What subatomic particle determines the chemical behavior of an atom?

What subatomic particle determines the chemical behavior of an atom?

electrons
Its chemical behavior is determined by the atomic number 2 (the number of protons), which equals the normal number of electrons; the stability of its nucleus (that is, its radioactivity) varies with its atomic weight (approximately equal to the number of protons and neutrons).

What are the 3 subatomic particles of an atom and describe them?

Protons, neutrons, and electrons are the three main subatomic particles found in an atom. Protons have a positive (+) charge. An easy way to remember this is to remember that both proton and positive start with the letter “P.” Neutrons have no electrical charge.

What determines an atom’s reactivity Brainly?

The number of electrons in the outermost shell of an atom determines its reactivity.

Which subatomic particle determines the element’s identity?

protons
The number of protons determines the element of the atom, the number of neutrons determines the isotope, and the number of electrons determines the ionization state. Answer 4: I would say the proton is the “boss,” since the number of protons determines the atomic number and therefore the chemical identity of the atom.

What determines an atoms reactivity when it is around other atoms?

The number of electrons in the outermost shell of a particular atom determines its reactivity, or tendency to form chemical bonds with other atoms.

What are the three types of subatomic particles?

Subatomic particles are particles of matter smaller than an atom. These particles help to make the atoms that compose everything around us. The three basic types of subatomic particles are protons, neutrons, and electrons. Become a Study.com member to unlock this answer!

Which is subatomic particle determines the chemical properties of an atom?

What subatomic particle determines the chemical properties of an atom? The subatomic particle, of course, is the electron, which orbit the nucleus of the atom by traveling in energy levels, two in the first, 6 in the second, and 10 in the third.

Which is the smallest particle of an atom?

Elementary and Subatomic Particles The three main subatomic particles of an atom are protons, neutrons, and electrons. Mats Persson / Getty Images The atom is the smallest particle of matter than cannot be divided using a chemical means, but atoms consist of smaller pieces, called subatomic particles.

What did J J Thomson discover about subatomic particles?

He named these particles as electrons. J.J Thomson’s atomic model, also known as plum pudding model identified the existence of electrons as the subatomic particles. Thomson made precise calculations for the mass and charge on an electron and is credited with the discovery of electrons.
