Periodic table
What are transition elements?
Elements in groups 3 through 12 of the periodic, occur in nature as uncombined elements and include the iron triad and coinage metals
What is a covalent bond?
A covalent bond is between a non-metal and non-metal.
What are 4 properties of a substance that can be used to identify a substance?
Color, shape, size, and texture.
What is temperature?
The measure of the average kinetic energy of all the particle that make up an object
What is the definition of an atom?
Is the smallest particle of an elements that retains the elements properties.
How are elements on the periodic table arranged?
They are arranged by increasing atomic number, not atomic mass, and by periodic changes in physical and chemical properties.
What is used to show bond structures?
Dashes are used to show bond structures
What does a heterogeneous mixture consist of?
It consists of visibly different substances or bases.
When one object heats another, does the temperature increase of one object always equals the temperature decrease of the other object?
No, one object could have a great specific heat than the other object
True or False: Is a quark a type of atom?
True
What are 3 characteristics of the alkali metals?
One electron in outer shell, most reactive metals, stored in oil, used for health, photocells, softer than other metals. They could write any 3 out of these.
Why are noble gasses unusually stable?
The reason for this stability lies in the arrangement of the electrons
How are the particles in colloids?
Smaller but larger than solutions.
How does the motions of the particles that make up an object change when the object's temperature increases?
The particles start to separate and move faster as the temperature increases.
How do you find quarks?
Electric and magnetic fields accelerate charged particles, particles collide with and smash into protons.
What does a halogen become when they gain an electron from a metal?
it becomes a negative ions.
True or False: Is the number of protons the same number of electrons?
What is the appearance of a colloid?
May appear clear or cloudy but always scatter the light.
What is specific heat?
Amount of heat needed to raise the temperature of 1kg of a material 1 celsius.
What is the area around the nucleus of an atom called?
Electron cloud
What halogen own the characteristic of being rare, radioactive, and made for research purposes?
Astatine
Why are electric forces essential to forming compounds?
Because electric forces is what allows compound and bond to be formed
What does NaO stand for?
Sodium Oxide
What is the difference between temperature and thermal energy?
Temperature is the measure of the average kinetic energy of the particles whereas thermal energy is the sum of the kinetic and potential energy of the particles.
What quark is hard to detect?
The sixth quark
