Random periodic table questions
100
Who designed the current Periodic table of elements
The Russian Dimitri Mendeleev created the Periodic table of elements in 1871.
100
What are the properties of Transition metals
Are very strong and usually stable, and have 1-2 valence electrons
100
What is a element
A element is a pure substance that cannot be broken down by any means (chemical or physical)
100
How many element groups are there
There is 18 groups on the periodic table, they are vertical lines on the table
100
How many protons would Carbon have with a atomic mass of 12 and number of 6
It would have 6 protons, to find the number of protons in a element you subtract the atomic number from the atomic mass
200
What shows the number of protons of the element
Atomic number shows the number of protons in an element, it is located on top of the chemical symbol
200
The Oxygen family has how many more valence electrons than the Boron family
3 is the difference, The properties of Boron family states it only has 3 valence electrons and he Oxygen has 6
200
Which of the following listed substances are not elements Gold - Water - Oxygen - Kryptonite - Einsteinium
Water and Kryptonite are not elements, water is a compound formed of Hydrogen and Oxygen and kryptonite is a movie crystal that can kill Superman, Gold, Oxygen and Einsteinium are all known elements
200
What are periods on the periodic tables
Periods are the horizontal lines of the periodic table and show the number of valence electrons in the element
200
What are Valence electrons
Valence electrons show the number of electrons in the outer shell
300
What are elements 57-70 and 89-102 and why are they located under the table
They are the Rare earth metals, the reason they are located where they are is the fact there is not enough space to put them with the other elements.
300
The Halogen properties state that halogens are the most reactive _______ and bond with _________?
Non-metals and will bond with alkali metals because they have an extra electron
300
What is the rarest element Radium - Oxygen - Astatine - Argon - Potassium - Hydrogen
Astatine is the least common element known to us, it is part of the halogen family and is highly unstable and so only 1 ounce can exist on Earth at one time
300
Argon would be have how many valence electrons - 2 - 16 -8 - 4
Argon would have 8 valence electrons and is found in the 3rd period of the periodic table
300
How did Dimitri Mendeleev design the Periodic table of elements
He designed the table of elements by putting them in order of the atomic weight and properties
400
How many elements are in the periodic table
118 known elements are found on the current table, of which 102 occur naturally
400
What family is the only one to have a complete shell?
Noble Gases are the only ones and so they will not bond with other elements under normal conditions
400
What are the first 10 elements of the periodic table
Hydrogen - Helium - Lithium - Beryllium - Boron - Carbon - Nitrogen - Oxygen - Fluorine - Neon are the first 10 elements on the table
400
Halogens are most likely to bond with which group of elements
The Alkali metals have a extra electron, to to get rid of the full outer shell they give a electron to the halogens giving both a full outer shell
400
All living things are made up mainly of these four elements
Carbon, nitrogen, oxygen and hydrogen make up every living thing on this earth from ants to us to whales, elements make up everything
500
What are the the 3 metal groups
Metals, metalloids and non-metals are the three main groups on the table, metals are the largest in amount with metalloids the least
500
What are the differences between non-metals, metalloids and metals
non-metals are usually gases and are not good conductors, metals are malleable and good conductors and metalloids an have properties of both and are semi-conductors
500
Which element of the following does not exist - Einsteinium - Augustium - Seaborgium - Rutherfordium - Mendelevium - Californium - Bohrium
Augustium is a made up element , the others do exist Bohrium - Named after Charles Bohr (element 107) Einsteinium - Named after Albert Einstein (element 99) Californium - Named after California (element 98) Mendelevium-Named after Dimitri Mendeleev (element 101) Seaborgium - Named after Glenn T. Seaborg (element 106)
500
Name 3 of the 6 elements found under "Noble gases"
Noble gases are the last group on the table, the elements listed under the name are Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe) and Radon (Ra) Helium (He)
500
There are 9 metalloids on the step-ladder, name me 5
Aluminum, Silicon, Boron, Germanium, Arsenic, Antimony, Trillium, Polonium, Astatine are all metalloid metals also 2 elements from the families of the Boron, Carbon, Nitrogen, Oxygen and Halogen
