What Determines The Reactivity Stable Or Unstable Of An Atom

More Answers On What Determines The Reactivity Stable Or Unstable Of An Atom

What Determines an Atom’s Reactivity? – Reference.com

An atom’s reactivity is determined by the number of electrons in its outermost shell. Because the outer shell can hold up to eight electrons and not all elements are able to fill these shells to capacity, the fullness of the shells will determine the volatility of the atom’s reactive properties as a result of the number of electrons required to complete the shell.

What determines stability or reactivity of an atom? – Weebly

Here is the answer I came up with: The stability of an atom is determined by, the amount of energy an atom has. An atom that has less energy has greater stability compared to an atom with more energy, that is less stable. When an atom has a reaction that releases energy as heat or light, the stability of the atom increases.

What makes an atom stable or unstable? – Quora

Answer (1 of 6): An atom is stable or unstable depending on the forces of the particles within the atom that make up the nucleus. A stable atom has forces among the particles balanced out. To achieve this balance atoms must have equal amounts of protons and neutrons. An unstable atom occurs when …

Reactivity of Elements of the Periodic Table

Jun 19, 2021Reactivity is a measure of how easily an element will combine with other elements to form compounds. Some elements are unreactive and need energy putting in others will react spontaneously and easily. The size of the nucleus determines the chemical reactivity of the element due to its ability to hold onto electrons and attract electrons.

Stability of atoms Flashcards – Quizlet

A full outer shell results in a stable unreactive atom. Anything less than a full outershell results in an unstable reactive atom. The most reactive atoms are those with only one electron in their outer shell. Group one in the periodic table all have 1 electron in their outer shell. They are all reactive soft metals.

Stable and unstable nuclei – Radioactive decay and half-life – CCEA …

Stable and unstable nuclei The balance of protons and neutrons in a nucleus determines whether a nucleus will be stable or unstable. Too many neutrons or protons can upset this balance making the …

How do valence e- determine an element’s reactivity? | Socratic

Explanation: Your valence electrons refers to the electrons sitting on the outermost shell. Say your atom has 10 protons. So, since the number of protons is equal to the number of electrons, then your atom has 10 electrons as well. Therefore, you would have 2 electrons in your first shell and 8 electrons in your shell.

When is air stable or unstable – RMetS

Feb 1, 2021What makes air stable or unstable? It is the vertical profile of temperature, or lapse rate of the atmosphere, which determines whether an air mass is stable or not. The temperature can be measured using an electronic thermometer attached to a helium-filled weather balloon released from the ground. As it ascends, the readings are transmitted …

Nondestructive Evaluation Physics : Atomic Elements

Atom Stability. In some atoms, the binding energy is great enough to hold the nucleus together. The nucleus of this kind of atom is said to be stable.In some atoms the binding energy is not strong enough to hold the nucleus together, and the nuclei of these atoms are said to be unstable.Unstable atoms are also called radioactive actoms and they will lose neutrons and protons as they attempt to …

Reactivity: Understanding Mechanism

The larger the atom, and the further the electrons from the nucleus, the more polarizable it is. The more polarizable the atom, the more stable the anion. Within a row of the periodic table, the more electronegative an atom, the more stable the anion. Problem UM1.4. Within each group, rank the anions from most stable to least stable.

What Makes an Atom Stable? – Reference.com

An atom is stable because of a balanced nucleus that does not contain excess 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 indefinitely, while unstable atoms undergo radioactive decay. Most naturally occurring atoms are stable and do not decay.

What is the difference between stable and unstable atom?

The nucleus of this kind of atom is said to be stable. In some atoms the binding energy is not strong enough to hold the nucleus together, and the nuclei of these atoms are said to be unstable. Unstable atoms will lose neutrons and protons as they attempt to become stable.

What are stable and unstable atoms?

Similarly, what makes an atom stable or unstable? An atom is stable if the forces among the particles that makeup the nucleus are balanced. An atom is unstable (radioactive) if these forces are unbalanced; if the nucleus has an excess of internal energy. Instability of an atom’s nucleus may result from an excess of either neutrons or protons.
