What is a period in a periodic table?
The horizontal rows of the periodic table are called periods. Each period corresponds to the successive occupation of the orbitals in a valence shell of the atom, with the long periods corresponding to the occupation of the orbitals of a d subshell.
What is a group and period in periodic table?
All the different elements are arranged in a chart called the periodic table. Here are the main features of the table: the horizontal rows are called periods. the vertical columns are called groups.
What is another word for period on the periodic table?
In the periodic table of elements, there are seven horizontal rows of elements called periods. The vertical columns of elements are called groups, or families. The most common way the periodic table is classified by metals, nonmetals, and metalloids.
What is the period for helium?
Period 1
What is Period 1 called?

| Hydrogen | Rubidium |
|---|---|
| Strontium | |
| Yttrium | |
| Zirconium | |

Why is Period 1 the shortest period?
Period 1. The first period contains fewer elements than any other, with only two, hydrogen and helium.
Which period has only gases?
period 1
Why can Period 1 only have 2 electrons?
This is because in quantum physics, this period fills up the 1s orbital. Period 1 elements follows the duet rule, they only need two electrons to complete their valence shell. These elements can only hold two electrons, both in the 1s orbital. Therefore, period 1 can have only two elements.
What do you call the element from atomic number 57 71?
Lanthanoid, also called lanthanide, any of the series of 15 consecutive chemical elements in the periodic table from lanthanum to lutetium (atomic numbers 57–71).
What is the only metal that is a liquid?
Mercury
Which metal is kept in kerosene oil?
Sodium and Potassium are highly reactive metals and react vigorously with the oxygen, carbon dioxide and moisture present in the air such that it may even cause a fire. To prevent this explosive reaction, Sodium is kept immersed in kerosene because Sodium doesn’t react with kerosene.
Which liquid metal is the best conductor?

Iron is the most abundant transition metal in the human body.
Which is the least metal in human body?
All of the mass of the trace elements put together (less than 10 grams for a human body) do not add up to the body mass of magnesium, the least common of the 11 non-trace elements.
Which metal is present in the human body?
Among the metals that are currently known to be essential for normal biological functions in humans are sodium (Na), potassium (K), magnesium (Mg), and calcium (Ca) that belong to main group of elements, and vanadium (V), chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn).
Which metal is present in human body?

Which is the smallest bacteria or virus?
The smallest bacteria are about 0.4 micron (one millionth of a meter) in diameter while viruses range in size from 0.02 to 0.25 micron. This makes most viruses submicroscopic, unable to be seen in an ordinary light microscope.
