What determines chemical properties of atoms?
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.
What determines the chemical properties of an atom quizlet?
The chemical properties of an element, are determined by the number of protons in the nucleus. This number of protons is called the atomic number. The mass of the atom, its atomic mass, depends upon the sum of the number of protons and the number of neutrons present in the nucleus.
What do chemical properties depend on?
The chemical properties depend on the number of the electrons and the configuration of the valence electrons of that element.
Which property determines the chemical reactivity of an element?
The number of electrons in the outermost shell of an atom determines its reactivity.
What determines similarities in chemical behavior of the atom?
When an atom is generally electrically neutral, the atomic number will equal the number of electrons in the atom, which can be found around the core. These electrons mainly determine the chemical behaviour of an atom.
What determines the chemical behavior of a substance?
The chemical behavior of atoms is determined by the number and the configuration of the electrons in the atom.
How does an atom react chemically depends?
How an atom reacts chemically depends on how willing it is to share electrons with others.
What contributes to the chemical properties of an element?
The chemical properties of an element are due to the distribution of electrons around the atom's nucleus, particularly the outer, or valence, electrons; it is these electrons that are involved in chemical reactions.
What does the chemical nature of an atom depend on?
the chemical properties of an element depend very heavily on the number of electrons the atoms of this element have in their outermost energy level.
Which part of the atom determines how the atom behaves chemically and its reactivity?
Elements are made of atoms, and the structure of the atom determines how it will behave when interacting with other chemicals. The key in determining how an atom will behave in different environments lies in the arrangement of electrons within the atom.
What determines the chemical reactivity of elements?
Chemical reactivity of the elements This is usually determined by how easily electrons can be removed (ionization energy) and how badly they want to take other atom's electrons (electronegativity) because it is the transfer/interaction of electrons that is the basis of chemical reactions.
What determines the chemical and electrical properties of an atom?
A neutral atom has an equal number of protons and electrons so that the positive and negative charges exactly balance. Since it is the electrons that determine how one atom interacts with another, in the end it is the number of protons in the nucleus that determines the chemical properties of an atom.
How does electron configuration determine chemical properties?
This allows us to determine which orbitals are occupied by electrons in each atom. The specific arrangement of electrons in orbitals of an atom determines many of the chemical properties of that atom.
What part of the atom determines the chemical properties or reactivity?
The number of protons in the nucleus determines which element it is. However, the number of electrons in the outer shell, i.e. the number of valence electrons, determines the chemical reactions that the element can participate in.
How do you know which atoms are more reactive?
The primary difference between metals is the ease with which they undergo chemical reactions. The elements toward the bottom left corner of the periodic table are the metals that are the most active in the sense of being the most reactive. Lithium, sodium, and potassium all react with water, for example.
What determines the identity of an element?
Correct answer: The identity of an element is determined by the number of protons. One cannot alter the number of protons without altering the identity of the element. By adding a proton, the atomic number increases by one and the element identity changes. Number of neutrons can be altered to create isotopes.
What determines the chemical and electrical properties of an atom quizlet?
Valence electrons are the electrons on the outmost level (orbital) of the atom and determine the chemical properties of the atom such as reactivity.
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.
Which part of an atom determines its chemical behaviour?
The number of protons in the nucleus determines which element it is. However, the number of electrons in the outer shell, i.e. the number of valence electrons, determines the chemical reactions that the element can participate in.
What determines chemical reactivity?
The number of electrons in the outermost shell of an atom determines its reactivity. Noble gases have low reactivity because they have full electron shells. Halogens are highly reactive because they readily gain an electron to fill their outermost shell.
What is the most important thing in determining the identity of an atom?
1 Answer. The proton determines the identity of an element.
What determines what type of element an atom will be?
The number of protons in the nucleus determines which element an atom is, while the number of electrons surrounding the nucleus determines which kind of reactions the atom will undergo.
Why do valence electrons determine chemical properties?
The number of valence electrons in atoms may cause them to be unreactive or highly reactive. For those atoms that are reactive, the number of valence electrons also determines whether they tend to give up or gain electrons in chemical reactions. Metals, which easily give up electrons, can conduct electricity.
What determines the chemical reactivity of element answer in one sentence?
Ans: The chemical reactivity of an element is determined by the number of valence electrons in it and the shell number of the valence shell.
How do electrons determine the chemical behavior of an atom?
Electrons located in the outermost shell of the electron cloud are called “valence electrons” and have the highest energy. Valence electrons determine the chemical properties of an element, or how the valence electrons of one element are shared or traded with valence electrons of other elements to create new molecules.
Which of the following has influence on the chemical properties of an element?
The properties of an element are determined largely by the electrons in its outermost or valence shell. Valence electrons interact with other atoms and take part in all chemical reactions, while inner shell electrons have little influence on the properties of elements.
What causes chemical reactivity?
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.
What is reactivity Chemical property?
Reactivity. Reactivity is the ability of matter to combine chemically with other substances. Some kinds of matter are extremely reactive; others are extremely unreactive. For example, potassium is very reactive, even with water.
Why atoms of most of the elements are chemically reactive?
The atoms of elements other than noble gases are unstable because: They have unstable electronic configuration, i.e. their outermost shell is incomplete. They can lose, gain or share electrons and are chemically reactive.
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.
