The number of neutrons is calculated by subtracting the atomic number from the mass number. Atoms are electrically neutral because they possess an equal number of electrons and protons. The charge and identity of an ion with 16 protons, 18 electrons and 17 neutrons would be? Name: Chlorine: Symbol: Cl Atomic Number: 17: Atomic Mass: 35.453 atomic mass units: Number of Protons: 17: Number of Neutrons: 18: Number of Electrons: 17: Melting Point Number of protons in species X = 17 . Electrons = 18 . 9 8 5 0 . Neutrons = 20 (i) The particle is called an ion because of the more number of the electrons in the atom. 12 protons, 12 electrons 4. (i) Number of protons = 17 (ii) Number of electrons = 18 (iii) Number of neutrons = 18; Element Y consists of 11 protons and electrons and 12 neutrons. 12 protons, 10 electrons 3. However, when an atom has an unequal number of protons and electron, it has an electrical charge and they create ions. Protons and neutrons are called nucleons. 1. The atom of an element is made up of 4 protons, 5 neutrons and 4 electrons. asked Apr 23, 2019 in Class VIII Science by navnit40 ( -4,939 points) atomic structure Answer to: A chlorine atom has 17 protons, 18 neutrons, and 17 electrons. An atom, which is the fundamental unit of an element, contains an equal number of electrons and protons. So, Mass number = 17 + 18 = 35 a.m.u. It has a. How many protons and electrons are present in the mg2 + ion? 17 protons, 17 electrons, and 18 neutrons c. 18 protons, 18 electrons, and 17 neutrons d. 35 protons, 35 electrons, and 17 neutrons (Recallthat mass number is the total of protons and neutrons. Which statement about subatomic particles is true? A particle X has :-17 protons; 17 electrons; 18 neutrons. If an element z having atomic weight x exists in two isotopes of mass number (x − 1) and (x + 2) then, the percentage abundance of heavier isotopes is: View solution Calculate the average atomic mass of hydrogen using the following data : I s o t o p e 1 H 2 H p e r N a t u r a l a b u d a n c e 9 9 . Symbol of the positively charged Y is Y +. So, Atomic number of X (Z) = 17. 14 protons, 14 electrons 2. The chemical element chlorine has 17 electrons, 17 protons and 18 neutrons. In an atom number of proton and electrons are equal hence atom in electrically neutral. (ii) Mass number of X = 17 + 20 = 37 (iii) Atomic number of X = 17 science. 10 protons, 14 electrons 7. Unlike protons or neutrons, electrons have no mass. 8 17 This isotope of oxygen has 8 protons (atomic number), 8 electrons and 9 neutrons. 14 protons, 12 electrons 5. As we know electron and proton charge is equal and opposite. 0 1 5 M o l a r m a s s 1 2 Element Y will readily lose an electron to form a positively charged cation. Atomic number is the number of protons or electrons. Mass number is nothing but the sum of number of electrons or protons and number of neutrons. B. C. Neutrons have … There will be a negative charge on the atom due to more electrons, these type of ions are called anions. Chlorine has atomic number 17 and mass number 35. What is the atomic number of chlorine? 17 protons, 17 electrons, and 52 neutrons b. 10 protons, 12 electrons 6. A. Protons, neutrons, and electrons all have about the same mass.
