What is the same about physical and chemical properties?
A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. A chemical property describes the ability of a substance to undergo a specific chemical change. To identify a chemical property, we look for a chemical change.
Which two elements will have similar physical and chemical properties?
Explain your answer. Sodium and potassium share similar physical and chemical properties because they are in the same family or group called Alkali metals.
Why do all the elements in group 16 share similar properties answers com?
All elements in group 16 share similar properties because their valence shells all contain the s2p4 electron configuration.
Why are halogens kept in group 17 of modern?
The halogens are located on the left of the noble gases on the periodic table. Because the halogen elements have seven valence electrons, they only require one additional electron to form a full octet. This characteristic makes them more reactive than other non-metal groups.
Why are Group 17 elements are called halogens?
The elements of Group VIIA (new Group 17 – fluorine, chlorine, bromine, iodine, and astatine) are called the halogens (tan column). The term “halogen” means “salt-former” because these elements will readily react with alkali metal and alkaline earth metals to form halide salts.
Is Group 17 soluble in water?
Physical state: The group 17 elements are found in diverse physical states. For example, Fluorine and Chlorine are gases. Solubility: Florine and Chlorine are soluble in water. On the other hand, Bromine and Iodine are very less soluble in water.
What do all the elements in group 17 have in common?
As you can see in the periodic table below, the halogens include the elements fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). All of them are relatively common on Earth except for astatine. Therefore, halogens have seven valence electrons.
What element in Group 17 is a liquid?
Bromine
What family in the periodic table does hydrogen belong to?
Alkali Metals
