Periodic Classification of Elements

Periodic Classification of Elements. -Rishi. Introduction:. There are 114 elements known at present and it is very difficult to study the properties of all these elements separately. Around the year 1800, only 30 elements were known.

In groups discuss:

In groups discuss:. How would you define a compound? Use some key vocabulary terms from the first chemistry test to help you. If H 2 O and H 2 O 2 are both compounds, how are they different? How do atoms combine to form compounds?

Why do Covalent Compounds have Low Conductivity?

Why do Covalent Compounds have Low Conductivity?. Have a wider variety of properties than ionic compounds Atoms are held together with strong covalent bonds (<0.5) Bonds do NOT break Covalent compounds are also called molecular compounds. Evidence for Intermolecular Forces.

4.2 Names and Formulas of Compounds

4.2 Names and Formulas of Compounds. Ionic compounds are made up of positive and negative ions. All of the positives and negatives organize nicely. Negative-positive attract Negative-negative and positive-positive repel Ionic compounds form from the inside-out as solid crystals
