What distinguishes the atoms of one element from the atoms of another quizlet?
The number of protons distinguishes the atoms of one element from those of another.
What distinguishes one atom of an element from other atoms?
The number of protons in an atom determines what element you have.
What distinguishes one isotope from another?
Isotopes. An isotope is one of two or more forms of the same chemical element. Different isotopes of an element have the same number of protons in the nucleus, giving them the same atomic number, but a different number of neutrons giving each elemental isotope a different atomic weight.
What distinguishes one isotope from another quizlet?
How do isotopes of a given element differ from one another? They have different mass numbers and different numbers of neutrons.
What are the differences among the different elements?
Comparison chart
| Element | |
|---|---|
| Composition | Elements contain only one type of atom. Each atom has the same atomic number i.e., the same number of protons in their nucleus. |
| Ability to break down | Elements cannot be broken down into simpler substances by chemical reactions. |
| Representation | An element is represented using symbols. |
How do the isotopes of a given element differ from one another quizlet?
How do isotopes of a given element differ from one another? They have different mass numbers and different numbers of neutrons.
What is the difference between isotopes and atom?
Isotopes are atoms with different atomic masses which have the same atomic number. The atoms of different isotopes are atoms of the same chemical element; they differ in the number of neutrons in the nucleus.
How do you distinguish isotopes?
Answer:
- The difference between different isotopes of the same element is based on their masses.
- Mass is used as a parameter to differentiate as the number of neutrons present in the isotopes varies based on their mass. This is a way to differentiate between isotopes.
How do you find the atoms of different elements apart?
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 can you tell atoms apart?
Two atoms of the same element can be different if their electrons are in different states. If one copper atom has an electron in an excited state and another copper atom has all of its electrons in the ground state, then the two atoms are different.

What determines the identity of an atom?
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 is the difference between atom and element with example?
A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons. An element is a substance that is made entirely from one type of atom. For example, the element hydrogen is made from atoms containing just one proton and one electron.
How are atoms of the same element similar and different from one another?
Atoms of the same element consist of the same atomic number that is number of protons or electrons and different mass number that is number of neutrons. This variation or change in the number of neutrons in an atom gives rise to different isotopes of an element.
What determines the identity of an element?
The proton determines the identity of an element.
Which statement about one atom of an element identifies the element?
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. For example, all hydrogen atoms, and only hydrogen atoms, contain one proton and have an atomic number of 1.
What determines the identity of an atom quizlet?
The identity of the atom is determined by the number of protons; an atom with five protons has different properties than an atom with six protons. small mass. We use a very small unit of mass to measure them, and this unit is called an atomic mass unit (amu).
What determines the characteristics of an element?
Answer: Factors such as the symbol of the element, atomic number and atomic mass determine the characteristics of an element. Answer: The atoms of all the elements are made up of electrons, protons and neutrons.
What’s the difference between an element?
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.
How do you know the atoms of an element?
So, if you are given the mass of an element, you use the periodic table to find its molar mass, and multiply the given mass by the reciprocal of the molar mass. This is Mass → Moles . Once you have moles, multiply by Avogadro's number to calculate the number of atoms. This is Moles → Atoms .
What determines identity of an element?
Correct answer: The identity of an element is determined by the number of protons. One cannot alter the number of protons without altering the identity of the element. By adding a proton, the atomic number increases by one and the element identity changes. Number of neutrons can be altered to create isotopes.
What describes all atoms of one element?
All atoms of an element have the same number of protons, and every element has a different number of protons in its atoms. For example, all helium atoms have two protons, and no other elements have atoms with two protons.
What is the difference between atoms elements and molecules?
You know elements are all the different types of atoms on the periodic table. Molecules are what you get when those atoms are combined. Unlike elements, molecules can be made from the same or different elements. The key to a molecule is that two or more atoms are bonded together.
What are the differences between atoms elements molecules and compounds?

What is the common characteristic of all atoms of elements?
The fundamental characteristic that all atoms of the same element share is the number of protons. All atoms of hydrogen have one and only one proton in the nucleus; all atoms of iron have 26 protons in the nucleus.
What are the differences among the different element?
Isotopes of the same elements differ in their atomic masses. Isotopes – isotopes of an element have the same number of protons in their nucleus but differ in the number of neutrons. Naturally occurring elements have more than one stable isotope.
How are atoms of the same similar element different from one another what do you call these atoms?
Isotopes are atoms with different atomic masses which have the same atomic number. The atoms of different isotopes are atoms of the same chemical element; they differ in the number of neutrons in the nucleus.
How can you distinguish a molecule from an element?
Molecule is a substance with two or more atoms bonded together such as the oxygen humans breathe (O2). Elements are pure substances made up of all the same atoms such as gold (Au), hydrogen (H), and oxygen (O). Elements all have the same number of protons in their nuclei and can't be broken down.
How can you distinguish between atoms molecules and ions?
Atoms are single neutral particles. Molecules are neutral particles made of two or more atoms bonded together. An ion is a positively or negatively charged particle.
What makes an element distinct?
But, atoms themselves contain many subatomic particles, the three most important of which are protons, neutrons, and electrons. These particles do not vary in quality from one element to another; rather, what gives an element its distinctive identification is the quantity of its protons, called its atomic number.
