always made of metal, but not all metals are magnetic. Iron is magnetic, so any metal with iron in it will be attracted to a magnet. … Most other metals, for example aluminium, copper and gold, are NOT magnetic.
Why do magnets attract metal?
Magnets attract iron due to the influence of their magnetic field upon the iron. … When exposed to the magnetic field, the atoms begin to align their electrons with the flow of the magnetic field, which makes the iron magnetized as well. This, in turn, creates an attraction between the two magnetized objects.
What subatomic particles have mass?
Protons are positively charged particles, have mass, and are located in the center, or nucleus of the atom. Neutrons have no charge, have mass, and are also located in the nucleus of the atom.
Which subatomic particles makes up most of the mass of the atom?
The majority of an atoms’ mass comes from the protons and neutrons that make up its nucleus. Electrons are the least massive of an atom’s constituent particles, with a mass of 9.11 x 10–31 kg and a size too small to be measured by current techniques.
Which subatomic particles contribute most to the atomic mass and mass number?
Protons are massive particles with unit positive electric charge; neutrons are massive particles with NO electric charge. Together these constitute MOST (>99.9%) of the mass of the atom.
