Atom Central
This structure represents the smallest unit of matter.
What is an atom?
A pure substance made of only one type of atom.
What is an element?
What are valence electrons?
Water is made up of these two elements.
What are Hydrogen (2) & Oxygen?
Pure water has an equal concentration of H+ and OH- ions, giving it this pH value?
What is 7?
This tiny, positive particle represents the atomic number of an element.
What is a proton?
This is how our bodies get the vitamins we need to survive.
What is our diet?
This type of chemical bond forms between two nonmetals when they share valence electrons?
What is a covalent bond?
This type of substance is "nonpolar" and considered to be water-fearing.
What is hydrophobic?
The smaller the number on the pH scale, the more acidic a substance, meaning it releases more of this type of ion.
What is Hydrogen (H+) ions?
Electrons fill in their shells in this way.
What is innermost to out?
Theses four elements are the most abundant elements found in living things.
What are Carbon, Hydrogen, Oxygen, and Nitrogen.
This type of chemical bonds forms between a metal and nonmetal and involves the transfer of electrons, resulting in a charged compound.
What is an ionic bond?
Water sticking to water is this property.
What is Cohesion?
The larger the number on the pH scale, the more basic a substance, meaning it releases more of this type of ion.
What is Hydroxide (OH-) ions?
A neutral atom has the same amount of these subatomic particles?
What are protons & electrons?
These include elements such as Calcium, Potassium, Sodium, & Chloride.
What are major minerals?
Each water molecule is bonded to another water molecule by this type of bond.
This phenomenon allows water to travel up thin tubes, such as plant roots & tall trees.
What is capillary action?
When an acid & base are mixed to neutralize each other, these substances are created?
What are salts & water?
What is valence shell?
What is Carbon?
In a double covalent bond, this many electrons are shared between atoms.
What is 4?
The larger Oxygen atom attracts Hydrogen's electron more strongly, giving each atom a partial charge and making water this type of molecule.
What is polar?
These vital blood chemicals absorb free ions to prevent a sudden shift in pH.
What are blood buffers?
