What are the seven metals of antiquity?
The seven metals of antiquity are gold, silver, copper, iron, tin, lead, and mercury. These metals were known and used in ancient civilizations for various purposes such as tools, weapons, jewelry, and coinage.
How many electrons on their outer shell does bromine have?
Seven , outer shell electrons or valence electrons increase as you move from left to right on the periodic table not including the transition metals which vary, they start with 1 valence in the alkali earth metals , and finish with 8 valence electrons on the noble gasses (group 18)
What element has a low melting point and boiling point exists as a diatomic molecule in the gas phase has seven valence electrons and readily reacts with metals to produce a salt?
The element that fits this description is chlorine (Cl). It is a diatomic gas at room temperature with a low melting and boiling point. It has seven valence electrons and readily reacts with metals to form ionic salts.
Why are alkali metals more reactive than transition metals?
Groups 3-12 do not have individual names. Instead, all of these groups are called transition metals. The atoms of transition metals do not give away their electrons as easily as atoms of the Group 1 and Group 2 metals do. So, transition metals are less reactive than alkali metals and alkaline-earth metals are.
