What does Period 2 have in common?
All of the elements in a period have the same number of atomic orbitals. For example, every element in the top row (the first period) has one orbital for its electrons. All of the elements in the second row (the second period) have two orbitals for their electrons.
Where is Period 2 in the periodic table?
The horizontal rows of the periodic table are called periods. Period 2, or the second period, refers to the second row from the top of the periodic table.
Why is oxygen in the periodic table?
A very reactive element, oxygen (O) belongs to the non-metals family in the periodic table which consists of elements such as carbon (C). One of the most abundant elements in the universe, oxygen reacts with the vast majority of other elements of the periodic table to form oxides.
What period is oxygen on the periodic table?
Period 2

Which general trend is found in period 2 on the periodic table as the elements are considered in order of increasing atomic number?
As the elements in Period 2 of the Periodic Table are considered in succession from left to right, there is a decrease in atomic radius with increasing atomic number.
What element in Period 2 has the most mass?
The element in Period 2 with most mass is clearly the element with the highest atomic number, Z , and that is Ne , Z=10 , 21.08⋅g⋅mol−1 .
What is oxygen in the periodic table?
oxygen (O), nonmetallic chemical element of Group 16 (VIa, or the oxygen group) of the periodic table.
What element is Group 2 period 2?
Answer: Berilium. Berilium is located in period 2 group2.
What occurs as the atomic number of the elements in Period 2 increases?
What occurs as the atomic number of the elements in Period 2 increases? (1) The nuclear charge of each successive atom decreases, and the covalent radius decreases. The nuclear charge of each successive atom increases, and the covalent radius decreases.
Is oxygen a metal or nonmetal or metalloid?
Oxygen, carbon, sulfur and chlorine are examples of non-metal elements. Non-metals have properties in common. They are: poor conductors of heat and electricity (they are insulators )
Where is oxygen located on the periodic table?
Oxygen’s location in the periodic table of the elements. Oxygen is the 8th element on the periodic table. It is located in period 2 and group 16. To find it, look toward the upper righthand top side of the table.
What does period 2 on the periodic table mean?
The horizontal rows of the periodic table are called periods. Period 2, or the second period, refers to the second row from the top of the periodic table. The elements in period 2 of the periodic table are: Name of Element. lithium. beryllium.
How are elements laid out on the periodic table?
The periodic table is laid out in rows to illustrate recurring (periodic) trends in the chemical behavior of the elements as their atomic number increases; a new row is started when chemical behavior begins to repeat, creating columns of elements with similar properties.
How many electrons does a period 2 element need?
Period 2 elements obey the octet rule in that they need eight electrons to complete their valence shell. The maximum number of electrons that these elements can accommodate is ten, two in the 1s orbital, two in the 2s orbital and six in the 2p orbital.
