Your answer is A....They have the same number of protons and neutrons, but a different number of electrons. They have the same number of protons and electrons, but a different number of neutrons. Different isotopes of an element have the same atomic number, but different mass numbers.....
D. Protons Isotopes of the same element share the same amount of protons only. The number of neutrons can be determined depending on the molar mass of the element minus the number of protons. Example: Isotopes of Carbon are Carbon 12 and Carbon 14 Carbon 12 has a molar mass ( molecular weight) of 12 minus 6 protons it has will give you 6 neutrons. Carbon 14 will have (14-6) = 8 neutrons. The number of electrons will be the same in both elements as long as they remain as neutral elements
Using Gay-Lussac's Law, pressure is proportional to (absolute) temperature in Kelvin. We first convert the temperature values to Kelvin: 110 C = 383.15 K, while 65 C = 338.15 K. P1/T1 = P2/T2 22.5/383.15 = P2/338.15 P2 = 19.9 psi
Explanation: this is because the energy level of the emitted of absorbed photon increases as the number of electron shell decreases, thereby making the inner shell have higher energy than other shells
