What element has the atomic number 01? Which element is a noble gas with 18 protons in the nucleus? What is the element based on its electron configuration (shown below)? 1s2 2s2 2p6 3s2 3p5 An atom of an element has the following groundstate configuration: (Kr)4d^105s^25p^b. a...
With this, it is easier to monitor the changes in the number of protons and neutrons when a nucleus undergoes a nuclear reaction.Answer and Explanation: The mass number of an element is the sum of the number of protons and the number of neutrons. The mass number of an ele...
The mass number represents the number of protons plus neutrons in the nucleus of an atom of the element. The number of protons determines the element, but the number of neutrons in the atom of any one element can vary. Each variation is an isotope. The isotopes with the longest half ...
positively- or negatively-charged version of the same atom. A neutrally-charged atom will have the same amount of electrons as protons. Electrons exists in orbitals, which surround the nucleus of the atoms, and it is in these orbitals that electrons can bond with other atoms to form ...
Paint 14 balls each with the colors you have selected. Each color represents protons, neutrons, and electrons of the atom. The silicone atom is the represented by atomic number 14, which is how many protons are present in the nucleus. There are the same number of electrons as protons in ...
High-energy protons interact with the nucleus of an atom in the same way as neutrons would (via strong interaction). Low-energy protons behave differently and have a much higher probability of interacting with electrons (via Coulomb interaction). Proton beams may, however, produce less accurate ...
A chemical element is a pure chemical substance consisting of one type of atom distinguished by its atomic number, which is the number of protons in its nucleus. The term is also used to refer to a pure chemical substance composed of atoms with the same number of protons.[1] Common exampl...
The number written to the right of the element's name is the mass number. The mass number represents the number of protons plus neutrons in the nucleus of an atom of the element. The number of protons determines the element, but the Did an asteroid—which contains iridium—kill off ...
What is the positively charged particle found in the nucleus? A particular atom contains 29 electrons, 34 neutrons, and 29 protons. Which element is this and tell its atomic number? Write the symbol for the nuclide with 47 protons and 61 neutrons and identify the element. ...
