What property of an atom determines which element it is quizlet?
Remember that the number of protons in the nucleus determines an element's identity. Chemical changes do not affect the nucleus, so chemical changes cannot change one type of atom into another. … The identity of the atom, therefore, changes. Recall that the nucleus of an atom contains protons and neutrons.
What determines the property 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 property of an atom allows you to determine which element it is on the periodic table?
Atomic number: The number of protons in an atom's nucleus is referred to as the atomic number of that element. The number of protons defines what element it is and also determines the chemical behavior of the element.
What do the properties of atoms determine?
A neutral atom has an equal number of protons and electrons so that the positive and negative charges exactly balance. Since it is the electrons that determine how one atom interacts with another, in the end it is the number of protons in the nucleus that determines the chemical properties of an atom.
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.
Which property determines the chemical reactivity of an element?
The number of electrons in the outermost shell of an atom determines its reactivity.
How do you identify an element?
There are two properties that can be used to identify an element: the atomic number or the number of protons in an atom. The number of neutrons and number of electrons are frequently equal to the number of protons, but can vary depending on the atom in question.
What makes an element an element?
chemical element, also called element, any substance that cannot be decomposed into simpler substances by ordinary chemical processes. Elements are the fundamental materials of which all matter is composed.
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 determines an element to pair up with other atom?
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 number in an atom defines the element it belongs to?
The number of protons in the nucleus of an atom determines an element's atomic number. In other words, each element has a unique number that identifies how many protons are in one atom of that element.
Which of these particles determines the element’s identity?
1 Answer. The proton determines the identity of an element.
What determines the chemical behavior of an element?
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.
What are three ways to identify an element?

How do you classify elements?
Periodic Classification of Elements Characteristics In the long form periodic table the elements are arranged in the order of their atomic numbers. Atomic number of an element is equal to the number of protons inside the nucleus of its atom.
What defines an element quizlet?
Element. A pure substance that cannot be broken down into any other substances because it consists of only one type of atom.
What determines the atomic number of an element?
number of protons The atomic number is the number of protons in the nucleus of an atom. The number of protons define the identity of an element (i.e., an element with 6 protons is a carbon atom, no matter how many neutrons may be present).
What property in the structure of atom makes each element different from the others?
Atoms of each element contain a characteristic number of protons and electrons. The number of protons determines an element's atomic number and is used to distinguish one element from another.
What makes the atoms of one element different from the other?
The number of protons gives the atomic number. We know that every chemical element has its own atomic number. Thus, the atom of one element differs from another element's atom by the number of protons.
How do you know which atom is which?

How do you determine an element?
There are two properties that can be used to identify an element: the atomic number or the number of protons in an atom. The number of neutrons and number of electrons are frequently equal to the number of protons, but can vary depending on the atom in question.
How do you identify elements and compounds?
Elements contain only one type of atom. Each atom has the same atomic number i.e., the same number of protons in their nucleus. A compound can be separated into simpler substances by chemical methods/reactions. Elements cannot be broken down into simpler substances by chemical reactions.
What is true about an element quizlet?
What is true about elements? Each element has a unique atomic number.
Is the number of protons in the nucleus of an atom which determines the chemical properties of an element and its place in the periodic table?
atomic number The atomic number is the number of protons in the nucleus of an atom. The number of protons define the identity of an element (i.e., an element with 6 protons is a carbon atom, no matter how many neutrons may be present).
What determines the atomic number of an atom quizlet?
Step 1. The atomic number of an atom is determined by the number of protons.
What determines the atomic mass or mass number of an element?
The mass number (represented by the letter A) is defined as the total number of protons and neutrons in an atom.
What causes an atom to become a different element?
Since the number of protons in the nucleus of an atom determines the element, the conversion of a neutron to a proton actually changes the radioactive element (radionuclide) to a different element. The speed of individual beta particles depends on how much energy they have, and varies widely.
What is true about an element?
An element is a substance that is made entirely from one type of atom. For example, the element hydrogen is made from atoms containing a single proton and a single electron. If you change the number of protons an atom has, you change the type of element it is.
What is an element quizlet?
Element. A pure substance that cannot be broken down into any other substances because it consists of only one type of atom.
How are properties of elements are determined by the atomic structure?
An atom is composed of a nucleus and electrons that go around the former. The nucleus is composed of protons with a positive charge and neutrons without charge, and the number of protons (atomic number) determines the chemical properties of the atom (element type).
