True. Atoms with unfilled outer shells can achieve stability by either sharing, gaining, or losing electrons during chemical reactions. This process allows them to attain a full outer shell, which is often associated with lower energy and greater stability. This behavior is fundamental to the formation of chemical bonds, such as covalent and ionic bonds.

What role do electrons play on determining the stability of an atom?

The role electrons play in stabilizing an atom is they balance out the charge of the protons. If an element has more protons than electrons, it has a positive, not neutral, charge, and vice versa. Unpaired electrons can cause an element to be chemically reactive and/or radioactive. Hope this helps!


How does the number of valence electrons change?

There is no simple answer to your question, as your question is too broad and undefined. For simple atoms, the number of valence electrons is the number of electrons in unfilled electron shells, which are then available for bonding to another atom. Oxygen with 8 total electrons has 6 paired electrons in filled electron orbitals, and 2 valence electrons in unfilled orbitals. That is why it forms bonds with 2 hydrogen molecules to form water (H2O) The number of valence electrons can change when you add or remove electrons from an atom, or in more complex atoms where filled orbitals to unfilled orbitals have the same energy and electrons can move from one to another depending on the number of other atoms it is binding with.


What is the difference between a filled and an unfilled orbital?

A filled orbital has either 2 electrons (if it is the first shell of an atom) or 8 electrons. This is the highest number of electrons these shell can hold Every orbital tends to complete itself to form a stable element. A filled orbital could be any orbital, either 1st, 2nd, second last or last shell of the atom. An unfilled orbital always has atleast one less electron than the shell can hold. It is always the last shell of an atom and always makes the atom unstable as atom tends to acquire inertness by trying to get this unfilled oribital filled.


What determines the properties of an element?

The three factors determine the chemical properties of an element:The number and arrangement of electrons in an atomThe number of valence electronsThe number and arrangement of electrons

What is the reactivity of an atom determined by?

The reactivity of an atom is determined by the number of electrons in its outer energy level (valence electrons). Atoms with incomplete valence shells tend to be more reactive as they seek to gain, lose, or share electrons to achieve a stable electron configuration. Electrons in the outermost energy level are involved in chemical reactions.

Why conduction band and valence band partially filled?

No. Conduction band is basically the unfilled energy levels into which electrons can be excited to provide conductivity.

What part of the atom determines how it will react with other atoms?

These particles are the electrons.


Do valence electrons affect the reactivity of an element?

atoms are most stable when they have filled the outer shell of electrons which normally holds a max of 8. so if an atom has 1 electron in its outer layer getting rid of it will give him stability, in much the same way having 7 electrons will mean gaining one electron will give it stability. now lets say the two meet, they react with each other and everybody is happy. It is thought than when two elements react, they are trying to acheive a "perfect" electronic configuration (i.e. have a full outer shell). The more electrons needs to lose/gain before acheiving this stability determines its reactivity.


How many electrons are in the third principal level of a chromium atom?

There are eight electrons in the third level of a chromium atom.There are four level in the chromium atom, and the fourth level, unfilled, contains 6 out of 18 electrons, in the neutral, non-ionized atom.


How many unfilled electron positions are in a carbon atom?

Carbon has an atomic number of 6, therefore the first valence shell is filled with two of the electrons, leaving four electrons and eight empty spaces on the second valence shell. So... 4 XD Hope this helped


What makes elements similar?

By elements being similar, I assume you mean elements of the same group being similar rather than all elements in general. Elements of the same group are similar in terms of chemical properties because they share a similar electron configuration. For instance group one of the periodic table, the alkali metals, has only one electron in its outermost unfilled orbital. Because chemical reactions are dependent on the exchange and sharing of electrons, the similarity of electron configuration in elements of a group results in them having similar properties. For instance, the alkali metals are all soft and extremely reactive.
