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...
Many of the elements on the periodic table have ‘isotopes’ that have the same chemical properties with different mass numbers. The different ratios of these isotopes can be measured in many of the chemical components that make up gases, oils, contaminants, and water. Often, the isotope ratios...
If two atoms have the same number of electrons, then they would have the same electronic configuration and in turn, the same number of valence electrons. This would cause them to have the same valency also. The chemical properties of a element depend...
句子 The isotopes of a given element have the same chemical properties but slightly different physical properties. 问题 句子分析(俗称“长难句分析”)是训练提高基础阅读能力的有效手段。我们通过对托福(TOEFL)、雅思(IELTS)、GRE、考研以及四六级等考试中真实出现过的句子(如真题、TPO,剑桥系列)进行结构化分析...
• So Isotopes are atoms of the same elements with different neutron numbers correct ? • Isotopes have different mass numbers.• In my textbook it mentions that "Isotopes have different physical properties." This is basically saying that identical elements ,made up of different atoms with ...
This is due to the fact that the radioactive isotopes have the same chemical and physical properties as stable isotopes of the same element, and as they emit radiation which permit us to identify and locate them. Thus the radioactive isotopes may serve as indicators or tracers in the study ...
protium. out of these three isotopes of hydrogen, out of these three isotopes of hydrogen, only tritium is radioactive in nature which emits low-energy beta particles. as the electronic configuration of isotopes is the same, they all have similar chemical properties. but they have a difference...
6 Element X has two isotopes, X and X.Which statement about these isotopes is correct? B A They have different chemical properties because they have different numbers of neutrons. B They have the same chemical properties because they have the same number of outer shell electrons. C They have...
Isotopes are atoms of the same element that have the same number of protons (same atomic number), but different in number of neutrons in the nucleus and subsequently, different mass number. As the number of protons and therefore also the number of electrons in an isotope are the same, the...
to undergo chemical reactions to form compounds or other elements. These properties are determined by the number of electrons present in the atom. Since isotopes of an element have a different number of neutrons, but the same number of electrons, they have similar chemical properties. However, th...
