Favorite Answer. protons give the identity of the element, the number of protons is the atomic number a) look on the periodic table, and look up 12, what is its name b) if an atom has less electrons than protons, what kind of ion is it? If it has 12 electrons, it can't be an element, has to be an ion. answer choices . The element that has 9 protons is fluorine. What element has 9 protons, 9 electrons, and 10 neutrons? Relevance. There will be a negative charge on the atom due to more electrons, these type of ions are called anions. The element with 9 protons and 9 electrons would be Fluorine. Do you mean 10protons and 12 neutrons. 0 0. A cation carries a positive charge and has more protons than electrons. And 8 neutrons = zero charge. For example, silicon has nine possible integer oxidation states from −4 to +4, but only -4, 0 and +4 are common oxidation states. i) what is the atomic number of the element? Kate. An isotope has 9 protons and 10 neutrons. 2 See answers taskmasters taskmasters The number that appears after the symbol of the element is the mass number. If a neutral atom has 2 protons, it must have 2 electrons. It usual ion is 'F^-' ,where it has gained one electron. The non isotope form of fluorine has 9 electrons 9 protons and 10 neutrons. Tags: Topics: Question 13 . Since it has 9 protons, it is the element Flourine. ii) what is the mass number of thr element? An isotope of the element fluorine has 9 protons and 10 neutrons. Using the number of protons, electrons and neutrons, we can identify and label the atomic or ionic species. For example every helium atom has 2 protons, but naturally it can have 1 or 2 neutrons. Number of protons in species X = 17 . If a neutral atom has 10 protons, it must have 10 electrons. Neutrons do not have a net electric charge, so the number of neutrons does not matter in the calculation. In the nucleus there are also 12 massive, neutral particles, 12 neutrons. 25. You get the idea. If it has 12 protons that means it has 12 units of positive charge and 10 electrons which means 10 units of negative charge. the atom of an element has 9 protons, 9 electrons and 10 neutrons. optionally include a subscripted 9 below the 19, to indicate number of protons. We have also distinguish between the possible and common oxidation states of every element. And 10 electrons = -10 charge. Also, usually one form is much more abundant than the other, with helium 99.999% is in the 2 neutron form. Miss. Its atomic number is 14 and its atomic mass is 28. The atom has a -1 charge because the charge on an atom is determined by the number of protons in the atom's nucleus and the number of electrons on its shell. Answer to: What is the atomic number of an element with 9 protons, 10 neutrons and 8 electrons? Lv 5. 4 5 8 9 ...” in Chemistry if you're in doubt about the correctness of the answers or there's no answer, then try to use the smart search and find answers to the similar questions. Electrons are a type of subatomic particle with a negative charge. number of nucleons (protons, neutrons combined) is 9 + 10 = 19. thus it would be referred to as "fluorine-19" and the symbol would be 19F. 3 0. Actually it's fluorine 19, F-19. 9 years ago. The non isotope form of fluorine has 9 electrons 9. Q. 2 See answers dhruvsh dhruvsh No of protons = Atomic number = 9 Atomic number = 9 Mass number = No of protons + No of neutrons = 9 + 10 Mass number = 19. sid230 sid230 A) the atomic number = no. put a) and c) together and you get its symbol . (ii) Mass number of X = 17 + 20 = 37 (iii) Atomic number of X = 17 Find an answer to your question “An element has 4 protons, 5 neutrons, and 4 electrons.What is the atomic mass of the element? put a) and b) together and you have the name c) if it has 10 electrons and 12 protons what is its charge? In your case, the atom is said to contain eight protons nine neutrons -> they do not influence the net charge of the atom ten electrons Now, electrons and protons carry opposite charges. There is no such thing. number of protons identifies the element to be fluorine (F). 13. For most of the remaining elements, there are more neutrons than protons, because extra neutrons are needed to keep the nucleus together by overcoming the mutual repulsion of the increasing numbers of protons concentrated in a very small space. An isotope of any element can be uniquely represented as \(^A_Z X\), where X is the atomic symbol of the element. Therefore, 9 protons = +9 charge. In your case, you have 8 protons and 10 electrons. The number of protons, #Z#, defines the atomic number, and the Periodic Table is arranged according to #Z#. The number of Protons determines which element it is. (6 protons makes Carbon, 8 protons makes Oxygen.) Answer and Explanation: I'm not sure if it's F-10, Ar-18, or Ar-19. number 30 on periodic table = Zn, zinc ... the number after the dash is the mass number = sum of protons and neutrons ... 30 + 34 = 64, so this is Zinc-64 - 27774288 9 protons means it is fluorine, and 10 neutrons means we write it as "_9^19F, but having 10 electrons, which is one more than the number of protons, means the ion has a negative charge, so "_9… As a result: number of neutrons = (number of neutrons+protons) - (number of protons) which is the same as: number of neutrons = mass number - proton number Using that: Fluorine (F) - 9 Protons, 10 Neutrons, 9 Electrons Carbon (C) - 6 Protons … Similarly, adding electrons results in a negative oxidation state. Atoms with 7 protons are Nitrogen. What element contains 9 protons, 9 electrons, and 10 neutrons? 4 Answers. Second orbit or L-shell will have 2n 2 = 2 x 2 2 =8 electrons. Neutrons have no electrical charge, but do add weight. 5 years ago. An atom of an element in a compound will have a positive oxidation state if it has had electrons removed. Since it has 12 protons that means its atomic number is 12 and we know the element with atomic number 12 is Magnesium (Mg). You get the element by looking at the atomic number which is the number of protons. The number of protons of an atom cannot change via any chemical reaction, so you add or subtract electrons to get the correct charge. SURVEY . 10 protons can only mean neon. Cazley. Thus, for this item, the mass number is 19. A proton is said to carry a 1+ charge, while an electron is said to carry a 1-. Since it has 10 neutrons, it is an isotope, F-10 to be exact. Electrons = 18 . Neutrons = 20 (i) The particle is called an ion because of the more number of the electrons in the atom. B an ion from a given element has 9 protons and 10.
