1.____________ constitutes the electrostatic attractive forces between the delocalized electrons, called conduction electrons, gathered in an electron cloud, and the positively charged metal ions. (2 Words)
5.___________is a contractive tendency of the surface of a liquid that allows it to resist an external force. (2 Words)
6.An ion or group of ions having a positive charge and characteristically moving toward the negative electrode in electrolysis
7._______________ is the most abundant compound on Earth's surface, covering about 70 percent of the planet
9.A solid is considered to be a_____________ if it has high electrical and thermal conductivity, they are malleable and ductile.
10.____________ is an attraction between atoms that allows the formation of chemical substances that contain two or more atoms (2 Words)
13.____________ is the chemical bond that involves the sharing of pairs of electrons between atoms. The stable balance of attractive and repulsive forces between atoms when they share electrons is known as covalent bonding (2 Words)
15.An ionic species having a negative charge.
16.The______________ are the substances that are formed during the chemical change. They are the things that are present at the end. By convention, the chemical symbols for the ______________ are written on the right hand side of the chemical reaction equation.
17.Water molecules stay close to each other _____________, due to the collective action of hydrogen bonds between water molecules
2.______________ occur when a substance combines with another to form a new substance, called synthesis or, alternatively, decomposes into two or more different substances. These processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. Some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. Understanding ___________________ is a major part of the science of chemistry. (2 Words)
3.In nature, _______ exists in liquid, solid, and gaseous states.
4.The atoms of ____________(adj)materials are bound tightly to each other in stable molecules, but those molecules are generally not very strongly attracted to other molecules in the material
8.____________ is a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions. Ionic bonds are formed between a cation, which is usually a metal, and an anion, which is usually a nonmetal. (2 Words)
11.The _____________ are the substances that are present before the chemical change takes place. They are the things that are present at the starting point. By convention, the chemical symbols for the ___________ are written on the left hand side of the chemical reaction equation.
12.Water also has high________ properties because of its polar nature, On extremely clean/smooth glass the water may form a thin film because the molecular forces between glass and water molecules (adhesive forces) are stronger than the cohesive forces.
14.The atoms in ___________(adj.) materials show strong attractions to other ions in their vicinity
