Metals.
But I'd rather you learnt more from my answer so hear me out. Get your Periodic Table and lay it out in front of you. Find Boron (B), it's on the right hand side, on the left of the sticky up bit. Got it? Draw a thick pencil mark underneath it. Now go down in a zig zag pattern drawing a line between Aluminium (Al) and Silicon (Si), underneath Silicon and down between Germanium (Ge) and Arsenic (As) etc.
Done it? All the elements on the left hand side of that line are metals. All the elements on the right hand side are non-metals. There are way more metallic elements than non-metallic ones. It's only because compounds are non-metallic that we have so many non-metals in our world.
A word of caution. Some periodic tables put Hydrogen (H) at the top of the first column. Others have it floating above the whole table, completely separate. That's because Hydrogen is an odd one out. Technically it belongs in the first column; it's reactive, it's unstable, it has just one outer electron. However, it's not a metal. So it doesn't really fit there. Hence the 'floating' versions of the table. If you remember the zig zag and that H is the odd one out you'll be ok.
All you have to do is look on your periodic table of elements. Metals are to the left and non-metals are to the right. This way we know group four are metals.
The nonmetals in Group 7A are called halogens. They include elements such as fluorine, chlorine, bromine, iodine, and astatine. Halogens are highly reactive elements that tend to form salts when they react with metals.
The halogens (Group 17) are the most reactive non-metals in the periodic table. They have seven valence electrons and readily gain an electron to achieve a full outer shell, resulting in high reactivity. This group includes elements such as fluorine, chlorine, bromine, and iodine.
Francium is in the period 7 and group 1 of the periodic table (alkali metals).
The more common name for group 7 metals is the halogens. This group includes elements such as fluorine, chlorine, bromine, iodine, and astatine. Halogens are highly reactive nonmetals that readily form salts with metals.
non-metal
Group 18 of the Periodic Table has only non metals. Additionally, the stable elements of group 17 are also non metals.
Chlorine is a non-metal. It is found in group 7 of the Periodic Table of elements and has electronic configuration [Ne] 3s2 3p5.
it describes what are metals, non-metals and what are metalloids (semi-metals) group 1: Alkali Metals (reactive) group 2: Alkaline earth metals (reactive) group 3-12: transition metals group 13-17: non metals group 17: non metal, BUT ALSO a halogen group 18: Noble gases (inert - non reactive) Hope i helped you out, :) Alana
Group 1 (for metals) and group 17 (for non metals).
Group 1-12 (all metals). Group 13-16 contains metals, metalloids as well as non-metals.
Group 7 elements, also known as the halogens, are all nonmetals. They include fluorine, chlorine, bromine, iodine, and astatine. They are highly reactive and have seven electrons in their outer shell, making them strong oxidizing agents.
it is group 14.(non-metals)
Group 1 (for metals) and group 17 (for non metals).
Noble gases (group 8 or 0), Metals (left of the zig-zag line)and non-metals(right of the zig-zag line), Halogens (group 7), Transition metals ( metals that are not in groups/ in the middle)
Group-17 are most reactive non-metals. They form halogens.
All you have to do is look on your periodic table of elements. Metals are to the left and non-metals are to the right. This way we know group four are metals.
