For free radical formation, the more highly substituted the carbon atom is (methyl > primary > secondary >tertiary), the less energy it will require (Wade 2010). However we will only be dealing with primary and secondary carbons in this report. One of the major effects that the chloro substituent has on the reactivity of hydrogen
Number – 19g average mass 1.7g 4) If a 4th isotope of beanium, D (green), were added to the pool, how would the average atomic mass change? Mixture of an element and a compound, changing the subscript changes of the compound. 5) Compare your average atomic mass to that group next to you. Why is the number slightly different? Would the difference be larger or smaller sizes were used?
Be sure to answer the questions for each part of the lab. Deliverables Include your responses to the exercises only from this lab in a Word document named Unit 8 Labs Submit your responses as a typed document using Arial or Times New Roman 12-point font, double-spaced. This assignment is due by the end of this class period. Unit 8 Lab 8.2: Assigning Static IP Addresses Course Objectives and Learning Outcomes Identify the major needs and major stakeholders for computer networks and network applications. Explain basic security requirements for networks.
(2) hydrogen ion contains 1 electron and 1 proton, H+ ion forms when H ion lost an electron, and therefore it’s is the same thing as a proton 6. What is the chemical formula for a hydronium ion? (1) H3O+ 7. Show the relationship between a proton and a hydronium ion. Explain why one is essentially the same as the other.

Write: “Conclusions and Questions” on the left margin. • Complete the conclusion questions in this section using COMPLETE THOUGHTS written in complete, grammatically correct, sentences. h. Write a Final Summary for the entire lab experience • Include the major concepts
For example, when a carbon-14 nuclide decays by emitting a beta particle, it becomes nitrogen-14 (which is stable). [pic]C ( [pic]N + [pic]e Therefore, unlike a chemical reaction, nuclear reactions alter the identity of the atom. Types of Radioactive Decay Alpha Decays There are several different types of radioactive decay. One frequently observed decay process involves production of an alpha (α) particle, which is a helium nucleus and assigned the [pic]α. This is the common mode of decay for heavy radioactive nuclides (those with atomic number, Z > 83).
But what about atoms that have the same number of protons and different numbers of neutrons? The number of protons determines what the atom is, and some atoms have different numbers of neutrons. These called isotopes. For example, hydrogen has three isotopes: 1 2 3 H (Hydrogen) H (Deuterium) H (Tritium) Page 1 Physics 1 1 1 Size On

Atoms are made up of three particles. They are the proton (which is the positively charged particle), electron (which is the negatively charged particle), and the neutron (which has no charge at all). Ions are just an atom that has lost or gained an electron. An atom is the most stable but only when it outer most layer is filled. Isotopes- are atoms of the same element but different number of neutrons.
An atom containing an equal number of protons and electrons is electrically neutral, otherwise it is positively or negatively charged and is known as an ion. An atom is classified according to the number of protons and neutrons in its nucleus: the number of protons determines the chemical element, and the number of neutrons determines the isotope of the element. The name atom comes from the "indivisible", "not" and "I cut", which means uncuttable, or indivisible, something that cannot be divided further. The concept of an atom as an indivisible component of matter was first proposed by early Indian and Greek philosophers. In the 18th and 19th centuries, chemists provided a physical basis for this idea by showing that certain substances could not be further broken down by chemical methods, and they applied the ancient philosophical name of atom to the chemical entity.
