What else can I help you with?
Ions of CaFMg and iodine have electron configurations that are similar to which noble gases?
socks answer should be D
Which elements have electron configurations that end in ns 2 np 5?
The elements with the electron configurations that end in ns 2 and np 5 are halogens, group VII A elements.
Which elements have electron configurations that end in ns2np5?
The elements with electron configurations ending in ns2np5 are the halogens in Group 17 of the periodic table. This includes fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). These elements have seven valence electrons and readily gain an electron to achieve a stable octet configuration.
How does fluorine differ from iodine in the periodical table?
Fluorine is located to the left of iodine in the periodic table. Fluorine is a highly reactive nonmetal, while iodine is a less reactive nonmetal. Their chemical properties and reactivities differ due to their electron configurations and atomic sizes.
How do you write out the electron configurations of solutions?
Solutions are mixtures of one or more solutes dissolved in a solvent. They do not have electron configurations. Only atoms and ions have electron configurations.
Which elements have electron configurations that end in ns 2 and np 5?
The elements with electron configurations that end in ns 2 and np 5 are found in Group 17 of the periodic table, known as the halogens. This group includes elements such as fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).
Which elements have electron configuration that end in ns2 np5?
The elements with electron configurations ending in ns2 np5 are the halogens in group 17 of the periodic table: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).
What are the examples of elements with predictable electron configurations?
All of the representative elements (s and p block) have predictable electron configurations. However, many of the transition elements have electron configurations that are not predicted by the rules for determining electron configuration.
Does Iodine have less electron affinity than fluorine?
Yes. It's true. Chlorine has the highest electron affinity, then Fluorine, Bromine and Iodine
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.
Does iodine gain or loss electron?
Barium loses electrons to obtain a stable octet, like any other metal.
What have stable electron configurations?
any time there are as many electrons and protons and they fill each orbital optimally.
