1. explain what happens to an atom when the number of protons, neutrons, or electrons changes, while the number of the other two particles remains the same. 2. Are there different ways to make an oxygen atom?

Which of the following statements is false?a. Atoms of the same element that have different masses are called isotopesb. The masses of isotopes vary because they have a different number ofelectronsc. The mass number of an isotope is the total number of protons and neutronsin the nucleusd. The mass number of an isotope is the total number of protons and neutrons,but without being given the number of electrons.e. Every atom of a particular element has the same number of protons

Which statement is true? O a. Protons and neutrons have the same mass, but electrons are much lighter. All three particles are evenly distributed throughout the atom. Protons are positively charged, neutrons are neutral, and electrons are negatively charged. O b. Protons and neutrons have the same mass, but electrons are much lighter. Protons and neutrons are in the nucleus, and electrons occupy energy levels in the electron cloud. Protons are positively charged, neutrons are negatively charged, and electrons are neutral. OC. Protons, neutrons, and electrons have equal mass and are evenly distributed throughout the atom. Protons are positively charged, neutrons are neutral, and electrons are negatively charged. O d. Protons and neutrons have the same mass, but electrons are much lighter. Protons and neutrons are in the nucleus, and electrons occupy energy levels in the electron cloud. Protons are positively charged, neutrons are neutral, and electrons are negatively charged.

Which of the following statements is TRUE, and why? A. Anions are usually larger than their corresponding atoms.  B. A neutral atom contains the same number of protons and neutrons. C. Protons and electrons contribute equally to the mass of the atom.

If an element is composed of atoms with an atomic number of 8 and a mass number of 14, then an electrically neutral atom of this element contains     A) 6 protons.     B) 6 neutrons.     C) 6 electrons.     D) 14 protons.     E) 14 electrons.

Which of the following statements are true concerning the core charge of carbon-12, carbon-13, and carbon-14. a. The core charge would change because the number of neutrons are changed in these isotopes of carbon b. The core charge would remain the same since the number of protons changed with the number of electrons c. The core charge would be 12, 13, and 14 respectively for these isotopes of carbon d. The core charge can never change for any element, since the number of protons and number of core electrons are constant for any element
