How many elements does O 2 have?
two oxygen
Under standard conditions oxygen forms a gas that is composed of molecules consisting of two oxygen atoms (O2). This is called a diatomic gas.
Which element in Period 2 has zero Valency?
All the inert elements namely, Helium, Neon, Argon, Krypton have zero valency, except xenon and radon.
What element is in Group 2 period 6?
Barium is a chemical element with the symbol Ba and atomic number 56. It is the fifth element in Group 2, a soft silvery metallic alkaline earth metal.
What element has 2 protons 2 neutrons?
helium
Model of a helium atom’s nucleus with two protons and two neutrons. Helium is a relatively inert element, which when in its neutral state is quite unreactive due to a filled outer shell of electrons. Thus Helium is not normally part of chemical compounds.
Which elements in Period 2 are nonmetals?
Physical Properties of Period 2 Elements The elements on the right, nitrogen, oxygen, fluorine and neon all have low melting points and are all non-metals.
What element is in Group 2 Period 4?
The given element is calcium.
What are the properties of group 2 elements?

How many atoms does C12H22O11?
A molecule of sucrose (C12H22O11) has 12 carbon atoms, 22 hydrogen atoms and 11 oxygen atoms.
What are the post transition metals on the periodic table?
Post-transition metals are generally considered to be elements in Groups 13, 14, and 15. All of the classifications include the elements gallium, indium, tin, thallium, lead, and bismuth. However, depending on how “post-transition” is defined, this category may contain as few as six or as many as 22 elements.
Is there a PDF file of the valence periodic table?
The IUPAC defines valence to be the maximum number of univalent atoms (such as hydrogen or chlorine atoms) that may combine with an atom of the element. Keep in mind, the valence is the maximum number of bonds, not the usual number of bonds. You can download and save or print the pdf file of the valence periodic table.
Can you print the electron configuration periodic table?

When was the interactive periodic table of elements created?
Interactive Periodic Table of Elements The periodic table of the elements was first introduced in the mid-19th century by Dmitry Mendeleev. He organized the elements by atomic number, which is equal to the number of protons found in the nucleus of the element’s atoms.
