6 Rubidium has two isotopes, Rb and Rb.Which statement explains why both isotopes have the same chemical properties? B A They have the same number of protons. B They have the same number of outer shell electrons. C They have different numbers of neutrons. D They have different mass numbers...
The isotopes of a given element have the same chemical properties but slightly different physical properties. We now know that atomic number (the number of protons in the nucleus), not atomic mass number (the number of protons and neutrons), determines chemical behavior.Mendeleyev went further ...
The number of protons in the nucleus of an atom determines what element it is, sothe number of protons is fixed. But, the number of neutrons can vary. Nuclei with the same number of protons but different numbers of neutrons are called isotopes. ... Chemical properties in general do not ...
The image shown above depicts how additional neutrons create different isotopes of hydrogen. Isotopes have the same number of electrons, and therefore have the same chemical properties. There is, however, a difference in the element’s physical properties due to their difference in mass (number of...
What properties do you expect it to have?Elements in the same group in the periodic table (a) have similar chemical properties. (b) are called isotopes. (c) have consecutive atomic numbers. (d) make up a period of elements.What are the e...
As you may know, atomic elements can have different isotopes, which are different versions of an element that have the same number of protons, but different numbers of neutrons contained within the nucleus. Thus, the atomic mass of these isotopes will be different, as will some of their phys...
A god doesn’t control them; the physical properties of matter and energy control the universe. This principle is at the center of naturalism — the idea that only matter and energy exist, and they have properties that are repeatable, understandable, and quantifiable within the limits of ...
Metaculus has 2 but not 1. I wouldn’t be surprised if it gets good answers to the things it’s asking, but it’s never going to be the same kind of fun tool for little real-life questions that PredictionBook is, and it probably doesn’t have the same potential to encourage communi...
The periodic table is a graphical layout that not only gives information about individual elements, but also elements that have similar properties. The seven rows in the periodic table are known as thePeriods. Each element in a particular row has the same number of electron shells surrounding the...
While centrifugation is the best option for simulating high gravity, there are other techniques that may be used to separate materials. These includefiltration, sieving, distillation,decantation, andchromatography. The best technique for an application depends on the properties of the sample being used...
