Atom X has 17 protons. How many electrons are in its valence shell (outermost energy level)? A) 10 B) 3 C) 7 D) 5 If carbon has an atomic number of 6, and a mass number of 14, how many neutrons are in the atom? The at...
An isotope is defined by their mass number, as the atomic number of the isotope is the same. Answer and Explanation:1 In an isotope, the number of protons is always equal to the number of electrons, but the number of neutrons is different. Isotope is distinguished... ...

which makes the energy of Yizi gas near the planet especially high.The farther away from the planet, the lower the energy of Yizi gas.Where the energy of Yizi gas is high, the density Yizi gas is low, that is to say, the number of Yizi per unit volume is few, as shown in Fig.2...
Mathematician: Zero raised to the zero power is one. Why? Because mathematicians said so. No really, it’s true. Let’s consider the problem of defining the function for positive integers y and x. There are a number of definitions that all gi...
Suppose that, in each trial, either electrons or protons had been added to each sphere to produce its charge. In Trial 3, which of the 2 types of particles would have been added to Sphere X, and which of the 2 types of particles would have been added to Sphere Y ? A.electrons;pro...
ATP synthesis is driven by the electrochemical potential of this proton gradient; therefore, a leaky membrane wastes energy used to initially drive the protons across the membrane and limits the efficiency of ATP production. In extreme cases, ATP synthase may even work in reverse, consuming ATP ...
Mathematician: Zero raised to the zero power is one. Why? Because mathematicians said so. No really, it’s true. Let’s consider the problem of defining the function for positive integers y and x. There are a number of definitions that all give identical results. For example, one idea is...
His model correctly depicted the atom as being composed of a central nucleus which contains the protons (positively charged) and neutrons (no charge) with the electrons (negatively charged) in circular shells surrounding the nucleus...
