Which Property of the Isotopes Must Be Different

It asks for what MUST be different not. For example it takes 153 years for half of a sample of silicon.

Pic 1 Radiation Definition Of Radioactivity The Property Possessed By A Number Of The Elements As Like Uranium Radioactive Radiation Physical Science

Some isotopes of elements are unstable and decay into other more stable isotopes over time.

. All three isotopes of hydrogen have identical chemical properties. All 3 isotopes shown here have the same number of electrons and hence it would have similar chemical properties. The property of the isotopes must be different is the mass number.

From the above definition of atomic mass and the atomic number we can conclude that isotopes are those elements having the same atomic number and different mass number. Isotopes of an element have different physical properties because they have different mass numbers. Since the isotopes have different number of neutrons their masses would be different and hence.

This is because isotopes are defined for same atoms. Hydrogen and deuterium are isotopes. An atom of the element zinc has an atomic number of 30 and a mass number of 65.

The answer to this question is D the mass number. Which property of the isotopes must be different. Isotopes must have the same mass numbers.

Different isotopes of an element generally have the same physical and chemical properties. Isotopes are defined for same atoms. The physical properties of any isotope are largely determined by its mass.

An isotope only changes the amount of neutrons not the amount of protons. Carbon-12 and carbon-14 are isotopes. Chemical properties of different isotopes are almost similar.

Because of that they have similar chemical properties. Isotopes must have the same number of protons. If an atom has same number of protons and same number of electrons but different number of neutrons in it then such pair of atoms is known as isotopes.

Isotopes must have the same mass numbers. This is because the number of electrons determines chemical properties and all three isotopes have one electron in their atoms. Different isotopes of an element generally have the same physical and chemical properties.

However they have different numbers of neutrons which affects the mass number. Physical properties of an isotopes like mass melting or boiling point density and freezing point are different and depends on the mass of each isotope. The physical properties of the isotopes differ due to different mass numbers.

July 24 2021 at 1041 am. What can be added to an atom to cause a nonvalence electron in the atom to temporarily become a valence electron. Which property of the isotopes must be different.

Thats because they have the same numbers of protons and electrons. For example it takes 153 years for half of a sample of silicon Si atoms with 14. Isotopes are atoms that have different numbers of neutrons but the same number of protons.

Mass number determines the physical properties such as boilingmeltingdensity etc. Since atomic number is same so we can say that total charge of the two atoms must be same. For example it takes 153 years for half of a.

Isotopes have the same number of electrons as an atom of that element. When it comes to physical properties of isotopes including mass melting or boiling point density and freezing point they are all different. Since atomic number and the element name are dependent on the number of protons those answer choices wont work.

The electric charge can be different but remember the wording of the question. Since atomic number is same so we can say that total charge of the two atoms must be same. Properties such as melting point boiling point density etc which depend upon the atomic mass should be different for different isotopes because the isotopes of an element have different masses.

How many protons does an uncharged zinc atom have. Isotopes are atoms with the same number of protons but that have a different number of neutrons. Some isotopes of elements are unstable and decay into other more stable isotopes over time.

Same atomic number in all isotopes. This also means that the isotopes have the same number of electrons. Some isotopes of elements are unstable and decay into other more stable isotopes over time.

If an atoms has the same number of protons and same number of electrons but different numbers of neurons in it then such pair of atoms as isotopes. Since the atomic number is equal to the number of protons and the atomic mass is the sum of protons. Therefore the physical properties of the isotopes must.

Lets look at Hydrogen. Must be same. The chemical properties of isotopes of a given element are almost identical as different isotopes show almost identical chemical behaviors.

Scientists in a lab are working with two different samples of the element mercury. Isotopes have same atomic numbers but different mass numbers. Isotopes of an element has similar chemical properties but different physical properties.
