Periodic Table and Trends

The elements in which additional electrons are added to the shell just below the valence shell are called

Na⁺¹ is larger than its atom

P^-3 is larger than Mg⁺²

Modern periodic law now has the PTE organized by

Transition elements have similar behavior because

When Mendeleev was organizing the periodic table, he used an element's

The second ionization energy of any element is always higher than its first ionization energy

Al⁺³ is smaller than Na⁺¹

Ionization energy is lowest for the atoms of which kind of elements?

Which is a transition element?

The elements in the lanthanide series show major differences in the number of the electrons in the

Elements with high first ionization energies tend to form negative ions

The second ionization energy of Mg is much greater than the second ionization energy of Na.

Which of the following has the most nonmetallic character?

In a series of the periodic table, the first ionization energy of an element generally increases with its atomic number

The activity of nonmetals(reactivity) increases as we move from left to right across a period

Gold, Silver, Copper, and Iron are all

Calcium will have similar properties to:

The element most similar to P will be

What happens to atomic radius as you move across the period (L to R)that starts with Sodium

The element most likely to behave as a metalloid is

Which of these elements is most reactive?

The element least likely to form a compound is

The activity(reactivity) of metals decreases as we move from left to right in a period

The activity (reacativity) of metals increases as down a family

The activity of nonmetals(reactivity) increases as we move down a family
