Atoms join together to form molecules. A water molecule has three atoms: two hydrogen (H) atoms and one oxygen (O) atom.
What particles make up an atom gizmo?
Part A Atoms are tiny particles of matter that are made up of three particles: protons, neutrons, and electrons. The Gizmo shows an atom with a single proton. The proton is located in the center of the atom, called the nucleus.
What substances make up iron?
Water is a pure substance, but it contains two kinds of atom: oxygen and hydrogen. Iron is an element because it is composed of one kind of atom. Atoms are tiny particles of matter that are made up of three particles: protons, neutrons, and electrons. The Element Builder Gizmo™ shows an atom with a single proton.
What particles make up an atom?
Atoms are constructed of two types of elementary particles: electrons and quarks. Electrons occupy a space that surrounds an atom's nucleus. Each electron has an electrical charge of -1. Quarks make up protons and neutrons, which, in turn, make up an atom's nucleus.
Is water a pure substance?
Water, H2O, is a pure substance, a compound made of hydrogen and oxygen. Although water is the most abundant substance on earth, it is rarely found naturally in its pure form. Most of the time, pure water has to be created. Pure water is called distilled water or deionized water.
Can water be created?
Yes, it is possible to make water. Water is made of two hydrogen atoms and one oxygen atom. The process to combine hydrogen and oxygen is very dangerous though. Hydrogen is flammable and oxygen feeds flames, so the reaction to create water often results in an explosion.
What makes a substance a substance?
A substance is a matter that has definite properties and composition. Every pure compound and element is a substance. Water, H2O, is a pure substance, a compound made of hydrogen and oxygen. Every pure substance is homogeneous. Pure substances can be divided into two categories – elements and compounds.
What are the names of the stable forms of carbon?
Pure carbon is found in three stable forms at room temperature: graphite, diamond, and the fullerene form.
How many electrons fit in the part of the third energy level shown?
Note: The third energy level can actually hold up to 18 electrons, so it is not really filled when it has 8 electrons in it. But when the third level contains 8 electrons, the next 2 electrons go into the fourth level.
How many electrons can the first energy level hold?
two electronsEnergy level I has just one orbital, so two electrons will fill this energy level. Energy level II has four orbitals, so it takes eight electrons to fill this energy level. Q: Energy level III can hold a maximum of 18 electrons.
Why do some objects float while others sink gizmo answer key?
Why do some objects float, while others sink? Some objects sink when they are denser than the liquid. What do the floating objects have in common? Have a lower mass than volume.
What are the stable isotopes of nitrogen gizmo answer key?
What are the stable isotopes of nitrogen? nitrogen-15, carbon-14, nitrogen-14.
How many valence electrons does each atom have gizmo?
Most atoms are stable with a configuration of eight valence electrons. This is known as the octet rule. How many valence electrons does each atom have? Each electron has a charge of 1-, and each proton has a charge of 1+.
How many atoms are in a hydrogen molecule h2 )?
two hydrogen atomsEach hydrogen molecule in hydrogen gas consists of two hydrogen atoms bonded together.
What are some substances that make up water?
Water, a substance composed of the chemical elements hydrogen and oxygen and existing in gaseous, liquid, and solid states.
What particles make up an atom gizmo?
Atoms are tiny particles of matter that are made up of three particles: protons, neutrons, and electrons. The Element Builder Gizmo ™ shows an atom with a single proton. The proton is located in the center of the atom, called the nucleus.
How can you calculate the number of neutrons N in an atom gizmo?
To calculate the number of neutrons in the nucleus of an atom is simple. You take the atomic, or proton number of the element, and you subtract it from the element’s mass number.
What is the Lewis structure of water?
The Lewis structure of water shows that the oxygen atom has two lone pairs. Those lone pairs, together with the large difference in electronegativity between oxygen and hydrogen, give water one of its most important properties, its strong polarity.
Why is water called water?
The word water comes from Old English wæter, from Proto-Germanic *watar (source also of Old Saxon watar, Old Frisian wetir, Dutch water, Old High German wazzar, German Wasser, vatn, Gothic (wato), from Proto-Indo-European *wod-or, suffixed form of root *wed- (” water “; “wet”).
What is the heaviest stable isotope?
Examples of elements with doubly magic nuclei are 42He, with 2 protons and 2 neutrons, and 20882Pb, with 82 protons and 126 neutrons, which is the heaviest known stable isotope of any element.
What are electrically charged particles called?
Many fundamental, or subatomic, particles of matter have the property of electric charge. For example, electrons have negative charge and protons have positive charge, but neutrons have zero charge.
Abstract
Abstract: We describe a presentation on the science of pizza, which is designed for the general public including children ages 6 and older. The presentation focuses on the science of making and digesting cheese and bread.
Introduction
This article describes a presentation we developed on the science of pizza that is geared toward nonspecialists and the general public including children ages 6 and older.
Sparking Curiosity about a Piece of Pizza
Ask any group of children (or adults) to name a favorite food, and pizza is a likely answer. Pizza's universal appeal, as well as the interesting physical properties and origins of its major ingredients, provides a rich and engaging platform for introducing scientific concepts.
Atoms to Molecules to Macromolecules to Networks
Ultimately all the major ingredients of pizza—tomatoes, cheese, and bread—come from the sun and the soil. Using energy from the sun, plants convert water and carbon dioxide into sugars and longer chained molecules of sugars, producing oxygen in the process.
The Science of Making Cheese
Cheese is central to many cultures around the world, making it an accessible food for engaging people in science. All cheese starts as milk. Studying the label of a milk container reveals that there are many components in milk, including fat, protein, and carbohydrates ( Figure 1E ).
The Science of Making Bread
Central to daily life, bread is found in different forms in cultures around the world ranging from bagels to rye bread to pizza dough. All bread products derive from flour, making the label of a bag of flour a natural starting point for a discussion of bread.
Digestion
With the knowledge of how to make cheese and bread, the next natural step is to assemble and eat pizza. Upon eating pizza, it must be digested to break down carbohydrate and protein macromolecules into smaller components, such as simple sugars and amino acids—the building blocks of food—that can be used for energy.
