Chemistry topic 3 Periodic Table

What are the electrons that are in the highest energy level called?

Another name for metalloid

The atomic radius increases down a goup because electrons are added to enery levels

Electron attraction to the nucleus depends on

Are alkaline earth metals more or less reactive than alkali metals?

True or False: Cations are always larger than the metal atoms from which they are formed.

Are Cl^- and K⁺ isoelectronic?

Which of the following properties increase from Na to Ar?

The ____________ exist as single individual atoms with extremely weak forces of attraction.

The melting point of halogens ___________ down the group.

Electronegativity _____________ down a group

What is used to test for presence of halide ions?

In group 1 the reactivity ____________ down the group.

In group 17 the Van der Waals' forces between diatomic molecules __________ down the group

Sometimes called rare gases or inert gases

In group 1 the melting point

For both cations and anions the radii __________ down a group

This group is called "alkali metals" because all react with water to form a base and hydrogen.

Are the metal oxides on the left side of the periodic table ionic?

Elements with the same outer shell; horizontal rows of elements

Are Na⁺ and Be²⁺ isoelectronic?

Elements with the same number of valence electrons and therefore similar properties

These metals have variable valency & oxidation state

Which group has a general configuration of ns²?

Which atom has the highest electronegativity?

A good reducing agent can readily _________ an electron

Anions radii are always _____________ than the nonmetal atoms from which they are formed.

This group reacts by losing one outer electron to form the metal ion.

Melting point depends on ....

The energy to remove one outer electron from a gaseous atom.

True or False: Anions are always larger than the nonmetal atoms from which they are formed
