What else can I help you with?
Which element has 1 valence electron and is in period 1.?
The element with 1 electron in period 1 would be hydrogen.
What is the first element in a period called?
Hydrogen
What is the diatomic element in period 1 in periodic table?
The diatomic element in period 1 of the periodic table is hydrogen (H). It exists as H2, meaning two hydrogen atoms are bonded together.
How many outer electrons do the metals in the first period have in the periodic table?
There are no metals in the first period. Only hydrogen and helium.
What is the first element in the first period in the periodic table?
hydrogen
An fact about hydrogen?
Hydrogen is the only element in the first period to not have a full outer energy level.
How can valency change across a period?
Valency, or the combining capacity of an element, can change across a period due to variations in the number of valence electrons. As you move from left to right across a period in the periodic table, elements typically gain more valence electrons, transitioning from metals to non-metals. This change influences their ability to form bonds, with metals often having low valency and non-metals having higher valency. Consequently, the types of chemical bonds and compounds that elements can form also vary across the period.
What period of the periodic table is hydrogen in?
Hydrogen is technically classed as a group one element, as it only has one electron!
What is the classification hydrogen?
Classification of hydrogen is: group 1, period 1 in the periodic table of Mendeleev; hydrogen is the first element in this table.
Which element is located in period 1 of the periodic table?
Period 1 refers to the top row of the periodic table. These elements are Hydrogen and Helium.
The first element in a period is always an active?
That is not true. The first element in a period may be active or inactive, depending on the specific electron configuration of the element. For example, the first element in period 1, hydrogen, is not considered an active element.
What does every element in the first period have?
i dont know i was waiting for u to tell me.....
