Chemistry Reactivity test

What are metals’ characteristics?

Good conductor, malleable, ductile, high boiling and melting point, shiny, and solid at room temperature

What are nonmetals’ characteristics?

Poor conductor, brittle, low melting and boiling point, dull, and liquid or gas at room temperature

What are metalloids’ characteristics?

Semiconductor, brittle, either a low or high boiling/melting point, shiny, and solid at room temperature

Does metals reactivity increase going right or left and why

They increase going left because they would have less and less electrons to giveaway

Does metals’ reactivity increase going up or down and why?

Increases going down because the atomic radius is bigger

Is it easier or harder to take an electron from a large atom? Are they more or less reactive?

It is easier to take an electron from a larger atom so they are more reactive

Do nonmetals’ reactivity increase going left or right and why?

Going right because the elements gain protons going right so their attraction to electrons increases

Does nonmentals’ reactivity increase going up or down and why?

Going up because they become smaller and smaller atoms are more strongly attracted to electrons

What are groups?

Families/columns

What are periods?

Rows

How can you tell the energy levels of an element?

The row number

Are noble gases inert? What does inert mean?

Yes, inert means unreactive

What is ionization energy?

Energy needed to take an electron

What is electronegativity?

Atom’s attraction to electrons/strength to keep them

Which elements are liquid at room temp? What are their groups?

Br/Bromine is a nonmetal and Hg/Mercury is a transition metal
