Answer:
the answer is A
I made a chart for AP chem if you want to refer to it.
1) ₁₄Si 1s²2s²2p⁶3s²3p².
Principal quantum number (n=3) have four electrons (3s²3p²).
2) ₁₉K 1s²2s²2p⁶3s²3p⁶4s¹.
Azimuthal quantum number (l=o) have seven electrons (1s²2s²3s²4s¹).
3) ₈₀Hg [Xe] 4f¹⁴5d¹⁰6s².
Principal quantum number (n=4) have thirty-two electrons (4s²4p⁶4d¹⁰4f¹⁴).
The principal quantum number<span> is one of four </span>quantum numbers<span> which are assigned to each electron in an </span>atom<span> to describe that electron's state.</span>
The azimuthal quantum number<span> is a </span>quantum number<span> for an </span>atomic orbital<span> that determines its </span>orbital angular momentum<span> and describes the shape of the orbital. </span>
Answer:
The center of an Atom is called the Nucleus.
Explanation:
Answer: chemical property
Explanation: This is a chemical property because it was combined with carbon, another molecule acting like an element. The answer to the question is chemical property. Hope this helps!
Answer:
V = 150 mL
Explanation:
Hello!
In this case, since the molarity of a solution is computed via:
Whereas we are asked to compute the volume:
Thus, we first compute the moles in 12.0 g of NaOH as its molar mass is about 40.0 g/mol:
Thus, at first instance, the volume liters is:
Which in milliliters is:
Best regards!
