What else can I help you with?
Do compounds have valence electrons?
Yes, compounds have valence electrons. Valence electrons are the outermost electrons of an atom involved in chemical bonding, and they are also involved in forming compounds by interacting with other atoms' valence electrons.
Do a family of elements share the same number of valence electrons?
Yes, elements in the same family on the periodic table share the same number of valence electrons. Valence electrons are the outermost electrons in an atom, and they determine the element's chemical properties. Elements in the same family have similar chemical properties because they have the same number of valence electrons.
How do you use the valence electrons to tell what element it is?
This only works with a periodic table in front of you. The first column has only one valence electron, while the last has a full shell (2 for Helium, 8 for the rest). However, the transition elements (the rectangle in the middle) are a bit more complex, so exclude those.
How can you tell that the beryllium atom is unstable?
You can tell that the beryllium atom is unstable because beryllium only has 2 valence electrons in its outer shell. An atom becomes stable when it has eight valence electrons, so in the case of beryllium it would have to lose those 2 electrons in its outer shell to become stable. often forming a cation with a 2+ charge.
What does the group number of A tell us about the valence electrons?
no
Does the valence of an atom tell it what it can and cannot combine?
The valence indicate the type of a possible compound.
What does the group number of the periodic table tell you about the structure of an atom?
The group number of an atom in the periodic table tells you the number of valence electrons that atom has. Valence electrons are involved in the atom's chemical reactions and determine its chemical properties. Atoms in the same group have similar chemical behaviors due to having the same number of valence electrons.
What do valance electrons tell us about atoms?
Valence electrons are the outermost electrons in an atom's electron cloud, and they determine the atom's chemical properties. The number of valence electrons influences how likely an atom is to form chemical bonds with other atoms. Elements with the same number of valence electrons tend to exhibit similar chemical behavior.
What does the number of electrons on the outershell of an atom tell us?
The valence of the element
What does it tell you about the nucleus of the carbon atom?
nucleus of carbon atom contains 6 protons and 6 neutrons.
Do compounds have valence electrons?
Yes, compounds have valence electrons. Valence electrons are the outermost electrons of an atom involved in chemical bonding, and they are also involved in forming compounds by interacting with other atoms' valence electrons.
Does the periodic table tell you how many valence electrons an atom of an element has?
simply yes
What does the group of A elements tell about valence electrons?
All elements in the same A group will have the same number of valence electrons.
What does the group number of a element tell about valence electrons?
All elements in the same A group will have the same number of valence electrons.
Does the valence shell of electrons determine how one atom bonds to another atom to make a molecule?
No, valence electrons are the electrons in the outermost energy level of an atom. A molecule is the smallest physical unit of an element or compound, consisting of one or more like atoms in an element and two or more different atoms in a compound.
What columns in periodic table tell us about the atom?
How many valence (outer shell) electrons an element has.
Does valence tell us to what extent an atom can combine?
Valence refers to the number of electrons an atom can either gain, lose, or share in order to achieve a stable electron configuration. It helps determine how an atom can combine with other atoms to form chemical bonds.
