Why group 18 noble gases have positive electron affinity values?
Group 18 noble gases typically have positive electron affinity values because they possess a complete outer electron shell, making them energetically stable and less inclined to attract additional electrons. However, when an electron is added to a noble gas, it can lead to slight destabilization due to electron-electron repulsion in the resulting anion. As a result, the process of adding an electron is often endothermic, resulting in positive electron affinity values for these elements.
What is the change in energy if the electron having -1.3610-19 J now drops to ground state?
The ground state energy of an electron is -2.179 x 10^-18 J. The change in energy would be: final energy - initial energy, therefore: (-2.179 x 10^-18 J) - (-1.361 x 10^-19 J) = -2.043 x 10^-18 J The change in energy is -2.043 x 10^-18 J.
What is the difference in reactivity between elements in family 1 and elements in family 18?
Elements in family 1 (alkali metals) are highly reactive, readily losing electrons to form cations with a +1 charge. Elements in family 18 (noble gases) are inert and have very low reactivity because they have a full outer electron shell, making them stable and unlikely to form chemical bonds.
Which family has the correct electron configuration to be stable?
The family of 'noble' (= inert) gasses in group (column) 18 of the periodic table. Their valence shell is completely filled up with s2 and p6 electrons.
How many electron orbital shells does francium have?
Francium has seven electron shells; electrons per shell: 2, 8, 18, 32, 18, 8, 1.

How many electrons in the electron cloud does argon have?
Argon has 18 electrons in its electron cloud.
What is silver's electron pattern?
Silver's electron configuration is 2, 8, 18, 18, 1.
If the photon has a frequency of 4 x 10-15 Hz how did the energy of the electron change?
4x 1015 Hz The electron lost 2.6 x 10-18 J of energy.
What family group on periodic table is xenon?
Xenon belongs to the noble gas family (group 18) on the periodic table. Noble gases are characterized by their stability and lack of reactivity due to a full valence electron shell.
What family element belongs xenon?
Xenon is a noble gas. It belongs to noble gas family or group 18 on the periodic table.
What is the rule for electron orbit or shell?
Electron shells fill in the order 2, 8, 18, 18, 32, 32

What is th charge of an electron?
The charge of an electron is .16 E-18 Coulombs.
How many electrons are in the anion of chloride?
The anion of chloride (Cl⁻) has 18 electrons, as it has gained one electron to achieve a stable electron configuration. Chloride has 17 electrons in its neutral state, but when it gains an electron, it becomes Cl⁻ with 18 electrons.
