What determines the chemical properties of an atom quizlet?
The chemical properties of an element, are determined by the number of protons in the nucleus. This number of protons is called the atomic number. The mass of the atom, its atomic mass, depends upon the sum of the number of protons and the number of neutrons present in the nucleus.

What determines chemical property elements?
Valence electrons determine the chemical properties of an element, or how the valence electrons of one element are shared or traded with valence electrons of other elements to create new molecules.
Which determines the chemical behavior of an atom?
The chemical behavior of atoms is determined by the number and the configuration of the electrons in the atom. Why should one bother to discuss the nucleus? The number of protons in the nucleus determines the number of electrons in the atom. Most atoms in the world around us are electrically neutral.
What determines the type of atom?
The primary sub-atomic particle is the proton, because the number of protons inside an atom determines which type of atom it is. For example, all atoms that have 8 protons in the nucleus are oxygen atoms. All atoms that have 6 protons are carbon atoms.
Do protons determine chemical properties?
The number of protons along with the neutrons will help to determine the mass number of the chemical element. The number of protons will determine the number of the electrons present. This electron will determine the chemical properties of the element.
Which is chemical property?
A chemical property is a characteristic of a particular substance that can be observed in a chemical reaction. Some major chemical properties include flammability, toxicity, heat of combustion, pH value, rate of radioactive decay, and chemical stability.
How do protons determine the chemical properties of an atom?
The number of protons will determine the number of the electrons present. This electron will determine the chemical properties of the element. The chemical properties of an atom will depend on the number of valence electrons present. Depending on the valence electrons, the atom will form positive or negative ions.
What particle determines the chemistry of an atom?
protons The number of protons inside a nucleus must equal to the number of electrons outside of the nucleus. This number determines all the chemical properties of the atom, which governs the behaviors of all matters in our world.
Why do electrons determine the properties of an atom?
The number of protons will determine the number of the electrons present. This electron will determine the chemical properties of the element. The chemical properties of an atom will depend on the number of valence electrons present. Depending on the valence electrons, the atom will form positive or negative ions.
How do neutrons determine the properties of an atom?
The number of protons along with the neutrons will help to determine the mass number of the chemical element. The number of protons will determine the number of the electrons present. This electron will determine the chemical properties of the element.
What type of force holds the nucleus of an atom together?
the nuclear force The force that holds a nucleus together is the nuclear force, a short-range force between nucleons. At very small separations, the nuclear force is repulsive, keeping the protons and neutrons from getting too close to one another.
What determines an atom’s chemical behavior?
The chemical behavior of atoms is determined by the number and the configuration of the electrons in the atom. Why should one bother to discuss the nucleus? The number of protons in the nucleus determines the number of electrons in the atom. Most atoms in the world around us are electrically neutral.
What is a chemical property quizlet?
Chemical Property Definition. A characteristic that can only be observed during a chemical reaction and involves changing the substance into another substance.
What is chemical property matter?
Chemical properties are properties that can be measured or observed only when matter undergoes a change to become an entirely different kind of matter. They include reactivity, flammability, and the ability to rust. Reactivity is the ability of matter to react chemically with other substances.
What determines an atom’s identity and chemical properties?
Explanation: The number of electrons, in turn, determines the chemical properties of the atom. Protons contribute to the mass of an atom and provide the positive charge to the nucleus. The number of protons also determines the identity of the element.
What determines the chemical behavior of atoms?
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).
Which of the following determines the chemical behavior of atoms?
Chemical behaviour of an atom is determined by its atomic number.
Which force binds atoms together?
The strong nuclear force is a very strong, attractive short-range (10-15 m) force that binds the protons and neutrons in the nuclei of atoms together.
Which is a force that holds atoms together quizlet?
A chemical bond is the force that holds the atoms of a molecules together, as in a compound. A chemical bond is an electrical force linking atoms.
Which of the following is a chemical property?
Examples of chemical properties include flammability, toxicity, acidity, reactivity (many types), and heat of combustion.
Which property is a chemical property of a substance quizlet?
Examples of chemical properties include reactivity, flammability and oxidation states.
What are atoms determined by?
The number of protons in the nucleus, known as the "atomic number," primarily determines where that atom fits on the Periodic Table. The number of protons in the nucleus also defines in large part the characteristics of an atom—is it a gas or a metal, for example.
What is the strong force in an atom?
The strong force is 'felt' between nucleons (protons and neutrons) inside of the nucleus of an atom. The strong nuclear force is sometimes referred to as just the strong force or the strong interaction.
What is the electromagnetic force in an atom?
Electromagnetic Force of Attraction: exists between negative electrons and positive protons in the nucleus and keeps electrons in the area surrounding the nucleus. Electromagnetic Force of Repulsion: exists between positive protons in the nucleus is overcome by the strong nuclear force between protons and neutrons.
What force holds atoms together?
– The basic force that holds all the atoms together in a molecule is known as strong nuclear force. – Nuclear forces are the strongest attractive forces that make the molecule exist in nature.
What holds atoms together in a chemical bond?
Chemical bond refers to the forces holding atoms together to form molecules and solids. This force is of an electric nature, and the attraction between electrons of one atom to the nucleus of another atom contributes to what is known as chemical bonds.
Which of the following is a chemical property quizlet?
Chemical properties include flammability, reactivity, heat of combustion, and toxicity.
Which of the following is a chemical property of a substance quizlet?
Step 1. The correct answer is D. A chemical property is the substance's ability to transform into a new substance that contains different properties. Burning, which is also known as combustion, causes a new substance to be formed.
What are chemical properties quizlet?
Chemical properties of a substance describe which chemical changes will occur and which chemical changes will not occur. But chemical changes are the process by which substances actually change into new substances.
