What are periods and groups?
Elements in the periodic table are arranged in periods (rows) and groups (columns). Atomic number increases as you move across a row or period. The period number of an element signifies the highest unexcited energy level for an electron in that element. Elements within a group share several common properties. Groups are elements have the same outer electron arrangement. The outer electrons are called valence electrons.
In the second short period of the Periodic Table what do the elements have in common?
- low atomic and mass number - low atomic weight - six nonmetals and two metals
What information will an elements atomic number give you?
Atomic no. helps to know 1. the position of element in the periodic table2. Common properties3. Electronic Configuration4. Common electrovalencies and oxidation states.5. Many other properties.
What does platinum gold and mercury have in common?
They are all metals in the 6th row of the periodic table - consecutive in fact. Atomic number Platinum (Pt):78 Atomic number Gold (Au): 79 Atomic number Mercury (Hg): 80
Why is hydrogen weird?
Hydrogen is the first element on the periodic table. It has an atomic number of 1. It is highly flammable and is the most common element found in our universe.
Does the periodic table gives the mass number of the most common isotopes of an element?
The periodic table give the atomic numbers and the atomic weights of chemical elements.

What do horizontal rows have in common?
All of the elements in a given horizontal row (or period) have the energy level, but they differ in the number of valence electrons.

What are the horizontal groupings in the periodic table named?
The horizontal lines are called "periods" and show how many "shells" each atom hasThe horizontal rows in the periodic table are called periods. The vertical columns are called groups.
What do rows have in common in the periodic table?
Elements of same row has equal number of shells.
Who is knownas the fatherof the periodic table?
Dmitri Mendeleev. He was the first scientist to arrange the elements based on their atomic number, as well as common properties.
What does platinum gold and mercury have in common?
They are all metals in the 6th row of the periodic table - consecutive in fact. Atomic number Platinum (Pt):78 Atomic number Gold (Au): 79 Atomic number Mercury (Hg): 80
What are columns called in a periodic table and what do they have in common?
colums are called "families" or "groups". They are all placed in order according to the atomic number, and valend electrons
Why is hydrogen weird?
Hydrogen is the first element on the periodic table. It has an atomic number of 1. It is highly flammable and is the most common element found in our universe.
What is true of the properties of the elements in the same period of the periodic table?
Depending on the block it may be increasing or decreasing acidity, atomic radii varies through periods, atomic number increases by 1 with each element, ... as to reactivity, elements of lower periods are almost all radioactive, as with a heavier nucleus nuclear stability decreases. Hope this answers your question! :D
