Which atom is the smallest among lithium and fluorine?
The smallest atom is lithium, as it has a smaller atomic radius compared to fluorine. This is because as you move across a period on the periodic table, atomic radius decreases due to increased nuclear charge pulling the electrons closer to the nucleus.
Why do the valence electrons in nitrogen experience a greater effective nuclear charge than the valence electrons in beryllium?
The valence electrons in nitrogen are located farther from the nucleus and shielded by inner electron shells, resulting in an increased screening effect and a higher effective nuclear charge experienced by the valence electrons. In contrast, the valence electrons in beryllium are in a lower energy level closer to the nucleus, which leads to a weaker screening effect and a lower effective nuclear charge.
What is nitrogen hydrogen oxygen beryllium flouride?
Nitrogen, hydrogen, and oxygen are elements on the periodic table, with various properties and uses. Beryllium is a lightweight metal often used in nuclear applications due to its high strength and low density. Fluoride is an anion typically found in compounds like calcium fluoride or sodium fluoride, often used in dental products for strengthening teeth.
Why is the ionization energy of beryllium is higher than lithium?
Ionization energy represents the energy required to remove electrons from an atom. The first and second ionization energies are relatively small because the lectrons must be removed from the 2s orbital. For the third ionization energy the electron must be removed from the 1s orbital which has less energy than the 2s, and so requires much more energy to be removed.
Is the sodium ion larger than the fluoride ion?
Sodium ion is smaller than fluoride ion. Sodium ion and fluoride ion are isoelectronic.They have the same number of electrons. For example, Na+ and F- has 10 electrons.In any isoelectronic series we can list the members in order of increasing atomic number; therefore, nuclear charge increases as we move trhrough the series. Because the number of electrons remains constant, ionic radius decreases with increasing nuclear charge as the electrons are more strongly attracted to the nucleus.
What is the nuclear reaction for beryllium-7 into lithium-7?
beryllium 7 accepts a beta particle to convert to lithium 7 4Be7 + -1e0 = 3Li7
What nine elements have been around longer?
The nine elements that have been around longer are hydrogen, helium, and lithium, which were created during the Big Bang, followed by beryllium, boron, carbon, nitrogen, oxygen, and fluorine, which were formed in the cores of stars through nuclear fusion processes.
What happens when you combine lithium and beryllium?
When lithium and beryllium combine, they form a compound called lithium beryllide (LiBe). This compound is mainly used in nuclear reactors due to its ability to efficiently capture neutrons. It has a high melting point and is often used as a moderator or reflector in nuclear applications.
What is the nuclear decay equation for beryllium 7?
The nuclear decay equation for beryllium-7 is: Be-7 -> Li-7 + e⁻ + νe This shows that beryllium-7 decays into lithium-7, an electron, and an electron antineutrino.
Why is fluorine more electronegative than both lithium and chlorine?
Fluorine is more electronegative than lithium and chlorine because it has a greater nuclear charge and a smaller atomic size. These factors result in a stronger attraction for electrons in the fluorine atom, making it more electronegative compared to lithium and chlorine.
Which atom is the smallest among lithium and fluorine?
The smallest atom is lithium, as it has a smaller atomic radius compared to fluorine. This is because as you move across a period on the periodic table, atomic radius decreases due to increased nuclear charge pulling the electrons closer to the nucleus.

Correct increasing order of the atomic radii of O F and N?
The correct increasing order of atomic radii for oxygen (O), fluorine (F), and nitrogen (N) is F < O < N. Fluorine has the smallest atomic radius due to its higher effective nuclear charge, which pulls its electrons closer to the nucleus. Oxygen has a larger radius than fluorine, and nitrogen has the largest radius among the three due to its lower effective nuclear charge compared to oxygen and fluorine.
Why is the ionisation energy of Nitrogen higher than Beryllium?
Beryllium is a metal. It has 2 valance electrons (in the outer shell), and therefore it tends to lose those electrons in order to achieve a stable electron configuration, which in the case of beryllium is also 2 electrons, but in the inner shell. Nitrogen is a nonmetal, with 5 valence electrons, and it tends to acquire more electrons in order to reach a stable electron configuration of 8. Less energy is need to lose electrons when the result is going to be a stable electron configuration.

Beryllium is a lightweight metal often used in nuclear applications due to its high strength and low density. Fluoride is an anion typically found in compounds like calcium fluoride or sodium fluoride, often used in dental products for strengthening teeth.
What is effective nuclear charge of beryllium?
1.5
What is the nuclear charge of fluorine?
The same as its atomic number, with a positive sign: +9 for fluorine.
