Unit 3 Intermolecular Forces
Intermolecular Forces: Are forces between molecules. Depending on its strength, they can cause the formation of three physical states: solid, liquid and gas.
1. Ion-Ion Interactions: The like charges repel each other and the opposite attract.
2. Dipole-Dipole Interactions:When partial positive and partial negative charges come together.
3. Hydrogen Bonding: The strongest Dipole-Dipole interaction that happens between hydrogen and oxygen, fluorine, …
4. Van der Waals of London Forces: When polar covalent molecules move around randomly and form a temporary

415 Words | 2 PagesCovalent bonding - Covalent bonding is when two atoms share electrons this can only occur between two non-metals. They share electrons to fill up their outer shells, this makes the atoms stable. A Covalent bond can form up to one to three Covalent bonds with non-metals depending on how much electrons they possess. They don't always share electrons

667 Words | 3 PagesMatter is made up of atoms; atoms are made of positively charged protons, neutral neutrons, and negatively charged electrons. 3. The measure of space that the molecules occupy (volume) is derived from the space in between the molecules and not the space the molecules contain themselves. 4. The motions for: • Solid- are not able to move out of their positions relative to one another, but do have small vibrational movements.
Libs 4960 Atomic Theory
526 Words | 3 PagesSomalie Prak LIBS 4960 Dr. Katie Olivant Chemistry Chemistry is a study of fundamentals of inorganic chemistry. This course is designed to provide you with basic understanding of chemistry and prepare you for more advanced chemistry courses. One concept that I learned in this course was the Atomic Theory. This theory suggests that all matter is made up of tiny indivisible particles that are called atoms. Atoms can be defined as the basic unit of a chemical element or the basic building blocks of matter that make up everyday objects such as a chair, or a table.

1264 Words | 6 PagesSolids, liquids and gases are the commonly known states of matter that consist of distinguishable physical properties. A solid has a fixed volume and shape consisting of rigid particles locked into place. Because a solid’s particles have little free space to slide past one another, solids are not easily compressible and do not flow easily. An example of a solid is a couch. A
Gatorade Vs. Water
138 Words | 1 PagesA phase of matter is a uniform with respect to both its physical and chemical properties. Matter undergoes phase transitions that change from one phase to another. A state of matter is a form that matter can take such as solids, liquids, gases, and even plasmas. There are some other states of matter that appear under extreme conditions but these are the main ones you use in your everyday lives. For example, imagine you have gatorade and water.

Pre-Ap Physical Science: The Importance Of Electrons
507 Words | 3 PagesDylan Clayton Mrs. Beckwith Pre-Ap Physical Science 9 7 December 2015 The Importance of Electrons Electrons are the negatively charged subatomic particles that revolve the center, nucleus, of an atom. They are arranged in different energy levels and they orbit around the nucleus like the Earth revolves around the Sun. Electrons are important in atoms, compounds, and chemical bonds involved in chemical reactions. These subatomic particles have importanance to the organization of elements into periods & groups, characteristics of elements in the same periods & groups, and the formation of compounds based on periodic table placement.

Notwithstanding, with a ton of Van der Waals powers interfacing between two protests, the collaboration can be exceptionally solid. 14. Polar/non polar Polar molecule- is the chemical bonding is the aftereffect of either an atoms sharing at least one external circle electrons with another molecule or a particle taking external circle electrons from the molecule with which it is holding.
Essay On Water Hydrophobicity
1964 Words | 8 Pages. SUPER HYDROPHOBICITY Soumya Ranjan Sahoo (711CH1025) NIT, Rourkela Abstract: Superhydrophobicity as a sensation has turned into an increasing focus of research and technological movement, where its key viewpoints span surface chemistry, chemical physics, and cellular biology. Hydrophobic particles have a tendency to be non-polar and, accordingly, incline toward other neutral molecule and non-polar solvents. Hydrophobic atoms in water frequently bunch together, shaping micelles.
Ionic And Covalent Compounds Lab Report
902 Words | 4 PagesProperties of Ionic and Covalent Substances Lab Report Introduction The purpose of this lab was to determine which of the following substances: wax, sugar, and salt, are an ionic compound and which are a covalent compound. In order to accurately digest the experiments results, research of definitions of each relating led to the following information: ionic compounds are positive and negatively charged ions that experience attraction to each other and pull together in a cluster of ionic bonds; they are the strongest compound, are separated in high temperatures, and can be separated by polar water molecules. A covalent compound forms when two or more nonmetal atoms share valence electrons; covalent compounds are also
