Which part of an atom determines its chemical behavior?
The position of the outermost electrons is key in determining the behavior of an atom.
What is the part of an atom that determines the chemical identity of an atom of an element?
The number of protons in the nucleus of an atom is its atomic number (Z). This is the defining trait of an element: Its value determines the identity of the atom. For example, any atom that contains six protons is the element carbon and has the atomic number 6, regardless of how many neutrons or electrons it may have.
What part of the atom affects chemical properties?
The chemical properties of the atom are determined by the number of protons, in fact, by the number and arrangement of electrons. The configuration of these electrons follows the principles of quantum mechanics.
What determines an element’s chemical properties?
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.
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 properties of an element?
The chemical properties of an element are determined by the number of electrons in its atom, which in turn is determined by the number of protons.
What determines the chemical properties of an element?
The chemical properties of an element are determined by the number of electrons in its atom, which in turn is determined by the number of protons.
Which property determines the chemical reactivity of an element?
The number of electrons in the outermost shell of an atom determines its reactivity.
How electrons determine the chemical properties of atoms?
Electrons located in the outermost shell of the electron cloud are called “valence electrons” and have the highest energy. Valence electrons determine the chemical properties of an element.
What determines the chemical element?
An element is defined by its number of protons. Varying the number of neutrons will change the isotope of an element and varying the number of electrons will create an ion, but changing the number of protons changes the identity of the element itself.
What determines the chemical properties and physical properties of a mineral?
Together, the chemical formula (the types and proportions of the chemical elements) and the crystal lattice (the geometry of how the atoms are arranged and bonded together) determine the physical properties of minerals.
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.
What determines an element’s chemical properties 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 is the chemical property of element?
Chemical properties describe the characteristic ability of a substance to react to form new substances; they include its flammability and susceptibility to corrosion. All samples of a pure substance have the same chemical and physical properties.
What determines the chemical properties of minerals?
Together, the chemical formula (the types and proportions of the chemical elements) and the crystal lattice (the geometry of how the atoms are arranged and bonded together) determine the physical properties of minerals.
What are minerals chemical properties determined by?
Properties that help geologists identify a mineral in a rock are: color, hardness, luster, crystal forms, density, and cleavage. Crystal form, cleavage, and hardness are determined primarily by the crystal structure at the atomic level. Color and density are determined primarily by the chemical composition.
What determines the chemical behavior of an atom quizlet?
The chemical behavior of an atom is determined by the distribution of electrons in electron shells.
How do you identify chemical properties?
To identify a chemical property, we look for a chemical change. A chemical change always produces one or more types of matter that differ from the matter sspresent before the change.
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 statement describes a chemical property?
The correct option is (d), Reacting with hydrogen to form a gas is an example of a chemical property.
Which of the following subatomic particles determines the chemical element quizlet?
An atom that has the same number of protons but a different number of neutrons. Which subatomic particle determines the identity of an element? Protons.
Which parts of atoms can interact react to form chemical bonds?
Which parts of atoms can interact (react) to form chemical bonds? valence electrons; Only the outermost parts of atoms interact (react) with each other, and those are the valence electrons. If the outermost orbital is full, the atom is stable and less likely to react with another atom.
What determines the chemical properties of matter?
Chemical properties of matter describe its potential to undergo some chemical change or reaction by virtue of its composition. The elements, electrons, and bonds that are present give the matter potential for chemical change. It is quite difficult to define a chemical property without using the word "change".
What factors determine an element’s chemical properties?
The chemical properties of an element are determined by the number of electrons in its atom, which in turn is determined by the number of protons.
Which of the following is a chemical property of an element?
Examples of chemical properties include flammability, toxicity, acidity, reactivity (many types), and heat of combustion.
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.
Why do atoms form chemical bond?
Why form chemical bonds? The basic answer is that atoms are trying to reach the most stable (lowest-energy) state that they can. Many atoms become stable when their valence shell is filled with electrons or when they satisfy the octet rule (by having eight valence electrons).
Why do atoms form chemical bonds quizlet?
Why do atoms form chemical bonds? They want a full outer shell of electrons, so they lose, gain, or share electrons with other elements, forming compounds, until they have 8 valence electrons and become stable.
What determines chemical and physical properties?
A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. Physical properties include color, density, hardness, and melting and boiling points. A chemical property describes the ability of a substance to undergo a specific chemical change.
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.
