What else can I help you with?
What happens to the electron cloud with increasing periods number?
The electron cloud increases the amount of valence shells it has with the increase of electrons in the atoms
The happy atoms are the blank gases They dont react because blank?
The happy atoms are the noble gases. They don't react because their valence electron shells are full. The goal of every element is to have the most outer shell of electrons full. The first shell holds 2 electrons, and every shell after that holds 8 electrons. So helium and hydrogen both want to have 2 electrons in their outer shells. Elements like neon and argon have 8 electrons in their outer shells. Atoms like chlorine and fluorine have 7 electrons in their outer shells. This means that aren't "happy" because they want to have 8. This is why they ionically bond with atoms like sodium that have 1 electron in their outer shells. Sodium gives that electron to chlorine and now both have 8 electrons in their outer shells.
Why are atoms more likely to lose an electron as you go down a group?
this occurs because of the shielding effect of inner electrons.as we go down the group- number of electronic shells increases, which restricts the outer most electrons from being attracted by the protons of nucleus.as the result of this effect the outer most electrons are loosely attracted by the nucleus,resulting the increase of atomic radii.hence making it easier for atoms to lose electrons down the group.
Explain what atoms are trying to achieve in there electron shells when they bond with each outher?
Atoms are trying achieve a stable electronic configuration i.e., stable arrangement of electrons in their electron shells. All configurations are not stable. Mostly stable configuration is attained by forming an octet of electrons in outer most shell. Sometimes octet rule is violated also.
When atoms of different elements share electrons they form?
a chemical bond known as a covalent bond. In a covalent bond, atoms share electrons in order to achieve a stable electron configuration. This sharing of electrons allows atoms to fill their outer electron shells and become more stable.
Atoms with many electron shells will let go of their electrons more easily than those with fewer shells.?
true
Where do electrons collect?
Electrons collect in the outer energy levels of atoms, known as electron shells. These shells are organized around the atomic nucleus and can hold a specific number of electrons based on the atom's atomic number and electron configuration.
What is the chemical behavior of atoms whose outer electron shells contain 8 electrons?
These atoms are very stable and unreactive.
Do atoms whose outer elecron shells contain eight electrons tend to form ionic bonds in aqueous solutions?
Atoms whose outer electron shells contain eight electrons tend to be stable and do not easily form ionic bonds in aqueous solutions. This is because they have reached the stable configuration known as the octet rule. In most cases, atoms that form ionic bonds have outer electron shells that are not fully filled with eight electrons.
What happens to the electron cloud with increasing periods number?
The electron cloud increases the amount of valence shells it has with the increase of electrons in the atoms
How the number of electrons in an atoms electron shells is the basis for chemical bonding?
Atoms bond because they "share" their electrons. Every atom wants to have 2 atoms in their first shell, and then 8 in all the other shells. Lets say we have an atom with 3 electrons, and one with 9 electrons, they will esaly bond
Why does oxygen have two shells?
Oxygen has two electron shells because it has eight electrons in total, with two in the first shell and six in the second shell. Atoms tend to fill their outermost electron shell to achieve stability, and oxygen does this by sharing electrons with other atoms or gaining electrons to fill its outer shell.
The happy atoms are the blank gases They dont react because blank?

How energy stored in molecules and atoms?
In atoms, whenever energy is supplied to it an electron or the required group of electrons traverses to higher level shells.
If an atom such as hydrogen is able to form covalent bond describe what happens when the electrons shells of two atoms overlap?
When the electron shells of two atoms overlap to form a covalent bond, the electrons are shared between the atoms. This sharing allows the atoms to achieve a more stable electron configuration by filling their outermost energy levels. This sharing of electrons creates a bond between the atoms, enabling them to stay together as a molecule.
Why are atoms more likely to lose an electron as you go down a group?
this occurs because of the shielding effect of inner electrons.as we go down the group- number of electronic shells increases, which restricts the outer most electrons from being attracted by the protons of nucleus.as the result of this effect the outer most electrons are loosely attracted by the nucleus,resulting the increase of atomic radii.hence making it easier for atoms to lose electrons down the group.
Are atoms really sharing electrons?
Atoms which form covalent bonds do share electrons. An example would be the atoms in a water molecule. Yes, the electrons are really shared.
