Atomic Structure
This is the location where electrons are found in an atom.
What is the electron cloud?
The number of these subatomic particles determines an element's identity.
What are protons?
The vertical columns on the Periodic Table are called this.
What are groups or families?
This type of element is a good conductor of heat and electricity.
What is a metal?
This phase of the moon occurs when the Moon is positioned between the Earth and the Sun, making it invisible from Earth.
What is the New Moon?
Protons and neutrons are located in this central part of an atom.
What is the nucleus?
These electrons determine an element's chemical properties and reactivity.
What are valence electrons?
The horizontal rows on the Periodic Table are called this.
What are periods?
These elements are generally poor conductors and can be found on the right side of the Periodic Table.
What are nonmetals?
This phenomenon occurs when the Moon passes between the Earth and the Sun, blocking all or part of the Sun's light.
What is a solar eclipse?
This subatomic particle has a positive charge.
What is a proton?
Atoms of elements that have a full outer shell of electrons are very reactive. True or False?
False - They are not reactive
Elements in the same group share similar these.
What are chemical properties?
This element is a metalloid and is commonly used in computer chips. Similar to rubber.
What is silicon?
This event happens when the Earth moves between the Sun and the Moon, casting a shadow on the Moon.
What is a lunar eclipse?
These two subatomic particles have approximately the same mass.
What are protons and neutrons?
Elements in the same group/family have the same number of these electrons.
What are valence electrons?
The information that can be found in a period on the Periodic Table.
What is the number of energy levels?
This staircase-like line on the Periodic Table separates metals from nonmetals.
What is the metalloid line?
The tilt of Earth's axis combined with its orbit around the sun results in these yearly climatic patterns.
What are seasons?
In a neutral atom, the number of these is equal to the number of protons.
What are electrons?
This group of elements is known for being non-reactive gases. Name 2
What are noble gasses? Any 2 elements in group 18.
The element with atomic number 2, found in Group 18, a noble gas.
What is helium?
This rare metal is liquid at room temperature and is often used in thermometers.
What is mercury?
This effect, caused by the gravitational pull of the Moon, results in the rising and falling of Earth's oceans.
What are tides?
