what is an ion?
a charged atom when it loses or gains an electrons
100
what is covalent bonding?
a bond formed when electrons are shared
100
what is metallic bonding?
a bond formed by the attraction between positively charged metal ions and the electrons around them

How do you form a positive ion?

You lose an electron

200
are the electrons free to move throuout metal in metallic bonding?
yes
300
what determines the reactivity of an atom
the number of valance electrons
300

how do u form a negative ion

you gain an electron

300

what is a molecule

A molecule is a group of two or more atoms bonded together, forming the smallest unit of a pure substance that keeps its unique chemical properties

300
How do positively charged metal ions form
When metal atoms lose electrons
300
What are metals held together by
Metallic bonds
400
what is a chemical bond
the joining of atoms to form new substances

what are the physical properties of an ionic compound

hard, and high melting points, conductive when dissolved in water


400
what are the physical properties of a covalently bonded molecule
low melting points,brittle,
400
What are the physical properties of metals
Good conductors, malleable ,ductility
400
Covalent bonds happen when electrons are shared. Ionic bonds form when electrons are...
Stolen from eachother
500
how many valance electrons are in the first ring
2
500
what type of atom is ionic bonding formed between
metals and nonmetals
500

what are some molecules formed through covalent bonding

water, sugar, carbon dioxide

500
How can metal bend without breaking
You can because when you bend a metal the electrons get out of the way because they are free to move inside the metal
