Protons = 10; electrons = 10. Chapter 2 Section … WebTherefore, a nitrogen atom has seven protons and seven electrons. The number of neutrons in an atom can be determined by the difference between the atomic mass and the number of protons. The difference between the mass number of the nitrogen atom and the number of protons is seven. Therefore, a nitrogen atom has seven neutrons.

Webproton, stable subatomic particle that has a positive charge equal in magnitude to a unit of electron charge and a rest mass of 1.67262 × 10−27 kg, which is 1,836 times the mass of an electron. Protons, together with electrically neutral particles called neutrons, make up all atomic nuclei except for the hydrogen nucleus (which consists of a single proton). Every … WebAt a certain pressure the density of the liquid is 0.466 g/cm 3. What is the mass of a 15 mL sample of this liquid CO 2? Answer Note: 1 cm 3 = 1 mL ( 15 mL CO 2 ) ( 0.466 g CO 2 1 mL CO 2 ) = 6.99 g CO 2 A student was given the task of determining if the pure metal she had was nickel (d = 8.90 g/mL) or zinc (d = 7.14 g/mL). WebNumber of gram atoms will be 0.5×2N A=N A ( Since one molecule of oxygen contains 2 atoms of oxygen) 1 mol of a gas occupies 22.4l at STP, thus given sample will occupy 11.2l at STP.
