What is the maximum number of electrons that can be contained in a f subshell?

If a compound begins with a metal, it most likely is a _______ compound

Bess [88]

Answer:

Metallic compound

Explanation:

Metallic compound -

A metallic compound refers to the species having at least one metal, is known as a metallic compound.

In general a metallic compound consists of two ions, a positive ion or the cation, is is basically a metal, and,

a negative ion or an anion, which is a non - metal.

Hence, from the given statement of the question,

The correct answer is - metallic compound.

Draw the Lewis structure for BrCl3. What are the approximate bond angles about the central atom?

Korvikt [17]

Answer:

Explanation:

BrCl₃ is an interhalogen compound with a hybridization of sp³d. The approximate bond angles can be predicted from the structure (attached below). Although, the lewis structure might be predicted to be trigonal bipyramidal from the structure, it is however a T-shaped geometry because of it's two lone pairs.

Also, from the structure attached, it can be predicted that the approximate bond angles about the central atom is 120° (360 ÷ 3) since each of the three chlorine atoms is equally spaced about the central atom.

The strength of a covalent bond depends upon the size of the atoms and the bond order. In general short bonds are strong bonds.1

Oksana_A [137]

Answer:

Bond energy of (A) C≡C > (B) C=C

and, (C) C=N > (D) C-N

Explanation:

Bond energy refers to the amount of energy required to break a bond or the energy released when a bond is formed. Bond energy of a covalent bond suggests the bond strength of the chemical bond and depends on the bond length and bond order of the chemical bond.

The bond energy of a chemical bond increases with the bond order and decreases with the bond length. As, length of a bond decreases with increase in the bond order.

First pair: (A) C≡C (B) C=C

The bond order of C≡C - 3, the bond order of C=C - 2

Since the bond order: C≡C > C=C

Bond length: C≡C < C=C

Therefore, bond energy of (A) C≡C > (B) C=C

Second pair: (C) C=N (D) C-N

The bond order of C=N - 2, the bond order of C-N - 1

Since the bond order: C=N > C-N

Bond length: C=N < C-N

Therefore, bond energy of (C) C=N > (D) C-N

Which one of the following represents an acceptable set of quantum numbers for an electron in an atom? (arranged as n, 1, m, and

babymother [125]

Answer:

The correct option is A) 3, 2, -2, -1/2.

Explanation:

Quantum numbers represent different properties regarding the level, sublevel and orbital in which an electron is. There are 4 quantum numbers:

Principal quantum number (n): indicates the level of energy and gives information about the size of an orbital. It can only take positive and integer values, e. g., 1, 2, 3...
Angular quantum number (l): indicates the sublevel of energy and provides information about the shape of the orbital. Some common shapes are spherical (l=0) and polar(l=1). Shapes for bigger l are more complicated. l values depend on n values. l values can be integers up to (n-1). For example. if n = 2, l can take the values 0 and 1.
Magnetic quantum number (m): it gives information about the orientation in space of an orbital. It may take any integer value between -l and +l. For example, if l = 1, m can take values -1, 0 and 1, each one referring to an orbital p along a different axis in the space (x, y and z axes).
Spin quantum number (ms): it refers to the spin angular momentum of an electron and it can take 2 values: -1/2 or +1/2.

A) 3, 2, -2, -1/2 is correct because it follows every rule.

B) 3, 3,-4, 1/2 is wrong because if n=3, l can only be up to 2, and l from -3 to +3.

C) 3,2,0,0 is wrong because ms cannot take the value 0.

D) 3,3,3, -1/2 is wrong because if n=3, l can only be up to 2.

E) 3, 4, 6, -1/2 is wrong because if n=3, l can only be up to 2, and l from -3 to +3.
