How many atoms of Lithium and Fluorine are needed to create the total charge of zero?
To create a total charge of zero, lithium with an atomic number of 3 (Li) needs to lose one electron to form Li+ with a charge of +1. Fluorine with an atomic number of 9 (F) needs to gain one electron to form F- with a charge of -1. Therefore, one atom of lithium and one atom of fluorine are needed to create a compound with a total charge of zero.
What is an element with a -1 charge in period 2?
It would be the ion fluoride, formed when a fluorine atom gains an electron. None of the elements on the periodic table are charged in their elemental state.
What is the total charge on each of the following ions or sets one fluoride ion?
A fluoride ion (F⁻) has a total charge of -1. This is because it gains one electron, resulting in a negative charge. Thus, the total charge on a single fluoride ion is -1.
Is electron affinity of N is greater than F?
No, it is not. Electron affinity follows a trend like electronegativity and hence increases as we move from left to right across a period. So, Fluorine has the highest electron affinity among 1st period elements.
What number of valence electrons in fluoride?
To answer this question and all other questions about valence electron, you should know where the element is on the periodic table. You can see that F is the 7th group. F is fluorine, which has 7 valence electrons. Fluoride is F with a negative charge which means it has one more electron, so Fluoride has 8 valence electrons.
What is the electron configuration of Li and F?
The electron configuration of lithium (Li) is 1s2 2s1, with 3 electrons distributed in the 1s and 2s orbitals. The electron configuration of fluorine (F) is 1s2 2s2 2p5, with 9 electrons distributed in the 1s, 2s, and 2p orbitals.
How many atoms of Lithium and Fluorine are needed to create the total charge of zero?
To create a total charge of zero, lithium with an atomic number of 3 (Li) needs to lose one electron to form Li+ with a charge of +1. Fluorine with an atomic number of 9 (F) needs to gain one electron to form F- with a charge of -1. Therefore, one atom of lithium and one atom of fluorine are needed to create a compound with a total charge of zero.
The elements Li and F combine to form an ionic compound The electron configurations in this compound are the same as the electron configurations of atoms in which group?
The electron configurations of LiF will be the same as the electron configurations of atoms in Group 18 (noble gases) because Li will lose its single electron to attain a stable octet similar to the noble gases, while F will gain an electron to achieve a complete valence shell.
What is the effective nuclear charge for an electron in the outermost shell of a fluorine atom F?
The effective nuclear charge for an electron in the outermost shell of a fluorine atom (F) is approximately +7. This charge results from the balancing of the positive charge of the nucleus with the shielding effect of inner electrons.
What type of bonding occurs in LiF?
Ionic bonding occurs in LiF, where lithium (Li) transfers an electron to fluorine (F) to form Li+ and F- ions, which are then held together by electrostatic forces of attraction.
What accounts for the fact that the radius of f is smaller than the radius of li?
Increasing positive nuclear charge
Is F- an anion?
Yes, F- is an anion. It is the fluoride anion, which carries a negative charge due to the presence of an extra electron.
How does the compound LiF Violate the octet rule?
Lithium electron configuration: 1s2 2s1, or in shorthand: [He] 2s1 Thus in LiF the Li cation (Li missing one electron to get its nobel gas configuration of He) it is Li+: 1s2 2s0, or in shorthand: [He] 2s0, This ion does NOT have 8 (octet) electrons, although it has a nobel gas configuration of He: 1s2.
What elements has the longest covalent radius of Li B N F?
The element with the longest covalent radius among Li, B, N, and F is Li. This is because as you move down a group in the periodic table, the atomic radius increases due to the addition of new electron shells. The covalent radius generally follows this trend.
What charge does a bromide ion have?
Br-, like the other halogens F-, Cl-, Br-, I-. They would obtain one electron to have noble gas electron configuration. Therefore, one negative charge.
What would be the electrical charge of fluorine atom that gained an electron?
The fluorine atom, which normally has 9 protons and 9 electrons, will have a charge of -1 after gaining an electron. This is because it now has 10 negatively charged electrons and only 9 positively charged protons.
What is the ionic charge of fluoride ion?
It is a single negative charge, so the fluoride ion is denoted F-. The fluorine atom gains one electron to incur a single negative charge of -1.
