Combustion,Heat and Energy
Can you light diamond on fire?
yes it can set on fire since it is made of carbon
what is the atomic structure?
the constitution of it nucleus and the arrangement of the electrons around it
Where is a metal located in the Periodic table ?
it is located in the left side of the Periodic table
What makes a chemical bond ?
When atoms share or tranfer valence electron from one to another
What elements make water?
Hydorgen 2 Oxygen is water
How do volcanoes start?
They start by rocks slowly melting and becomes a think flow of a substance called magma
how does the bohr model work?
The bohr models shows the atom as a central nucleus containing protons and neutrons with the electron in circular orbitals at specific distance from the nucleus
Where is non-metals located ?
how are ions made from neutral atoms?
An atom that picks up a charge by gaining or lose electrons
how do you write ionic formulas?
First you write the symbol and charge of the cation(metal), then the anion(nonmetal) second
What elements are needed to cause a fire ?
Oxygen, heat and Fuel
What differentiates atoms from each other?
what makes them different from each other is their number of protons
how does the arrangement of the periodic table demonstrate trends in elements?
moving left or right within a row, the atoms could either get smaller or larger in size and there reactivities could either go up and down
how colvalent bonds formed?
Colvalent bonds are formed When pairs of electrons are shared by atoms
what is a subcript used in a chemical formula
They are tiny numbers set below an elements tellings us how many atoms are in the molecule
How are minerals formed ?
Minerals are formed when hot gases or molten rocks cool or when heat or pressure change pre-existing minerals
How does the emission spectra for elements relate to the electron energy levels?
The spectrum of frequencies of eletromagnetic radiation emitted due to electrons making a transition emitted due to electrons making a transition from a high energy state to a lower energy state
when and who created the periodic table ?
it was created 1869 by a russian chemist by the name of dimitri mendeleev in 1869
what is the difference between polar and non-polar ?
polar is un-even Eletrons and non-polar is even electrons
what is the difference between ionic and convalent compounds?
Ionic compound are usually formed when a metal reacts with a nonmetal, and covalent bonds are formed when two nonmetal react with each other
How does the forest fire model energy flow of fuel combustion?
Are there nuclear reactions going on in your body? and what they do?
yes, there are nuclear reactions constantly occurring in our bodies but there is few compared to the chemical reaction
who was the guy who discovered Beryllium ?
The guy was named Nicholas louis Vauquelin
how many pairs of eletrons are in sodium ?
11 electrons
How do you determine if a compound is an ionic compound or a covalent compound?
Compounds that involve to a metal binding with either non-metal or semi metal well be consider as a ionic bonding
