7.03 Atomic Theory How many neutrons does the following isotope of Nitrogen have? 7 8 15 22 POINT VALUE: 3 points - What happens to the atomic number of an atom when the number of neutrons in the nucleus of that atom increases? It decreasesIt increasesIt remains the samePOINT VALUE: 3 points - A neutral atom of Aluminum has 14 neutrons and 13 protonsHow many electrons does this Aluminum have? 1 13 14 27 POINT VALUE: 3 points - Neutral atoms always have the same number of electrons and protons neutrons and electron protons and neutrons POINT VALUE: 3 points - Isotopes of the same element always have the same AMU number A-number Z-number POINT VALUE: 3 points - The magnitude of the charge on an electron compared to the magnitude of the charge on a proton is greater is smaller is the same POINT VALUE: 3 points
This has already been answered in great detailI thought I would be able to add the ventilationI can add that there is a temperature controlled attic fanYou set it for the temperature you want the fan to come on and it comes on and shuts off above or below the settingGood job.
First question: I'm not sure which isotope the question refers to, but Nitrogen (atomic number 7) has as its most common isotope N-14, so it would have 7 Neutrons in the nucleusNitrogen-15 (rare) has 8 neutrons in the nucleus Second question: The atomic number depends entirely on the number of protons in the nucleusIf an atom had 5 protons it would be Boron, if it had 8 protons it would be Oxygen, and so onThe number of neutrons does not change the atomic numberThird question: A neutral atom has the same number of electrons as protonsIf an atom gains or loses an electron or two, then you call it an IONSo an Aluminum atom would have 13 electronsFourth question: Neutral atoms always have the same number of Protons and ElectronsFifth question: A-number (if this means Atomic number)Sixth question: The electrical charge magnitude on electrons and protons is the sameFor examplea Hydrogen atom has one proton (+) in the nucleus and one electron around it (-)The atom is electrically neutral because the (+) and the (-) balance out each other.
