What does the octet rule state?
The octet rule is a chemical rule of thumb that reflects the observation that main group elements tend to bond in such a way that each atom has eight electrons in its valence shell, giving it the same electronic configuration as a noble gas..
What are the 7 elements of life?
There are seven of them, namely:Element #1: Physical health.Element #2: Mental health.Element #3: Family health.Element #4: Financial health.Element #5: Vocational health.Element #6: Social health.Element #7: Spiritual health.
How do atoms become stable?
If the outer shell is filled, the atom is stable. Atoms with unfilled outer shells are unstable, and will usually form chemical bonds with other atoms to achieve stability. … In ionic bonds, atoms donate or receive electrons to achieve stability. In covalent bonds, atoms share electrons to achieve stability.
Do atoms want to be neutral?
However, remember that opposite charges attract and like charges repel: so, a positively charged atom will attract electrons until it becomes neutral, whereas a negatively charged atom will repel some of its electrons until it also becomes neutral. So only neutral atoms are stable. Hope these help!
What happens when an atom is unstable?
The unstable nucleus of radioactive atoms emit radiation. When this occurs, a new atom and element are formed. This process is called radioactive decay. It continues until the forces in the unstable nucleus are balanced.
Which type of bond is the weakest?
ionic bondThe ionic bond is generally the weakest of the true chemical bonds that bind atoms to atoms.
Can atoms be divided?
While the word “atom” literally means “indivisible,” the laws of quantum mechanics allow dividing atoms — similarly to light rays — and reuniting them. … Researchers from the University of Bonn have just shown how a single atom can be split into its two halves, pulled apart and put back together again.
Why do atoms want a full outer shell?
Atoms want a full outer shell because it completes all the gaps in the outside. With no gaps, other electrons don’t want to fit into those spaces. For example, a noble gas like Neon has a full outer shell. It doesn’t react with other chemicals because the electrons from other chemicals can’t fall in anywhere.
Why do atoms want to be stable?
An atom is stable because of a balanced nucleus that does not contain surplus energy. If the forces between the protons and the neutrons in the nucleus are unbalanced, then the atom is unstable. Stable atoms retain their form for ever, while unstable atoms undergo radioactive decay.
What are the 4 main atoms?
So though you may have heard that we are all stardust, that isn’t strictly true. The four most abundant elements in the human body – hydrogen, oxygen, carbon and nitrogen – account for more than 99 per cent of the atoms inside you.
How do you combine atoms?
Most interactions among atoms take place in the outermost shell of each atom. The number of each electron in this shell determines how an atom combines with other atoms to form compounds. When atoms combine they gain, lose or share electrons in such a way that the outer shells become chemically complete.
What is it called when atoms combine?
A molecule is formed when two or more atoms join together chemically. If atoms combine that are of two or more different elements, we call that a compound. All compounds are molecules, but not all molecules are compounds. When two hydrogen atoms combine with one oxygen atom, it becomes the compound water.
Are atoms extremely small?
Atoms are small. Really, really small. You’ll probably have heard that matter is made of bundles of these tiny things. You’ll likely also know that you can’t see them with the naked eye.
Do atoms contain empty space?
In reality, atoms do not contain any empty space. Rather, they are filled completely with spread-out electrons, making the shrinking of atoms impossible.
What do all atoms want to get?
Many other atoms are interested in gaining a few extra electrons. Oxygen (O) and fluorine (F) are two good examples. Each of those elements is looking for a couple of electrons to make a filled shell. They each have one filled shell with two electrons, but their second shells want to have eight.
How do atoms join together?
Atoms come together to form molecules because of their electrons. … When two atoms share electrons between them, they are locked together (bonded) by that sharing. These are called covalent bonds. Bonds like this are in oxygen gas, nitrogen gas, and hydrogen gas.
What is the difference between elements and atoms?
A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons. An element is a substance that is made entirely from one type of atom. … A compound is a substance made from two or more different elements that have been chemically joined.
What happens when two atoms collide?
When two beams collide, all that energy packed into such a small vacuum of space explodes and creates mass in the form of subatomic particles (think of Einstein’s famous equation: energy equals mass multiplied by the speed of light squared).
What are two exceptions to the octet rule?
However, there are three general exceptions to the octet rule: Molecules, such as NO, with an odd number of electrons; Molecules in which one or more atoms possess more than eight electrons, such as SF6; and. Molecules such as BCl3, in which one or more atoms possess less than eight electrons.

What is an atom with no charge called?
neutron: A subatomic particle forming part of the nucleus of an atom. It has no charge. It is equal in mass to a proton or it weighs 1 amu.
