The structure of an atom is very different from when atoms bond.
The structure of an atom, is basically the arrangement of the subatomic particles forming the atom. This includes the nucleus, made of protons and neutrons, and the electrons circling the nucleus.
When atoms bond together, it is when valence electrons are either taken from another atom or given to another atom to form a bond. Water, for example is a bond. It contains hydrogen and oxygen bonded together. This is where we get H2O. There are two atoms of hydrogen and one atom of oxygen to make the water molecule.
What else can I help you with?
Can the surface tension of water be made stronger?
Yes, the surface tension of water can be increased by adding certain substances such as surfactants or ions. These substances can alter the surface properties of water molecules, making the surface tension stronger.
Can matter undergo changes in both its physical and its chemical properties?
Yes, matter can undergo changes in both its physical and chemical properties. Physical properties changes do not alter the composition of the substance, such as changing state from solid to liquid. Chemical properties changes involve a chemical reaction that results in the formation of new substances with different chemical compositions.
Why is folding paper a physical change?
Folding a paper does not form new substances.
Why is the creation of a mixture considered a physical change not a chemical change?
Creating a mixture involves physically combining two or more substances without changing the chemical makeup of the individual substances. A chemical change, on the other hand, involves a rearrangement of atoms and the formation of new substances with different properties. Mixing substances together does not alter the chemical composition of the individual components, so it is classified as a physical change.
What is the name of the study of changes to materials caused by light?
The study of changes to materials caused by light is known as photodegradation or photochemistry. This field explores how light can alter the properties and structure of materials over time.
How does the presence of hydrogen fluoride affect hydrogen bonding in a chemical compound?
The presence of hydrogen fluoride can disrupt hydrogen bonding in a chemical compound by forming stronger hydrogen bonds with other molecules, thereby competing with the original hydrogen bonds. This can weaken or alter the overall structure and properties of the compound.
How does nitric acid oxidizing affect the chemical properties of substances?
Nitric acid oxidizing can change the chemical properties of substances by adding oxygen atoms to them, which can alter their reactivity, solubility, and color. This process can also lead to the formation of new compounds with different properties.
What substance when mixed together maintain their original physical properties?
When mixing substances that maintain their original properties, look for solutions or mixtures where the individual substances do not chemically react with each other. For example, mixing salt and sugar together will not alter the physical properties of each substance.
How would changing the proportions of substances in an alloy change its properties?
Changing the proportions of substances in an alloy will change the physical properties of that alloy. The differing substances will change the metallic structure of the crystals of the metal alloy, and this alters the ductility, durability, hardness, tensile strength, toughness and other characteristics we assess are regards alloys.
Can physical properties change?
Yes, physical properties can change due to various factors such as temperature, pressure, or exposure to other substances. These changes can alter properties like color, density, state of matter, and conductivity.
How do you relate human behavior to chemical properties?
Human behavior can be influenced by the chemical properties of substances that interact with the body, such as neurotransmitters in the brain. For example, changes in the levels of neurotransmitters like serotonin or dopamine can affect mood and behavior. Understanding the chemical properties of substances can provide insight into how they might alter human behavior.
A functional group changes the structure of a compound but does not alter its chemical properties?
A functional group is a specific grouping of atoms within a molecule that determines its chemical reactivity and properties. While the addition of a functional group can change the structure of a compound, it does not necessarily alter its overall chemical properties, as the functional group will largely dictate how the compound will react chemically.
Can the surface tension of water be made stronger?
Yes, the surface tension of water can be increased by adding certain substances such as surfactants or ions. These substances can alter the surface properties of water molecules, making the surface tension stronger.
What does mean alter sentence structure?
means to change the structure of sentence
What are controlled substances?
CONTROLLED SUBSTANCES are man made drugs that cause us to alter brain activity.
What are the homophone for the word alter?
Alter - To change something. Altar - An elevated structure or place where religious rites are performed.
Can matter undergo changes in both its physical and its chemical properties?
Yes, matter can undergo changes in both its physical and chemical properties. Physical properties changes do not alter the composition of the substance, such as changing state from solid to liquid. Chemical properties changes involve a chemical reaction that results in the formation of new substances with different chemical compositions.
