What are the horizontal rows in the periodic table called?

Elements are arranged in order of increasing atomic number, their physical and chemical properties show a periodic pattern. The horizontal rows are called periods. Each period contains more elements than the previous one.

What three families are found in the center of the periodic table?

The three families that are found in the center portion of the periodic table are the Iron group, the Cobalt group and the nickel group. There are 18 families in the periodic table.

Is Group 4 metal or nonmetal?

The non-metals in this family react by gaining 4 extra electrons through the formation of covalent bonds (sharing bonds). Group 4 elements are also called the carbon group elements. Members of this group include: Carbon.

What is Group 5 called?

Group 5A (or VA) of the periodic table are the pnictogens: the nonmetals nitrogen (N), and phosphorus (P), the metalloids arsenic (As) and antimony (Sb), and the metal bismuth (Bi).

What is Group 6 called?

What is Oxygen’s weakness?

Her strengths are that she is able to help people in need, but she can also take oxygen away. Her weaknesses are when she is high up in the air and there is little oxygen in the air, it makes her dizzy.

What makes oxygen unique?

Oxygen is a nonmetal. It has low thermal and electrical conductivity, but high electronegativity and ionization energy. The solid form is brittle rather than malleable or ductile. The atoms readily gain electrons and form covalent chemical bonds.

Who named Oxygen?

Antoine-Laurent Lavoisier

What are 3 uses for oxygen?

Common uses of oxygen include production of steel, plastics and textiles, brazing, welding and cutting of steels and other metals, rocket propellant, oxygen therapy, and life support systems in aircraft, submarines, spaceflight and diving.

Who is the mother of chemistry?

Marie Anne Paulze Lavoisier
