https://padlet.com/vyktoriacarmack/Familyproperties2 Work with your groups to determine what the chemical and physical properties of your assigned chemical family. Then write a post with the properties that you found, and add a fun video that shows off one of its properties. Be sure to write your name and the names of your group mates in the post and add the link to the information your found. en-us 2020-10-26 04:59:17 UTC 2020-10-27 16:05:16 UTC hello@padlet.com https://padlet.com/vyktoriacarmack/Familyproperties2/wish/866251738 they all have 2 valence electrons .

This reactivity is due to high electronegativity and high effective nuclear charge. Halogens can gain an electron by reacting with atoms of other elements. Fluorine is one of the most reactive elements.]]> 2020-10-27 15:45:50 UTC https://padlet.com/vyktoriacarmack/Familyproperties2/wish/866262469 https://padlet.com/vyktoriacarmack/Familyproperties2/wish/866264564 They are reactive with air and water and they are shiny, soft, silvery. alkali metals must be stored under oil to prevent reaction with air]]> 2020-10-27 15:46:15 UTC https://padlet.com/vyktoriacarmack/Familyproperties2/wish/866264564 s5099834 https://padlet.com/vyktoriacarmack/Familyproperties2/wish/866264994 Halogens are nonmetals in group 17  of the periodic table. Down the group, atom size increases.Due to their high effective nuclear charge, halogens are highly electronegative.fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At) Are the elements.We use the element chlorine to purify water when we go swimming.]]> 2020-10-27 15:46:20 UTC https://padlet.com/vyktoriacarmack/Familyproperties2/wish/866264994 s5295602 https://padlet.com/vyktoriacarmack/Familyproperties2/wish/866278315 Alkaline earth metals tend to be shiny and silvery white. They are somewhat reactive at standard temperature and pressure. They have low densities, melting points, and boiling points.
