D block elements are also known as
transition metals
Which block are alkali metals found?
s block
Which block are alkali earth metals found?
s block
Alkali metals are named because they form alkaline solutions when reacting with
water
Quantum Mechanics model describes what about the electrons?
The likely shapes where the electrons will be found
Why are group 1 elements usually naturally found as compounds?
They are very reactive so react with other atoms in nature
What are metalloids?
Atoms that demonstrate properties of both metals and non-metals
Halogens are called this because it means
"salt forming"
Radon is in what family?
Noble gases
Why do transition metals have different ionic charges?
They have varying electron cloud shapes, so interact in multiple ways
Which group is the most electropostive?
1
Which group is the most electronegative
17
Which element is the most electronegative in the periodic table
fluorine
Atomic size depends on:
The period an element is found, and how many energy shells it has
Define 'core charge'
The amount of positive pulling force the nucleus has on electrons
Define ionisation energy
The amount of energy required to remove a valence electron
