What is the group of sodium?
Alkali Metals
What is the name of each group on the periodic table?
Groups are numbered 1–18 from left to right. The elements in group 1 are known as the alkali metals; those in group 2 are the alkaline earth metals; those in 15 are the pnictogens; those in 16 are the chalcogens; those in 17 are the halogens; and those in 18 are the noble gases.
What is Group 2 called in the periodic table?
alkaline earth metals
What is Group 7 on the periodic table called?
the halogens
Is Group 7 and 17 the same?
Group 7 (IUPAC group 17) is a vertical column on the right of the periodic table . The elements in group 7 are non-metals called the halogens .
What is Group 0 called?
the noble gases
What are the Group 3 elements called?
Group 3A (or IIIA) of the periodic table includes the metalloid boron (B), as well as the metals aluminum (Al), gallium (Ga), indium (In), and thallium (Tl). Boron forms mostly covalent bonds, while the other elements in Group 3A form mostly ionic bonds.
Why is it called Group zero?
Nobel gases are called zero group element because they are completely inert in form which doesn’t form any compounds. They are octet in nature which makes them stable and unable to gain or lose electrons.
Why is it called Group 0?
The noble gases are colorless, odorless, tasteless, and nonflammable under standard conditions. They were once labeled group 0 in the periodic table because it was believed they had a valence of zero, meaning their atoms cannot combine with those of other elements to form compounds.
Why is group 0 so unreactive?
When elements react, their atoms complete their outer shells by losing, gaining, or sharing electrons . Atoms of group 0 elements already have stable arrangements of electrons. This means that they have no tendency to lose, gain, or share electrons. This is why the noble gases are unreactive.
What is another name for Group 7 elements?
The Group 7 elements are called the halogens. They are placed in the vertical column, second from the right, in the periodic table . Chlorine, bromine and iodine are the three common Group 7 elements.
What are the Group 0 elements?
Group 0 contains non-metal elements placed in the vertical column on the far right of the periodic table . The elements in group 0 are called the noble gases . They exist as single atoms .
What are Group 8 elements called?
Group 8A — The Noble or Inert Gases. Group 8A (or VIIIA) of the periodic table are the noble gases or inert gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). The name comes from the fact that these elements are virtually unreactive towards other elements or compounds.
Which is the rarest of rare element on Earth?
element astatine
What are the first 5 elements in Group 0?
The Group 0 elements, the NOBLE GASES consist of helium, neon, argon, krypton, xenon and radioactive radon.
What groups have a full outer shell?
The group (family) with elements cotaining full outer shells are the right-most group on the table: the noble gases: helium, neon, argon, krypton, xenon, and radon (element 118, oganesson, also belongs in this group, but most all of its chemical and physical properties are as of yet unknown.
Are Group 7 elements reactive?
Reactivity of group 7 non-metals increases as you go up. Each outer shell contains seven electrons and when group 7 metals react, they will need to gain one outer electron to get a full outer shell of electrons. This allows an electron to be attracted more readily, making it more reactive as you go up the group.
What are the properties of Group 7 elements?
The halogens have low melting points and low boiling points. This is a typical property of non-metals. Fluorine has the lowest melting and boiling points. The melting and boiling points then increase as you go down the group.
What does Group 7 have in common?
Elements in group seven have a number of similar properties, most importantly they have low melting and boiling points. This is of course a typical property of non-metals. From the lowest boiling and melting point to the highest, the group in order is fluorine, chlorine, bromine, iodine and astatine.
What is the trend in Colour in Group 7?
The melting points and boiling points of the halogens increase going down group 7, and their colour gets darker.
