Question 1

The size of an atom depends on____

Answer 1

How far away the electrons (valence electrons)

Question 2

Size of an atom depends on how much ______ an electron takes up

Answer 2

Space

Question 3

When measuring an atom it’s important to state of its an _____ atom or if it’s bonded to something else

Answer 3

Isolated

Question 4

Answer 4

Measured at half the distance between 2 bonded atoms

Question 5

What is a trend?

Answer 5

Tendency to change in a predictable way

Question 6

The more you go down a group/ periodthe more _______ fill in the energy levels farther and farther away from the nucleus

Answer 6

Electrons

Question 7

The atomic radius ______ as you move down a group on the periodic table

Answer 7

Group

Question 8

As you move from left to right across the periodic table what happens?

Answer 8

You gain more protons which will hold the electrons tighter and the atomic radius will decrease

Like an ope lasso going slow motion it shrinks

Question 9

If an atom gains an a. -electron its suffix with change because that ion will be larger than its original element

Answer 9

Florine neutral vs

Floride more -

Question 10

When an atom looses an electron it will be smaller than its original atom

Answer 10

Sodium normal size vs

Sodium ion
