What is it called when when two of the same element have a different mass?
Two atoms with the same atomic number, but different mass numbers (same number of protons, different number of neutrons), are called isotopes, or isotopic nuclides. Having different numbers of neutrons changes the mass of these atoms, so isotopes have slight variations in their physical and chemical behavior.
What is it called when two of the same atoms are bonded together?
Explanation: A compound is “a substance formed when two or more chemical elements are chemically bonded together.” There are two main types of chemical bonds: covalent and ionic.
What is isotope give example?
The number of nucleons (both protons and neutrons) in the nucleus is the atom’s mass number, and each isotope of a given element has a different mass number. For example, carbon-12, carbon-13, and carbon-14 are three isotopes of the element carbon with mass numbers 12, 13, and 14, respectively.
What does Isotones mean?
Isotones are atomic species that share the same number of neutrons and differ in the number of protons. Examples of isotones include carbon-12, nitrogen-13 and oxygen-14. same A (number of nucleons) = isobars. same N (number of neutrons) = isotones.
Which two atoms have the same mass?
Atoms of an element with the same mass number make up an isotope of the element. Different isotopes of the same element cannot have the same mass number, but isotopes of different elements often do have the same mass number, e.g., carbon-14 (6 protons and 8 neutrons) and nitrogen-14 (7 protons and 7 neutrons).
What are 2 examples of isotopes?
Isotope Examples Carbon 12 and Carbon 14 are both isotopes of carbon, one with 6 neutrons and one with 8 neutrons (both with 6 protons). Carbon-12 is a stable isotope, while carbon-14 is a radioactive isotope (radioisotope). Uranium-235 and uranium-238 occur naturally in the Earth’s crust. Both have long half-lives.
What are the two main properties of matter?
Matter can be defined or described as anything that takes up space, and it is composed of miniscule particles called atoms. It must display the two properties of mass and volume.
What is a group of 4 atoms called?
When atoms join together, the group is called a molecule. The atoms in a molecule can the the same.
What is an isotope easy definition?
isotope, one of two or more species of atoms of a chemical element with the same atomic number and position in the periodic table and nearly identical chemical behaviour but with different atomic masses and physical properties. Every chemical element has one or more isotopes.
Are Isodiaphers and isotones same?
In similar manner, a set of nuclides with equal mass number A, but different atomic number, are called isobars (isobar = equal in weight), and isotones are nuclides of equal neutron number but different proton numbers. Likewise, nuclides with the same neutron excess (N − Z) are called isodiaphers.
Which two has the same mass number?
The two subatomic particles that have the same mass are protons and neutrons.
Can 2 elements have the same mass?
Different isotopes of the same element cannot have the same mass number, but isotopes of different elements often do have the same mass number, e.g., carbon-14 (6 protons and 8 neutrons) and nitrogen-14 (7 protons and 7 neutrons).
Which is a compound composed of more than one element?
A substance that can be broken down into chemically simpler components (because it has more than one element) is a compound (Figure 1.4. 1). Water is a compound composed of the elements hydrogen and oxygen. Today, there are 118 elements in the known universe. In contrast, scientists have identified tens of millions of different compounds to date.
What happens when you combine elements with specific numbers?
When those pieces start combining in specific numbers, you can build atoms with recognizable traits. If you have eight protons, neutrons and electrons, you will have an oxygen (O) atom. If you have seven protons, neutrons, and electrons, you will have a nitrogen (N) atom.
Are there any elements that are the same on Earth?
Iron (Fe) atoms found on Earth are identical to iron atoms found on meteorites. The iron atoms in the red soil of Mars are also the same. With the tools you learn here, you can explore and understand the Universe. You will never stop discovering new reactions and compounds, but the elements will be the same.
Which is an element that cannot be broken down into simpler components?
A substance that cannot be broken down into chemically simpler components is an element. Aluminum, which is used in soda cans, is an element. A substance that can be broken down into chemically simpler components (because it has more than one element) is a compound (Figure 1.4. 1 ). Water is a compound composed of the elements hydrogen and oxygen.
