Periodic Table Flashcards
Group 1
The alkali metals
Down group 1
Bigger atoms, more reactive, Higher density, lower melting/boiling point.
Alkali metals lose an electron to form…
a 1+ ion
what type of bonding do alkali metals have?
Ionic
Alkali metals React with water to produce what?
Hydrogen gas
Group VII
The halogens
Down group VII
Less reactive, higher melting and Boiling point.
What is fluorines coloured vapour?
Yellow gas
What is chlorines coloured vapour?
Dense green gas.
What is bromines coloured gas?
Red- brown volatile liquid
What is iodines coloured vapour?
Dark grey crystalline solid or purple vapour.
What type of bonds do the halogens form?
Ionic and covalent.
What do halogens form when they react with metals?
Salts
Transition element
Good conductors, dense strong and shiny, less reactive then group 1 metal also denser, stronger then group 1 and have higher melting points with the exception of mercury.
