Does carbon have a larger atomic radius?
Comparing carbon (C) with an atomic number of 6 and fluorine (F) with an atomic number of 9, we can tell that, based on atomic radius trends, a carbon atom will have a larger radius than a fluorine atom since the three additional protons the fluorine has will pull its electrons closer to the nucleus and shrink the …
Which element has the largest atomic radius list?
francium
Does carbon have a smaller atomic radius than silicon?
Size. As expected silicon is larger than carbon due to the presence of a second shell: i.e., C = 1s2 2s2 2p2 while Si = 1s2 2s2 2p6 3s2 3p2. Atomic, covalent, and van der Waals radii of carbon and silicon.
What has the smallest atomic radius?
Helium
Is F bigger than Ne?
Which of these elements (F, Ne, or O) has the smallest atomic radii? – Quora. The answer is Ne. These 3 elements belong to the same period (row) with Ne having 1 more proton ( and electron) than F, which itself has one more proton ( and electron) than O.
Is Br or Br bigger?
Br – will have the largest atomic size because Br- has one extra electron in its valence shell which due to its unbalanced negative charge will be repelled and hence the atomic radius of Br- will increase.
Is Cl or Br bigger?
As Br is smaller than Cl; therefore, Br- have a smaller ionization energy than Cl-. In short, since the outermost electron in bromine is farther from the nucleus than the outermost electron in chloride, it takes less energy to remove the outermost electron in bromide.
What is smaller F or Ne?
Question: QUESTION 1 Why does Ne have a smaller radius than F? Ne has its valence electrons in a higher energy level than F. Fhas more protons in its nucleus than Ne. Ne has more mass than F making it larger.
Why NE is bigger than F?
(i) The size of Neon is bigger compared to fluorine because the outer shell of neon is complete(octet). Hence the size of Neon is greater than fluorine. (ii) Since atomic number of magnesium is more than sodium but the numbers of shells are same, the nuclear pull is more in case of Mg atom.
Which is bigger NE or Na+?
Since Na+ has a higher effective nuclear charge, there is a greater force of attraction between the protons in the nucleus and the valence electrons of Na+, so Na+ is smaller than Ne.
Which is bigger F or F?
More the atomic number size becomes larger. So F- is larger in size.
Which is smaller in size Li or F?
In your case, lithium has an atomic number equal to 3 and fluorine an atomic number equal to 9 . So fluorine has more protons in its nucleus. Keep this in mind. As a result, the atomic size of fluorine will be smaller than that of lithium, or, in other words, lithium will have larger atomic radius than fluorine.
Is O2 bigger than F?
Similarly, O2- will be larger than F- as both have 10 electrons but Z=8 for oxygen and Z=9 for fluorine.
Is K or K+ larger?
When at neutral, the potassium ion in the form of K has an electronic configuration of: The K+ ion has its outermost electrons on the third energy level now and is size is smaller than that of K ion. Hence, K is larger than K+.
Why is K+ more stable than k2+?
Answer: Atomic number of k = 19, We see that, Pottasium(k) has 1 electron in it’s outermost shell, So k+ will have, 8 outermost electrons, According to Octet rule, K+ will be more stable !.
What is the highest energy level for K?
Potassium, K , is located in period 4, group 1 of the periodic table, which means that it has one electron on its highest energy level. The size of a potassium atom is determined by how far that solitary electron that resides on the highest energy level, i.e on the fourth energy level, is from the nucleus.
Which is smaller S or S 2?
(ii) Explain why the radius of the S2- ion is larger than the radius of the S atom. The nuclear charge is the same for both species, but the eight valence electrons in the sulfide ion experience a greater amount of electron-electron repulsion than do the six valence electrons in the neutral sulfur atom.
Which is smaller Na+ or Mg2+?
Answer. Deduce which of Na+ and Mg2+ is thesmaller ion. mg2+ would be the smaller ion this isbecause each ion has the same number of electrons however mg2+ has a greater number of protons and therefore is more charge dense and the outer electrons feel a greater pull from the nucleus.
Why is CA bigger than Ca2+?
Ca atom will be larger than Ca2+ because cations are smaller than their parent atom. The Ca2+ cation is larger than the Mg2+ cation since the calcium cation has one more complete level than the magnesium cation.
