Basic principles. Isotopes are atoms of the same element that have different numbers of neutrons but the same number of protons and electrons. The difference in the number of neutrons between the various isotopes of an element means that the various isotopes have different masses .
What two things are different about isotopes of the same element Brainly?
Isotopes of the same element will have the same atomic number but different mass numbers . Atomic number, chemical symbol, and mass numberCarbon has an atomic number of six, and two stable isotopes with mass numbers of twelve and thirteen, respectively. Its average atomic mass is 12.11.
Which option describes a similarity and a difference between isotopes of an element?
Answer Expert Verified ‘which option describes a similarity between isotopes of an element. The correct option is C. Isotopes have the same number of atomic number but different mass number.
What is different in isotopes for an element?
Isotopes are members of a family of an element that all have the same number of protons but different numbers of neutrons . The number of protons in a nucleus determines the element's atomic number on the Periodic Table. ... The addition of even one neutron can dramatically change an isotope's properties.
How do you read an isotope symbol?
To write the symbol for an isotope, place the atomic number as a subscript and the mass number (protons plus neutrons) as a superscript to the left of the atomic symbol. The symbols for the two naturally occurring isotopes of chlorine are written as follows: 3517Cl and 3717Cl.
In what cases are differences between isotopes important?
Isotopes of an element all have the same chemical behavior, but the unstable isotopes undergo spontaneous decay during which they emit radiation and achieve a stable state. This property of radioisotopes is useful in food preservation , archaeological dating of artifacts and medical diagnosis and treatment.
What 3 things do isotopes of the same element have in common?
Isotopes of an element share the same number of protons but have different numbers of neutrons . Let's use carbon as an example. There are three isotopes of carbon found in nature – carbon-12, carbon-13, and carbon-14. All three have six protons, but their neutron numbers – 6, 7, and 8, respectively – all differ.
What are the difference among the different element?
A particular element is composed of only one type of atom. Atoms are further composed of subatomic particles called electrons, protons and neutrons. Elements can combine with each other to form molecules via chemical reaction. ... Elements are bigger and heavier and mass .
How do you make a distinction between all isotopes of the same element?
all isotopes have the same number of protons and the same number of electrons . Because the electron structure is the same isotopes have the same chemical properties. What is different is the number of neutrons, The different number of neutrons all cause a difference in the atomic weight or mass of the atoms.
Is carbon 13 a radioactive isotope?
FIVE isotopic forms of the element carbon are known, having atomic weights ranging from 10 to 14. Two of them, C 12 and C 13 , exist stably in Nature, while the others are radioactive , and are known to us only through their production in various nuclear reactions.
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 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 is the symbol of uranium?
Uranium is in the periodic table that has a symbol U and atomic number 92. It also has the highest atomic weight of the naturally occurring elements. Uranium is atomic number 92 and can have different numbers of neutrons in the nucleus from 141 to 146.
What is an isotopic symbol?
Isotope notation, also known as nuclear notation, is important because it allows us to use a visual symbol to easily determine an isotope's mass number, atomic number, and to determine the number of neutrons and protons in the nucleus without having to use a lot of words.
What does the top number mean in an isotope?
In elemental notation, the atomic number is found at the bottom left corner of the chemical symbol for the element. The upper number represents the nuclear mass of the atom , given by the sum of the protons and neutrons.
What is the importance of isotopes in our daily life?
Radioactive isotopes have many useful applications. In medicine, for example, cobalt-60 is extensively employed as a radiation source to arrest the development of cancer. Other radioactive isotopes are used as tracers for diagnostic purposes as well as in research on metabolic processes.
