1.) the same atomic mass? Both these factors change the energy levels so they are not the same as hydrogen. A difference in isotope behavior arises when the nuclei of certain isotopes are unstable due to an imbalance in the number of protons to neutrons in the nucleus. A.-Atoms of the same element always have the same number of electrons. Chapter 2. The atoms be of the same element, and must have the same amount of protons, but different amounts of neutrons (and thus different masses). Atoms of the same element (atoms with the same number of protons in the nucleus) may have different numbers of neutrons, and so will have different masses. They contain the same number of #"protons"#, positively charged, massive, nuclear particles.This definition allows for the existence of isotopes, whose atoms contain the same number of #"protons"# (and must do because they are isotopes of the same element), but DIFFERENT numbers of neutrons, neutrally charged, massive #"nucular particles"#. Dalton believed that all atoms of the same element have the same mass.

Upvote (11) For example, all carbon atoms have six protons, and most have six neutrons as well. 0 1. He said that compounds are formed when atoms of more than one element combine. So two atoms can't behave differently because their electrons are in different positions - all atoms of the same element/isotope have thir electrons delocalised in an identical way. So all the atoms of a given element have the same energy levels because they have the same numbers of electrons and protons. Atoms, Molecules and Ions. Colm - Right! All atoms of an element have the same atomic number. Chemical Foundations: Elements, Atoms, and Ions. For example, U-238 has 3 more neutrons than U-235, but both still have the same number of protons. )10 grams B. Don't get confused and say protons and neutrons, atoms of the same elements can have different number of neutrons but same number of protons, this is called an isotope. But, all atoms are not the same. You can have a different number of neutrons in the nucleus and still have the same number of protons. We have step-by-step solutions for your textbooks written by Bartleby experts! The electrons in an atom do not have a position because they are delocalised over the whole atom. Chris - So, in summary then, all atoms of a type - or one specific element - are the same size, but, because there are nearly a hundred and twenty different elements, there's 120 atoms of different sizes? Topics. (True / False)? (1 point) A. Answered By . Atoms, Molecules and Ions. The mass number defines the number of protons and neutrons, and that can vary for an element. But some carbon atoms have seven or eight neutrons instead of the usual six. Find an answer to your question “All atoms of an element have the same? All atoms of the same element have the same number of protons, but some may have different numbers of neutrons. The identity of an element is specified SOLELY by the number of protons, massive, positively-charge particles present in the element’s nucleus. (True / False)? Homework Help. We can temporarily localise an electron by measuring its position. Yes, all things are made of atoms, and all atoms are made of the same three basic particles - protons, neutrons, and electrons. Carbon 13 has 6 protons, 7 neutrons. The atoms in the previous question are isotopes of each other. There are different amount of neutrons in an isotope but it is the same element. The same chemical element can have a different number of neutrons and still be the same element. Atoms of the same element that have a different number of neutrons are called isotopes. The next element, Lithium, has three electrons and three protons in the nucleus so the energy levels are different again. But they have same or different mass number (like that for isotopes) .
