How does the number of separate electrons shown for the group 1 metals compared to the number of atoms?
In group 1 metals, such as lithium, sodium, and potassium, each atom has one valence electron in its outermost shell. Therefore, for every atom of a group 1 metal, there is one separate electron associated with it. This means that the number of separate electrons is equal to the number of atoms in a sample of these metals. Thus, if you have, for example, five atoms of sodium, you would also have five separate valence electrons.

What is the difference of number of valence electrons and periodic table group number?
Valence electrons and group number for metal are same. For non-metals, valence electrons are equal to group number-10.
Do thicker metals have more electrons?
Thicker metals do not necessarily have more electrons. The number of electrons in a metal is determined by its atomic structure, which remains the same regardless of the metal's thickness. However, thicker metals may have a higher density of electrons due to a larger number of atoms present.
Shortcut for finding number of valence electrons an atom has?
For main group elements, the number of valence electrons is equal to the group number. For transition metals and inner transition metals, the number of valence electrons can be determined by looking at the group number (column number) in the periodic table and adjusting accordingly for the specific element.
Is an ion a class on the periodic table?
No. The three classes of the periodic table are metals, semi metals and non metals. Ions are atoms that are missing one or more electrons, resulting in a net charge. This is because the number of protons (+) no longer equals the number of electrons (-).
Do transition have higher melting point than alkaline and alkali metals?
Yes, transition metals generally have higher melting points compared to alkaline and alkali metals. This is because transition metals have a greater number of valence electrons and a stronger metallic bond, which requires more energy to break and transition from solid to liquid. In contrast, alkaline and alkali metals have fewer valence electrons and weaker metallic bonds, resulting in lower melting points.
Compared with nonmetals the number of valence electrons in metals are generally what?
greater conductivity and higher melting points than nonmetals. Or D, because your looking at the STAR review packet. :)
What is the number of valence electrons in alkaline earth metals?
Alkaline earth metals have 2 valence electrons.
What are Ions that are deficient in electrons?
Ions that are deficient in electrons are called cations. Cations have a positive charge due to the lack of electrons compared to the number of protons in the nucleus. These ions are typically formed by metals losing electrons during chemical reactions.
Why metals good electrical conductors?
In their regular (lattice) structure, metals have a sea of free electrons. This allows the electrons to flow through the metal at will and this is what makes metals good conductors of electricity (and heat).Their mobile electrons
When metals lose electrons what do they form?
Metals lose electrons and form cations to get a full octet.
What is the number of valence electrons for Alkali Earth Metals?
Alkali Earth metals have a single valence electron, and are found in the first group.
What is the difference of number of valence electrons and periodic table group number?
Valence electrons and group number for metal are same. For non-metals, valence electrons are equal to group number-10.
How many electrons does rare earth metals have?
Rare earth metals have a varying number of electrons, as it depends on the specific element within the group. The rare earth metals are a group of elements in the lanthanide series of the periodic table. They typically have between 57 to 71 electrons based on their atomic number.
What is the number of valence electrons for group 2 elements?
Group 2 metals have 2 valence electrons. In fact, the number of valence electrons of elements can be deduced from the group number (e.g. group VII elements have 7 valence electrons).
Do thicker metals have more electrons?
Thicker metals do not necessarily have more electrons. The number of electrons in a metal is determined by its atomic structure, which remains the same regardless of the metal's thickness. However, thicker metals may have a higher density of electrons due to a larger number of atoms present.
