ductile, malleable, and lustrous

The modern periodic table arranges elements according to

The development of the periodic table came as a result of

Elements in Group 2 are called ___________________

Alkaline-earth metals are slightly more reactive than alkali metals

led to reorganizing the periodic table on the basis of atomic number

include almost 80% of the elements

The symbols that represent each element must always use two letters

Developed the law of octaves through arranging elements by atomic mass

Where are nonmetals found on the periodic table

Which of the following correctly arranges the elements from greatest electronegativity to least

Uranium, found below the main body of the periodic table, is best classified as a(n)

Brittle solids with metallic luster

organized elements with similar characteristics in columns like the modern periodic table

semiconductors

Elements with more protons + electrons almost always have larger atomic radii that those with fewer protons + electrons

Electron dot notation uses dots to represent all the non-valence electrons

Most transition elements have one or two valence electrons

Refer to the periodic table, What is the name for the group containing chlorine

Used letters to represent each element and superscripts to represent the number of atoms
