Two characterstics that lead to an element being classified as a metal. Please help!

metals are
.ductile and malleable
.shiny
.sonorous
.have high melting and boiling points
.mostly hard
.mostly dense
every metal have these qualities but there are some exceptions to
Thanks
Sure! Two characteristics that lead to an element being classified as a metal are:
1. Metallic luster: Metals exhibit a characteristic shiny or reflective surface called a metallic luster. This luster is a result of the way metals reflect light due to their free-flowing electrons.
2. Good conductivity: Metals are excellent conductors of heat and electricity. This is because metals have a large number of free or delocalized electrons that can move easily through the metal's structure, allowing the transfer of heat or electricity.
To determine if an element is a metal, you can refer to the periodic table. The periodic table categorizes elements into different groups based on their properties, including metallic and non-metallic character. Most of the elements on the left side of the periodic table, including the majority of the transition metals in the middle, are metals. However, there are a few exceptions like hydrogen, which is a non-metal despite being on the left side of the periodic table.
So, if you want to determine if a specific element is a metal, you can check its location on the periodic table and also look for the presence of metallic luster and good conductivity as mentioned earlier.
