The Neon isotope 23Ne (element number 10 in the Periodic Table) decays into Sodium (11Na).

a) How many protons, neutrons and electrons does a neutral 23Ne atom have?

b) Write down the decay sequence including all decay products.

c) For this reaction, t1/2 = 38 seconds. If I start watching at noon, how many minutes will pass before I have less than 0.5% of the sample left?

Each element has a unique atomic number, which is listed on the periodic table above the chemical symbol for the element. The atomic number is equal to the charge on the nucleus. The atomic number also equals the number of protons in the nucleus and the number of electrons in the neutral atom of the element. For example, Fluorine (F) has the atomic number 9, which means that its atoms contain 9 protons and 9 electrons. Zinc (Zn) has the...

The location of an element in the periodic table provides a wealth of information about effective nuclear charge, size, ionization energy, and electron affinity. Using this information, it is possible to predict which elements are more likely to behave as oxidizing agents and which are more likely to behave as reducing agents. Use your knowledge of periodic trends to answer the following questions about the properties you would expect of an element that is a good reducing agent.a. Zeff :...
