1. What is an ionic bond? Typically an ionic bond occurs between one metal and one non-metal ion. One atom borrows one or more electrons from another atom. An ionic bond is a type of chemical bond that occurs when one atom loses an electron to form a positive ion and the other atom gains an electron to form a negative ion‚ which then result in attraction. 2. What is a covalent bond? A covalent bond is a bond that occurs when atoms in a molecule share a pair of electrons. For example‚ “the

Nature of Matter The states of matter are solid‚ liquid‚ and gas‚ in respective order of kinetic energy. State of Matter | Definite Volume | Definite Shape | Solid | Yes | Yes | Liquid | Yes | No | Gas | No | No | Diffusion: the process in which particles mix by colliding randomly

following questions in your own words‚ using complete sentences. Based on your observations in the lab‚ categorize each unidentified compound as ionic or covalent. Explain in one or two sentences why you categorized the compounds the way that you did. (5 points) Based on my observations in the lab I categorized Substance A and Substance C as an ionic bonds because the solids don‘t conduct electricity but when in liquid state and aqueous solutions‚ electricity was conducted.

Purpose: The purpose of this lab was to analyze the trends of the atomic radius (AR) and the first ionization energy (IE) for the first 36 elements of the periodic table. Procedure: A piece of graph paper was given out by the teacher. A periodic table that has the atomic number‚ atomic radius (AR)‚ and first ionization energy (IE) was given out by the teacher. A sheet of paper was taken out to record the elements‚ atomic number‚ atomic radius (AR)‚ and the first ionization energy (IE). To record

The pantheon is made up of two principal parts; the porch; which is a highly idealised and more greek interpretation and the circular building which is much more Roman in it’s display. The pantheon follows traditional Roman architecture designed with a portico held up by eight Corinthian columns almost 12m high. The monolithic columns shafts are made of Aswan grey granite contrasted with the white pentelic marble of the capitals.The porch is supported by these Corinthian columns and is made out

Greek and Roman both share similarities‚ but have different characteristics and use different construction types. Greek architecture used Post and- Lintel construction‚ while Roman construction dominated in arches‚ domes and vaults. Post and- Lintel construction is evident in the buildings that make up the Acropolis in Greece‚ including the Pantheon and the Temple of Hera‚ which used drums to create columns or rows of columns that used fluting and tapering to make the columns appear to perfectly

The images have a lot of similarities and differences. Some similarities are that all of the images have state abbreviations on them. The columns are representing states. There are at least five towers or statues in each image‚ standing together as a group. In all of the images‚ the towers are leaning on each other. That means that they are depending on each other. In the first image‚ one tower fell over and smoke was coming off the top. In the second one‚ the second tower had also fallen over.

very‚ very polar. It is the latter which take on some of the characteristics of an ionic bond. The ionic and covalent bonds are known to be the strongest chemical bonds. An ionic bond forms when two atoms differ so much in electronegativity that one or more electrons are actually transferred from one atom to the other. Ionic bonds generally occur between a metal and a nonmetal. Due to the existence of ionic bonds‚ elements that normally would not combine because sharing electrons is either
