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

Frequently Asked Questions

What is a crossword?

Crossword puzzles have been published in newspapers and other publications since 1873. They consist of a grid of squares where the player aims to write words both horizontally and vertically.

Next to the crossword will be a series of questions or clues, which relate to the various rows or lines of boxes in the crossword. The player reads the question or clue, and tries to find a word that answers the question in the same amount of letters as there are boxes in the related crossword row or line.

Some of the words will share letters, so will need to match up with each other. The words can vary in length and complexity, as can the clues.

Who is a crossword suitable for?

The fantastic thing about crosswords is, they are completely flexible for whatever age or reading level you need. You can use many words to create a complex crossword for adults, or just a couple of words for younger children.

Crosswords can use any word you like, big or small, so there are literally countless combinations that you can create for templates. It is easy to customise the template to the age or learning level of your students.

Are crosswords good for students?

Crosswords are a great exercise for students' problem solving and cognitive abilities. Not only do they need to solve a clue and think of the correct answer, but they also have to consider all of the other words in the crossword to make sure the words fit together.

Crosswords are great for building and using vocabulary.

If this is your first time using a crossword with your students, you could create a crossword FAQ template for them to give them the basic instructions.
