Sodium has an atomic number of 11 and an atomic mass of 23. sodium has __________.
seraphim [82]

Sodium has 11 protons, therefore number of neutrons must be 23 – 11 = 12 neutrons.

Sodium has 12 neutrons.

<h3>What are neutrons?</h3>

The neutron is a subatomic particle with the symbol n that is slightly heavier than a proton and has a neutral charge (i.e., neither a positive nor a negative charge). Atoms' nuclei are made up of protons and neutrons. Protons and neutrons are both referred to as nucleons because of how similarly they function inside the nucleus and because they both have masses that are about equal to one atomic mass unit. Nuclear physics describes their characteristics and interactions.

The arrangement of electrons around an atom's hefty nucleus largely determines its chemical characteristics. The amount of protons, or atomic number, determines the charge of the nucleus, which determines the electron configuration.

Give the Unabbreviated electron configuration for barium
Shalnov [3]

Answer:

Ba: 1s² 2s²2p⁶ 3s²3p⁶ 4s²3d¹⁰4p⁶ 5s²4d¹⁰5p⁶ 6s²

Step-by-step explanation:

Step 1. Locate barium in the Periodic Table.

It's in Period 6, Group 2: Element 56 (highlighted blue in the Periodic Table below).

Step 2. Add 54 electrons to the energy levels

You add then in the order shown in the diagram below.

The complete electron configuration is:

Ba: 1s² 2s²2p⁶ 3s²3p⁶ 4s²3d¹⁰4p⁶ 5s²4d¹⁰5p⁶ 6s²

n =  2 +     8    +    8     +       18       +       18       +  2 = 56

If a red blood cell is placed in a 0.5 salt solution what will occur
photoshop1234 [79]
The red blood cell will shrink.
In salt solution, the water potential is a lot lower than the cell cytoplasm. In that way, water molecules will flow from the inside of the cell to the salt solution by osmosis. The red blood cell will loose so much water that it shrinks.
But we don't have to worry about that because this won't occur inside our body, since there is mechanism in our body that regulates the concentration of blood.
