What Elements like calcium located toward the top of a group have a high attraction for their valence electrons because the have a?
Elements like calcium located toward the top of a group have a high attraction for their valence electrons because they have a relatively low atomic size and therefore a stronger effective nuclear charge. This results in a greater tendency for these elements to attract and hold onto their valence electrons.
Why are valence electrons easier to remove from an atom than core electrons?
Valence electrons are further away from the nucleus and experience less attraction to the positively charged protons in the nucleus compared to core electrons. This makes valence electrons easier to remove from an atom. Core electrons are located closer to the nucleus and are more strongly attracted to the nucleus, requiring more energy to remove them from the atom.
Elements like francium located at the bottom of a group have a lower attraction for their valence electrons because they have a?
higher atomic number and larger atomic size, causing their valence electrons to be farther away from the nucleus, resulting in a weaker attraction. Additionally, the shielding effect of inner electron shells reduces the effective nuclear charge felt by the valence electrons, further decreasing the attraction.
Where are innermost electrons located?
Innermost electrons are located closer to the nucleus of an atom, in energy levels closest to the nucleus. These electrons have lower energy and are usually referred to as core electrons.
Where are the valence electrons in an atom?
In the outermost shell that has electrons in it, those are called the valence electrons. For example carbon has 6 electrons, but only 4 are valence electrons because there are 2 in the shell in between it and the center of the element and 4 on the outside shell.
Is Elements like francium located at the bottom of a group have a lower attraction for their valence electrons because they have a .?
Elements like francium, located at the bottom of a group in the periodic table, have a lower attraction for their valence electrons due to increased shielding and greater atomic radius. As additional electron shells are added, the inner electrons repel the outermost electrons, reducing the effective nuclear charge felt by these valence electrons. Consequently, this diminished attraction makes it easier for these elements to lose their valence electrons, resulting in higher reactivity.
What Elements like calcium located toward the top of a group have a high attraction for their valence electrons because the have a?
Elements like calcium located toward the top of a group have a high attraction for their valence electrons because they have a relatively low atomic size and therefore a stronger effective nuclear charge. This results in a greater tendency for these elements to attract and hold onto their valence electrons.
How electrons work?
Electrons have negative charges, and unlike neutrons and protons are located on the outside of the atom. They are generally located in electron clouds around the atom, and stay there because of their attraction to protons that are in the nucleus of the atom.
Elements, like calcium, located toward the top of a group have a high attraction for their valence electrons because they have a _?
small atomic radius.
Why the elements located toward the bottom of a group have a lower attraction for their valence electrons?
Elements located toward the bottom of a group have a lower attraction for their valence electrons primarily due to increased atomic size and the shielding effect. As you move down a group, additional electron shells are added, which increases the distance between the nucleus and the valence electrons. This greater distance, along with the presence of inner electrons that shield the positive charge of the nucleus, reduces the effective nuclear charge experienced by the valence electrons, leading to weaker attraction.
Why are valence electrons easier to remove from an atom than core electrons?
Valence electrons are further away from the nucleus and experience less attraction to the positively charged protons in the nucleus compared to core electrons. This makes valence electrons easier to remove from an atom. Core electrons are located closer to the nucleus and are more strongly attracted to the nucleus, requiring more energy to remove them from the atom.
Why do Elements located toward the bottom of a group have a lower attraction for their valence electrons?
Elements located toward the bottom of a group have a lower attraction for their valence electrons primarily due to increased atomic size and electron shielding. As you move down a group, additional electron shells are added, which increases the distance between the nucleus and the valence electrons. This greater distance, coupled with increased electron shielding from inner electrons, reduces the effective nuclear charge felt by the valence electrons, leading to weaker attraction. Consequently, these elements are more likely to lose their valence electrons in chemical reactions.
Holds Electron and prontons together?
The electromagnetic force holds electrons and protons together in an atom. Protons have a positive charge and electrons have a negative charge, and opposite charges attract each other. This force of attraction keeps the electrons orbiting around the nucleus where the protons are located.
Are valance electrons located near the nucleus?
Valance electrons are not located near the nucleus. These electrons are in fact located the furthest away from the nucleus compared to other electrons.

Why is it important that the electrons and protons are attracted to each other?
It is important for electrons and protons to be attracted to each other because this electrostatic force holds the atom together. Protons are positively charged and located in the nucleus, while electrons are negatively charged and orbit the nucleus. The attraction between them creates a stable structure, allowing atoms to form bonds and create matter.
How many electrons are in mercury and where are they located?
There are 69 electrons.
