What else can I help you with?
What do you call elements in a row on the periodic table?
Elements in a row on the periodic table are called periods. They represent the number of electron shells an element's atoms have. Each period corresponds to the energy level of the electrons in an element's atoms.
What is the different about the valence electrons for all elements in a group?
Valence electrons for elements in the same group are the same because they are located in the outermost energy level of an atom. This common number of valence electrons is what gives elements within a group similar chemical properties.
Is metallic elements more likely to lose electron than nonmetallic elements?
Yes, metallic elements are more likely to lose electrons than nonmetallic elements. This is because metallic elements have fewer valence electrons and their atomic structure makes it easier for them to lose electrons to achieve a stable electron configuration. Nonmetallic elements typically gain electrons to achieve a stable electron configuration.
What does the group number of A elements (in the AB numbering system) tell about valence electrons?
The group number of A elements in the AB numbering system tells you the number of valence electrons that element has. Elements in the same group have the same number of valence electrons, which determines their chemical properties.
How the d-block group number relte to the number of outer s and d electrons?
The d-block elements have two electrons in their outermost s sublevels. The group 3 elements have one d electron in their outermost d sublevel, the group 4 elements have two d electrons, adding one additional d electron with each subsequent group until group 12 in which the elements have ten d electrons.
What is the most important factor in an elements place in the periodic table?
Its elemental weight
What is the number of electrons in outer shell called?
The number of electrons in the outermost shell is called the valence electrons. These electrons determine the chemical properties of an element and how it interacts with other elements.
When determining an elements identity what is the most important subatomic part to examine?
The number of protons in the nucleus is the most important subatomic part to examine when determining an element's identity. This is because the number of protons determines the element's atomic number, which is unique to each element.
What determines a elements chemical properties?
An element's chemical properties are primarily determined by the number of protons and electrons in its atoms. These properties include reactivity, bonding behavior, and physical characteristics. The arrangement of electrons in the outermost energy level (valence electrons) is also important in determining how an element will interact with other elements.
How do you visually represent ionic bonds?
Show the sharing of electrons between the two elements.
What does the blocks represent?
For the elements in the s-block, the valence electrons are filled in the s orbital.
Where are the valence electrons found in an atom and why are these particular electrons most important to the chemical properties of the atom?
Valence electrons are found in the outermost energy level of an atom. These electrons are important because they are involved in forming chemical bonds with other atoms, determining the atom's reactivity, ability to combine with other elements, and overall chemical behavior.
Which subatomic particle plays the greatest part in determining the propertiesof an element?
Electrons play the greatest part in determining the properties of an element. The number of electrons in the outermost energy level (valence electrons) determines an element's chemical behavior, such as its reactivity and ability to form bonds with other elements.
In an periodic table dots around an elements symbol indicate the number of valence electrons in an atom?
Yes, that is correct. The number of dots around an element's symbol in the periodic table corresponds to the number of valence electrons that element has. Valence electrons are the outermost electrons in an atom and play a significant role in determining an element's chemical properties.
How many electrons represent a complete outermost energy level for elements heavier than boron?
14
Why do elements as a family or group share similar properties?
Elements in the same group have the same number of valence electrons, which determines their chemical properties. This leads to similarities in reactivity and chemical behavior among elements in the same group.
What does the column in the periodic table stand for?
they represent elements. the elements in a given column (or group) have the same number of valence electrons and hence similar properties.
