Oxygen and Carbon will:
A. Ionically bond
B. Covalently bond
B. Covalently bond
Magnesium and Flourine will:
A. Ionically bond
B. Covalently bond
Ionically bond
This type of bond involves the transfer of a valence electron
Ionic bond
Which element is most similar in behavior to
calcium (Ca)?
Magnesium
This type of bond involves two atoms sticking together
Covalent bond
How does the atomic radius change as you move left to right in Period 3 from aluminum through chlorine?
It decreases
How are all of the atoms in group 3 similar?
They all have three valence electrons in their outer shell
Which two groups are the most reactive?
Halogens and alkali metals
Which statement is the best reason why the atomic radius generally increases going down group/family of elements?
The number of shells increases
The greater the number of valence electrons…
The more attraction they have with the atomic nucleus
Each time you go down a period in the same family…
A valence electron is added
