PPT-5.2 Nuclear Reactions

In the nuclear equation for alpha decay the mass number of the new nucleus decreases by 4 and its atomic number decreases by 2 Learning Goal Write a balanced nuclear equation showing mass numbers and atomic numbers for radioactive decay. Atoms consist of a nucleus surrounded by electrons. Chemistry is produced by interactions involving the electrons around the atom. t. his involves small energy changes (~0.01 eV) and can happen at room temperatures. ________________ involve changes in atomic nuclei. . Spontaneously-changing nuclei emit ________ and. are said to be _________. . Chemical reactions. Nuclear reactions. radiation. radioactive. energy and/or particles. Synthesis reactions. Decomposition reactions. Single replacement reactions. Double replacement reactions. (Precipitate reaction). Chemical Reactions can be written as:. Word equation. Chemical equation.

Females . are . 1.3-1.5 . times more likely to develop drug eruptions, except in children under the age of 3 where boys are more likely to be affected. . How do stars work and evolve?. Why do stars shine?. Nuclear reactions. Fusion and fission reactions. How nuclear reactions can create energy. Why is it hard to get fusion nuclear reactions to occur?. Our estimates of pressures and temperatures experienced by rocks during metamorphism are based on metamorphic reactions.. Mineral Reactions. There are two basic types of mineral reactions:. Continuous. These are the OPPOSITE of neutralization reactions (i.e. acid-base reactions). Rather than forming a salt and water from an A-B reaction, a salt and water react to form an acid and a base.. You MUST determine if you have a Strong or Weak Acid and a Strong or Weak Base..
