The ion is called an ox ide ion. The name of a non-metal ion is different to the name of its element:. Fluorine is in group 7. It has atomic number 9 and mass number Group 7 non-metals attract an extra electron to complete their outer shell.
The outer electron shell gets further from the nucleus moving down the group. This means that the extra electron is less strongly attracted, so the reactivity of group 7 gets less going down the group. What are the units used for the ideal gas law?
How does Charle's law relate to breathing? What is the ideal gas law constant? How do you calculate the ideal gas law constant? How do you find density in the ideal gas law?
Does ideal gas law apply to liquids? Even though you find complex names on other molecules, everyone calls H 2 O "water". Water is made up of two hydrogen H atoms and one oxygen O atom. The formula for water is H 2 O.
The hydrogen atoms have filled orbitals with two electrons and the oxygen atom is filled with eight electrons. Chem4Kids Sections.
