An atom of sodium-23 (Na-23) has a net charge of +1. Identify the number of protons, neutrons, and electrons in the atom. Then,
explain how you determined the number of each type of particle.
1 answer:
Sodium - 23 has a net charge of + 1
Atomic number = number of protons found for the element of sodium by simply looking for the element in the periodic table = 11.
Electrons = since this atom of sodium has a net charge of + 1. Use this formula to find the number of electrons.
No. Of protons - No of electrons = ion charge.
11 - X = 1
-X = 1-11
-X = -10
X = 10.
Electrons = 10. There are 10 electrons in this atom of sodium.
Neutrons = Mass number - Atomic Number = 23 - 11 = 12.
This atom of sodium -23 had 12 neutrons.

It's called Ice Wedging :)
Use the ideal gas formula-----> PV= nRT
P= 2.50 atm
V= 250 mL= 0.250 L
n= 0.100 moles
R= 0.0821 atmxL/molesxK
T= ?
T= PV/nR
T= (2.50 atm x 0.250 L) / (0.100 moles x 0.0821)= 76.1 K
