|---|---|---|---|---|---|
| Studied in the field of chemistry, made of particles called atoms, has mass and volume | Matter
🗑
|
||||
| These are on the periodic table and have one type of atom | elements
🗑
|
||||
| What subatomic particles are equal in atoms to make the atom neutral | protons and electrons
🗑
|
||||
| subatomic particle that is used to identify an atom.. how they are listed on the periodic table( the atomic number... is the number of ...) | protons
🗑
|
||||
| part of atom that is involved in bonding... | electron
🗑
|
||||
| forces that hold atoms together... caused by atoms sharing electrons or transferring electrons from one atom to another... | chemical bonds
🗑
|
||||
| Most compounds in organisms are actually ? because they are made by sharing electrons | molecules
🗑
|
||||
| The charge on an electron and their location | they have a negative charge and move around the atom's nucleus in energy levels
🗑
|
||||
| two subatomic particles that are added up to form the atom's mass | the protons and neutrons located in the nucleus
🗑
|
||||
| A general term that describes what forms when two or more elements are chemically combined in a fixed ratio.. examples are water , sodium chloride, glucose or carbon dioxide | compound
🗑
|
||||
| The numbers of this subatomic particle can vary from one atom to the next... for example carbon could have 6 of these , 7 or these or 8 of these... ( the result would be slight variations in the atom's mass)... | neutron
🗑
|
||||
| give the charge and location of the following subatomic particles..electron, proton, neutron | electron... negative 1 ... in energy levels around nucleus
proton... positive 1.... in nucleus
neutron.... neutral (no charge).... in nucleus
🗑
|
||||
| What makes up the universe | matter and energy
🗑
|
||||
| H2O ( 2 should be a subscript)... is an example of a ? because it shows a substance with a fixed ratio of elements.. these are used in chemical equations | chemical formula
🗑
|
||||
| What can't be changed in balancing a chemical equation | subscripts of chemical formulas
🗑
|
||||
| What can be changed in balancing a chemical equation | the coefficients in front of a chemical formula
🗑
|
||||
| What is the term for a process that breaks chemical bonds and forms other chemical bonds to make new substances... | chemical reaction
🗑
|
||||
| what term describes the starting material for chemical reactions and the related term that describes the end products of a chemical reaction | reactants and products
🗑
|
||||
| which biological process is described by this chemical reaction glucose and oxygen react to form carbon dioxide , water, and ATP... this process if converting glucose to a form the cells can use for energy | cellular respiration
🗑
|
||||
| which biological process is described by this chemical reaction. carbon dioxide and water in the presence of light and chlorophyll produce a stored energy form called glucose and oxygen as a by-product | photosynthesis
🗑
|
||||
| How many atoms of Hydrogen and Oxygen are in the following 7H20.... ( the 2 is a subscript) | 14 Hydrogen atoms ( 7 x2)
7 Oxygen atoms ... the 7 also goes with the oxygen
🗑
|
||||
| What is used to represent yield, produces, or reacts to form in a chemical equation.... things needed for the reaction such as enzymes can also be written on this part of the equation | the arrow
🗑
|
||||
| Why do chemical equations need to be balanced so the atoms of the reactants equal the atoms of the products | there is a law that states that matter cannot be created or destroyed...
🗑
|
||||
| All of the chemical reactions in an organism such as cellular respiration or photosynthesis are described as | metabolism
🗑
|
||||
| element that is the basis for organic chemistry and is called the element of life.. it is the backbone of carbohydrates, lipids, proteins and nucleic acids | carbon
🗑
|
||||
| the top 6 elements in organisms as far and importance and very common | C,H, O, N, P, S carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur

🗑
|
||||
| element that will be important in our plasma membrane, DNA, and ATP | phosphorus
🗑
|
||||
| An element that uses latin for its symbol name and is found in blood as part of hemoglobin to help transport oxygen | iron (Fe)
🗑
