Chapter 2, Problem 5MIC

Chlorine is an element with the symbol Cl. Draw and label atomic structure of chlorine indicating the number and locations of protons, neutrons and electrons in one atom of chlorine.

Oxygen has 8 protons, 8 neutrons, and 8 electrons. What is its atomic mass?(a) 8 (b) 16 (c) 24 (d) 32.

for the first 10 atoms from the periodic table determine: the atom full name and chemical symbol atomic number atomic mass how many protons, Neutrons and electrons? Abundance in nature

The atomic mass number of an atom is determined by the sum of the number of in the atom. (a) protons plus electrons plus neutrons (b) protons plus electrons (c) neutrons plus electrons (d) neutrons plus protons

Consider iron (Fe), hydrogen gas (H2), and ammonia (NH3).Which of them is or are atoms? Which of them is or are molecules? Which of them is or are compounds? Explain eachanswer

An ion has 15 protons, 16 neutrons, and 18 electrons. The symbol for the ion is 31P3+. 31P3-. 31Ar3+. 34S+. 34S-.

How many electrons does a neutral Chlorine (Cl) atom have in its outermost electron shell?

Use your copy of the periodic table to answer this question: If you add an electron to fluorine, what will result? A) a negatively charged anion B) a different atomic number C) a different isotope D) a different element E) a positively charged cation

The “octet rule” in chemistry helps predict the types of bonds thatatoms will form. In general, an atom will be most stable if it fills itsouter shell of 8 electrons. Atoms with fewer than 4 valence electronstend to donate electrons and those with more than 4 valence electronstend to accept additional electrons; those with exactly 4 can do both.Using this rule, determine what category each of the followingelements falls into: N, S, C, P, O, H, Ca, Fe, and Mg. (You will needto work out the valence of the atoms.)
