Explanation:
The answer is 4 (four).
Hope this helps!!! :)
Answer:
The correct option is;
(B) 1 s², 2s², 2p⁶, 3s², 3p³
Explanation:
The electron configuration is the outline of the electron arrangement about a nucleus
In the systemic pattern of electron arrangement within an atom, there are, s, p, d, f orbitals
The maximum number of electrons in an s, p and d orbital = 2, 6, and 10 respectively
Based on Aufbau's principle the electrons are arranged based on the order of their energy level
The charge is presented by the number of electrons in the outermost shell, an element able to form an ion of charge of -3 will gain 3 electrons to complete its outermost shell
Among the options given, option B is the only option that has the capacity to take the electrons to complete the number of electrons in the p orbital outermost shell to 6 from 3, that is 3p³ + 3e⁻→ 3p⁶.
Answer:
Correct answer is (C) Silicon has the ability to form a partial double bond with a halogen through the overlap of its d-orbital with a p-orbital of the halogen
You question did not complete as the options are missing. See the options below;
A) The larger silicon atoms permit better overlap of its atomic orbitals with those of the halogens than the smaller carbons atoms do.
B) The large electronegativity difference between silicon and the halogens makes their bonds stronger than those of carbon.
C) Silicon has the ability to form a partial double bond with a halogen through the overlap of its d-orbital with a p-orbital of the halogen.
D) Silicon has a larger effective nuclear charge than carbon which allows it to bond more strongly to the more negative halogens than carbon.
E) Carbon-halogen bonds are unusually weak
Explanation:
Silicon reacts vigorously with halogens to form siliconhalides. The d subshell has 5 orbitals and halogen carries seven valence electronics with 5 in its p-orbital. When they react, they form stronger bonding than carbonhalide
Answer:
methanol is a carbon compound which is formed by covalent bonding .
