What part of the atom determines how the atom reacts chemically with other atoms quizlet?
The distribution of electrons determines an atom's chemical properties and how they will react with other atoms.
What determines the chemical behavior of an atom quizlet?
The chemical behavior of an atom is determined by the distribution of electrons in electron shells.
What part of an atom is involved in a chemical reaction quizlet?
A nuclear reaction involves the protons and neutrons, and chemical reactions involve the electrons.
Which of the following subatomic particles determines the chemical element quizlet?
An atom that has the same number of protons but a different number of neutrons. Which subatomic particle determines the identity of an element? Protons.
What part of atoms interact in a chemical reaction?
Only the outermost parts of atoms interact (react) with each other, and those are the valence electrons. If the outermost orbital is full, the atom is stable and less likely to react with another atom.
Which part of an atom is most involved in the formation of chemical bonds?
The electrons of an atom, in particular valence electrons, are involved in chemical bonding.
What subatomic particle is responsible for determining the identity of an atom?
Protons – Protons are particles that are positively charged and are also located in the nucleus. Protons, including neutrons, give the atom mass but are not involved in chemical reactions. The number of protons that an atom has is called the atomic number and determines the identity of the atom.
What subatomic particle determines an atoms identity?
Explanation: The identity of the element is determined by the number of protons, which are positively charged, massive nuclear particles. The number of protons in a nucleus is given by Z , the atomic number.
What causes chemical reaction?
Chemical reactions involve breaking chemical bonds between reactant molecules (particles) and forming new bonds between atoms in product particles (molecules). The number of atoms before and after the chemical change is the same but the number of molecules will change.
Why do atoms take part in chemical reaction?
Atom take parts in chemical reaction in order to gain it's stable electronic configuration i.e Noble gas electronic configuration.
What determines whether atoms will form chemical bonds?
Most atoms need eight electrons to complete their outer shell. So, an atom that has two outer electrons will often form a chemical bond with an atom that lacks two electrons to be "complete."
What causes a chemical bond to form between atoms?
Bonds form when atoms share or transfer valence electrons. Valence electrons are the electrons in the outer energy level of an atom that may be involved in chemical interactions. Valence electrons are the basis of all chemical bonds.
What property of the element determines its chemical behaviour?
Hence, Valency of an element is the property that determines an element's chemical behavior.
What particle determines chemical properties?
protons The number of protons inside a nucleus must equal to the number of electrons outside of the nucleus. This number determines all the chemical properties of the atom, which governs the behaviors of all matters in our world.
What determines the chemical properties of an element?
The chemical properties of an element are determined by the number of electrons in its atom, which in turn is determined by the number of protons.
Which of the following subatomic particles determines the chemical element?
Answer and Explanation: The chemical properties of an element are determined by the subatomic particle known as a proton.
Which of the following determines the occurrence of a chemical reaction?
Some signs that a chemical change occurred include temperature increase, spontaneous change in color after mixing compounds, a marked odor after the reaction begins, formation of a precipitate in the solution and release of bubbles.
What happens to atoms in a chemical reaction?
During a chemical reaction no atoms are created or destroyed. The atoms are rearranged. This results in the formation of new substances with different properties to the starting substances.
What takes part in a chemical reaction?
Chemical reactions occur when chemical bonds between atoms are formed or broken. The substances that go into a chemical reaction are called the reactants, and the substances produced at the end of the reaction are known as the products.
What determines how an atom behaves and how many chemical bonds it forms with other atoms?
The arrangement of electrons in an atom, particularly the valence electrons, determines how an atom can interact with other atoms. The types of chemical bonds holding them together determine many of the physical properties of compounds.
What determines which atoms form chemical bonds and which don t?
So, an atom that has two outer electrons will often form a chemical bond with an atom that lacks two electrons to be "complete." For example, a sodium atom has one lone electron in its outer shell. A chlorine atom, in contrast, is short one electron to fill its outer shell.
Why do atoms form chemical bonds quizlet?
Why do atoms form chemical bonds? They want a full outer shell of electrons, so they lose, gain, or share electrons with other elements, forming compounds, until they have 8 valence electrons and become stable.
What force is responsible for chemical bonding?
A chemical bond is a lasting attraction between atoms that enables the formation of chemical compounds and may result from the electrostatic force of attraction between atoms with opposite charges, or through the sharing of electrons as in the covalent bonds.
Which setting that define the Behaviour of element?
(b) valency of an element. – The valency of an element depends upon its electronic configuration. – Hence, we can say that the chemical behaviour depends upon the valency of an element. – So, the correct answer is option (b).
What is chemical properties of elements?
A chemical property is a characteristic of a particular substance that can be observed in a chemical reaction. Some major chemical properties include flammability, toxicity, heat of combustion, pH value, rate of radioactive decay, and chemical stability.
Which of electrons determines its chemical behavior?
In this activity you have learned that the electrons in the energy sublevels with the highest number are, on the average, the farthest from the nucleus of an atom. These electrons, also known as valence electrons, determine the atom's chemical behavior.
Which electrons control the chemical behavior of an atom?
In this activity you have learned that the electrons in the energy sublevels with the highest number are, on the average, the farthest from the nucleus of an atom. These electrons, also known as valence electrons, determine the atom's chemical behavior.
Why do electrons determine the chemical behavior of an atom?
The electrons in the energy levels with the highest number are, on average, the farthest from the nucleus. Because differences in electrons located in the outermost level distinguish an atom from its nearest noble gas, these are the electrons responsible for the atom's chemical behavior.
How do you determine the type of chemical reaction?
0:537:51Types of Chemical Reactions: How to classify five basic reaction types.YouTube
What is part of all chemical reactions?
According to the modern view of chemical reactions, bonds between atoms in the reactants must be broken, and the atoms or pieces of molecules are reassembled into products by forming new bonds. Energy is absorbed to break bonds, and energy is evolved as bonds are made.
