What statement is true about isotopes?
ipn [44]

Answer:

D. THEY HAVE THE SAME NUMBER OF PROTONS AND ELECTRONS BUT DIFFERENT NUMBERS OF NEUTRONS.

Explanation:

Isotopy is the phenomenon that explains the various variants of an element having different number of neutrons but the same number of protons and electrons.

Isotopes are variants of a particular chemical element that possesses the same number of proton or atomic number but different mass number. The atomic number of an element is the number of protons and electrons contained by the element while the mass number is the sum total of the number of protons and neutrons in the nucleus of the elements.

Examples of isotopes are the hydrogen atom, chlorine element and so on.

Hydrogen has three isotopes which are hydrogen H, Deuterium and Tritium. Chlorine has two isotopes which are chlorine 35 and chlorine 37.

So the true options about isotopes is that they possess the same number of protons and electrons but different numbers of neutrins.

Could two objects with the same volume have different masses? Which, if either, would contain more matter?
kipiarov [429]

Answer:  Yes, two objects may have the same volume while having different masses. The object with a greater mass will be the one that contains more matter.

Explanation: Mass and volume are two different properties of matter. Mass is defined as the amount of matter that a body has. Volume is defined as the amount of space that a body occupies. Density is the property that relates mass with volume as

Density=Mass/Volume

and is defined as the amount of matter that exists in a certain amount of space.

Because mass and volume are independent from each other, we can say that two objects can have different masses and have the same volume.

<u>For example</u>, imagine two identical containers that weigh the same and that are capable of containing a volume of 1 liter each. Then, one of the containers is filled with water, while the other one is filled with mercury. In this case the volume of the water and the volume of the mercury will be the same: 1 liter, however, if we weigh the containers again, we will find that the one that has mercury is heavier than the one that has water. This is due to the density of mercury being higher than the density of water. In other words, 1 liter of mercury provides more mass than the mass provided by 1 liter of water.

Then, according to the definition of mass, the object that contains more matter will be the one that has more mass, in the case of our example, that would be the liter of mercury.

How can an electron have no net electrical charge?
solong [7]
Well not to sure if that statements true... but in hydrogen for example both its proton and electron have an electric charge but one has a + charge (proton) and the other a - charge (electron) so they end up cancelling so there is no net electrical charge 

hope that helps
