Why do isotopes of the same element have the same chemical properties?
Different isotopes of an element generally have the same physical and chemical properties because they have the same numbers of protons and electrons.
Why do isotopes have different names?
The term isotope is formed from the Greek roots isos (ἴσος “equal”) and topos (τόπος “place”), meaning “the same place”; thus, the meaning behind the name is that different isotopes of a single element occupy the same position on the periodic table.
Why do two isotopes of an element have the same atomic number but different mass numbers?
Isotopes of any given element all contain the same number of protons, so they have the same atomic number (for example, the atomic number of helium is always 2). Isotopes of a given element contain different numbers of neutrons, therefore, different isotopes have different mass numbers.
Why do the isotopes of the same element have the same atomic size?
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 are isotopes Why do isotopes show similar chemical properties but they differ in physical properties?
Isotopes have similar chemical properties because they have same number of valence electrons and have different physical properties, such as boiling point, melting point etc., because they have different mass numbers.
Which atoms represent different isotopes of the same element?
CHEMISTRY REGENTS: ISOTOPES INTRODUCTION: An isotope is an atom which contains a different number of neutrons in its nucleus than some other atom of the same element. This means that different isotopes of an element will have the same number of protons.
Do isotopes have different names?
Hydrogen is the only element whose isotopes have different names that are in common use today. Names used to be given to isotopes before we fully understood the atomic structure.
Which of the following is the same for isotopes of an element?
Isotopes are atoms of the same element that have the same number of protons but a different number of neutrons. Therefore, isotopes have the same atomic number (number of protons) but a different mass number (number of protons plus number of neutrons).
Do isotopes that have the same atomic number have the same atomic mass?
Protons and neutrons both weigh about one atomic mass unit or amu. Isotopes of the same element will have the same atomic number but different mass numbers.
Why do two isotopes of an element have the same atomic number but different mass numbers quizlet?
Why do two isotopes of an element have the same atomic number but different mass numbers? Isotopes of an element have the same number of protons (the same atomic number), but have a different numbers of neutrons. What are the three types of particles, and their charge, that can be found in an atom?
How are isotopes of the same element alike and different?
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.
How are isotopes of the same element alike quizlet?
how are isotopes of a particular element alike? The number of protons in that element.
