Description

The element with the atomic symbol of O
Oxygen's atomic number
The meaning of the Greek word "oxygenes" which is where oxygen got it's name from
The atomic mass of oxygen
There are 11 of these, 3 of which are stable including O-16, O-17, and O-18. The most common is O-16 which has a relative abundance of 99.757%
Oxygen is all around and make up 21% of Earth's ______________
The substance that Joseph Priestly heated up to first isolate oxygen in 1774
The name that Joseph Priestly gave to the gas which he found could cause a flame to burn and keep a mouse alive and thriving
The name of the French chemist who later named the element oxygen
Colorless, odorless, and a gas are some of these properties of oxygen
Highly reactive, non-metal, high electronegativity and a strong oxidizing agent are some of these properties of oxygen
Oxygen is a non-metal with an ionic charge of -2 that _________ electrons
Oxygen is less of this compared to the elements to its left and below, but more of this compared to the elements to its right and above (this is because metals lose electrons and electrons are more easily lost going to the left and down the periodic table)
Oxygen has a smaller one compared to the elements to its left and below, but a larger one compared to the elements to its right and above (this is because to the left and down the periodic table nuclear attraction on the outer electrons decreases due to the number of protons and an increase in shells)
This is lower in elements going down and to the left of oxygen, but higher in the elements going to the right and above (this is because it is easier to gain electrons with a fuller valence shell and also when the atomic radius is smaller)
This is lower in elements going down and to the left of oxygen, but higher in the elements going to the right and above (this is because elements further to the right have nearly filled valence shells and elements near the top have a smaller atomic radius and therefore an increased nuclear attraction, all of which makes it harder to take electrons away)
The action that humans and animals take to use oxygen in order to stay alive. Other common uses of oxygen include sustaining a flame, steel production, sewage treatment and water-purification
Oxygen is the third most abundant element in the _______________
Oxygen can turn into this state at -183℃
Solid and liquid oxygen are this color
Each succeeding ionization energy is _____________ than the preceding energy because the positive charge increases with each electron taken away and the nuclear attraction on the electrons increases. Oxygen's ionization energies are as follows: 1-1313.94 kJ/mol, 2-3388.67 kJ/mol, 3-5300.47 kJ/mol, 4-7469.27 kJ/mol, 5-10989.6 kJ/mol, 6-13326.4 kJ/mol, 7-71334.2 kJ/mol, 8-84078.3 kJ/mol
