Answer The number of protons in the element of atomic number 16 is 16. Explanation Given information: The atomic number of sulphur is 16. The positively charged subatomic particles known as protons were first found in the nucleus by Eugen Goldstein. The count of protons in the nucleus of an element's atom is known as the element's atomic number. An element is identified by its atomic number. As the atomic number of sulphur is 16, the neutral sulphur atom has 16 protons. Interpretation Introduction Interpretation : The number of electrons for the given element is to be calculated. Concept Introduction : Electrons are negatively charged subatomic particles that revolve around the nucleus discovered by J. J. Thomson. Answer The number of electrons in the element of atomic number 16 is 16. Explanation Given information : The atomic number of sulphur is 16. Electrons are negatively charged subatomic particles that revolve around the nucleus discovered by J. J. Thomson. The atomic number of an element is equal to the number of electrons that revolve around the nucleus. As the atomic number of sulphur is 16, the number of electrons is also 16. Interpretation Introduction Interpretation : The atomic number for the given element is to be calculated. Concept Introduction : The count of protons in the nucleus of an element's atom is known as the element's atomic number. An element is identified by its atomic number. Answer The atomic number for the element is 23. Explanation Given information : The number of protons is 23. The count of protons in the nucleus of an element's atom is known as the element's atomic number. An element is identified by its atomic number. As the number of protons is 23, the atomic number will also be 23. Interpretation Introduction Interpretation : The number of electrons for the given element is to be calculated. Concept Introduction : Electrons are negatively charged subatomic particles that revolve around the nucleus discovered by J. J. Thomson. Answer The number of electrons for the element is 23. Explanation Given information : The number of protons is 23. Electrons are negatively charged subatomic particles that revolve around the nucleus discovered by J. J. Thomson. The number of protons is equal to the number of electrons for a particular element. Since the count of protons is 23, the number of electrons is also 23. Interpretation Introduction Interpretation : The given element is to be calculated. Concept Introduction : The count of protons in the nucleus of an element's atom is known as the element's atomic number. Answer The element with atomic number 5 is boron and its symbol is B. Explanation Given information : The number of electrons is 5. The count of protons in the nucleus of an element's atom is known as the element's atomic number. The number of electrons is equal to the element’s atomic number. The element with atomic number 5 is Boron. The symbol of boron is B. Interpretation Introduction Interpretation : The atomic number for the given element is to be calculated. Concept Introduction : The count of protons in the nucleus of an element's atom is known as the element's atomic number. Answer The atomic number of the element is 5. Explanation Given information : The number of electrons is 5. The number of protons in the nucleus of an element's atom is known as the element's atomic number. The number of electrons is equal to the element’s atomic number. So, the atomic number of the element is 5.
