Сhemical bond can be classified in four groups:

Сhemical bond

↙ ↘

ions metallic Covalent hydrogen bond

Т: What is a compound?

S: The compounds consist of two or more elements

Т: What compounds are ionic compounds?

S: ionic compounds are the real metals and the actual nonmetallic compounds

Т: What compounds are сovalent compounds?

S: The compound made from two nonmetallic covals is called covalent

Т: What is the covalent polar bond?

S: is a covalently bonded bond between the various atoms of the electronegativity

Writing to the stickers his wishes and putting them in the "basket of ideas." The teacher evaluates the work of the class. The best answers determine.
