yes, some transition metals like gold(Au) are almost unreactive.

Does an element on the periodic table decrease in atomic size when you move across a period from left to right and when you move down a group?
1. In a period is a trend of decrease from left to right but it is not absolute.2. In a group the atomic radius increase moving down.
What happens to non metals across the periodic table?
Moving from left to right across a period, up to but not including the noble gases (group 18), reactivity increases. Moving down a group, the reactivity of the elements decreases. Fluorine is the most reactive element.
What does the land elevation do moving inland?
It may increase or decrease.
Why does reactivity of the halogens decrease down the group?
As it go down the group, the distance between the nucleus (+ve) and the last electron (-ve) becomes smaller No: BIGGER.Therefore the electrons are held in the atom very tightly more loosely by a strong weakening force from the nucleus.So, it is said as the reactivityDEcreases down the group of NON-metals which gain stronger their electrons andINcreases down the group of metals which loose those electrons.
Moving across a period on the periodic table from left to right?
ionization energy
When moving down the middle of the periodic table is there an increase in nonreactive atoms?
yes
How does the the reactivity of metals change when moving from left to right on the periodic table?
The metals on the left side of the periodic table are considered to be highly reactive to air while in room temperature. The ones on the right side are less reactive and are often used for construction.
What happens to the reactivity of elements in groups as the atomic numbers increase across a period?
they become more reactive since you are moving from left to right on the Periodic Table, the elements in group 17 are the most reactive.
What happens to reactivity of elements in groups labeled a as atomic numbers increase across a period?
they become more reactive since you are moving from left to right on the Periodic Table, the elements in group 17 are the most reactive.
What happens to the reactivity of elements in a group labeled A as atomic numbers increase across period?
they become more reactive since you are moving from left to right on the periodic table, the elements in group 17 are the most reactive.

What determines an element's reactivity?
The electrons determine the reactivity. How many valence electrons there are. It is easier to lose one electron rather than three, so an element with one valence electron will be more reactive than one with three.

When you are moving inland does the land elevation increase or decrease?
increase
When moving across a period in the periodic table?
The atomic number increases
