How atoms in a group are similar?
Groups, in the periodic table of elements, are elements that all have the same number of valance electrons, which in turn tells us a lot about the kinds of chemical reactions that these elements will or will not undergo.
When at atom is charged it us called an ion how many electrons are in 02?
O2 has 16 electrons. Each oxygen atom has 8 electrons, and since O2 is a molecule made of two oxygen atoms, the total number of electrons is 16.
What is the NCO- Lewis structure and how does it represent the bonding and electron distribution in the molecule?
The NCO- Lewis structure shows the arrangement of atoms and electrons in the NCO- ion. In this structure, nitrogen is bonded to carbon and oxygen through single bonds, with a lone pair of electrons on the oxygen atom. This representation helps us understand how the atoms are connected and how the electrons are distributed in the molecule.
Does valence tell us to what extent an atom can combine?
Valence refers to the number of electrons an atom can either gain, lose, or share in order to achieve a stable electron configuration. It helps determine how an atom can combine with other atoms to form chemical bonds.
Ask us anythingMetallic bonds are formed from the sharing of valence electrons.?
That's correct! Metallic bonds are formed between metal atoms when valence electrons are delocalized and shared among the metal ions, creating a sea of electrons that hold the metal atoms together. This sharing of electrons allows metals to conduct electricity and heat well, as the free-moving electrons can easily carry electrical currents and energy through the material.
What is the total number of valence electrons in all the atoms in li3n?
Li3N is lithium nitride, an ionic compound. Lithium, being an alkali metal, has 1 valence electron. The "3" subscript means there are 3 of them. Nitrogen is a non-metal with 5 valence electrons. This means it needs 3 more to satisfy the octet rule, which it gets from the 3 lithiums. So, nitrogen's 5 plus lithium's 1 (times 3) = a total of 8 valence electrons.
What does the name diphosphorus pentoxide tell us?
Tells us there are 2 phosphorus atoms and 5 oxygen atoms
What does the group number of A tell us about the valence electrons?
no

What does the number of electrons on the outershell of an atom tell us?
The valence of the element
Why do atoms give us electricity?
Electrons can be made to move from one atom to another. When those electrons move between the atoms, a current of electricity is created. The electrons move from one atom to another in a "flow." One electron is attached and another electron is lost.
How can you find group no?
The number of valence electrons tell us the group number of that element.
What does temperature tell us about atoms?
Temperature is related to the average energy per particle.
When at atom is charged it us called an ion how many electrons are in 02?
O2 has 16 electrons. Each oxygen atom has 8 electrons, and since O2 is a molecule made of two oxygen atoms, the total number of electrons is 16.
What is everything around us made of?
Everything around us is made up of atoms. Atoms are the basic building blocks of matter and consist of protons, neutrons, and electrons. Different combinations of atoms form molecules, which in turn make up different substances and materials.
What things are made up of atoms?
Everything! Atoms are in the air, water, and even us ! Atoms are are the elementary chemically indestructible components of any material in the world. Atoms are the bricks of molecules.
What do electrons have to do with chemical bonds?
Each element has shells of electrons and they are limited to how many can be shared in the outer shell. This lets us know what and how many atoms can combine with it. Hydrogen has the need for one electron in its outer shell. Oxygen has the need for two more electrons in its outer shell. Therefore, 2 hydrogen atoms can combine with oxygen.
