Atomic Concepts
I am the atomic theory that used an experiment to discover the atom's nucleus,
Why was Mendeleev's table considered the FIRST periodic table?
What is Mendeleev's table allowed for prediction of undiscovered elements?
The specific temperature at which a material changes from a solid into a liquid.
What is melting point?
Which group is the Alkali Family?
What is the first group?
I am an Oxygen(8) Atom. How many valence electrons do I have?
I am the atomic theory that determined that electrons don't not orbit around the nucleus like planets and INSTEAD rapidly within a region around the nucleus.
What is the cloud model?
How did Mendeleev arrange elements in his periodic table?
What is by increasing atomic mass?
A state of matter that has no fixed shape or volume and its particles are far apart and move rapidly in random directions.
What is gas?
What is the transition metals?
How many electrons can fit in the first shell?
What is 2?
I am the atomic model that thought matter was formed of small, 3d shapes that could not be cut into smaller parts.
What is Democritus?
How are elements arranged in the modern periodic table?
What is by increasing atomic number?
A state of matter where particles are tightly packed together, giving it a definite shape and volume.
What is a solid?
What family is made up of almost all elements in a non-solid state of matter?
What is the noble gases?
How many valence electrons does an atom of silicon(14) have?
What is four?
I am the atomic model that discovered atoms have negatively charged particles called electrons.
What is Thompson's model?
Which group of elements was not included in Mendeleev's periodic table, but is present in the modern table?
What is the noble gases?
The change of a substance from the solid phase to the gaseous phase without entering into the liquid phase.
What is sublimation
What is the element with the smallest atomic mass in the non metal family?
What is hydrogen?
How many electrons can fit in the third shell?
What is up to 18?
I am the atomic theory that says atoms cannot be divided or split and that every element's atoms are exactly the same.
What is Dalton?
What important finding does the periodic table take into account, that did not exist when Mendeleev created his periodic table?
What is isotopes?
A material’s ability to be drawn into a thin wire.
What is dultile?
I am the family with all three states of matter represent.
What is the halogen family?
What is the relationship between an element's group number on the periodic table and its number of valence electrons?
What is the group number directly corresponds to the number of valence electrons an element has?
