Answer:
highest first ionization energy - Br
smallest atomic size - Br
most metallic character - Na
Explanation:
Ionization energy of Br is higher than P because higher zeff value
Sodium is more metallic than calcium because it is able to loose electron more readily as compared to calcium because of higher electro positivity.
Atomic radius of Br is the smallest as its atomic radius is 114, P (115), Ca (197), Na (186)
At time t = 273.15 °C, the x-intercept occurs. According to Charles' law, an ideal gas's volume decreases as its temperature rises. At t = 273.15 °C, the graph's x-intercept, volume approaches zero.
<h3>Charles law experiment: what is it?</h3>
Describe the Charles Law experiment. Gases have a tendency to expand when heated, according to Charles' law (sometimes referred to as the law of volumes), an experimental gas law. The Kelvin temperature and the volume will be directly proportional when the pressure on a sample of the a dry gas is held constant, according to a current interpretation of Charles's law.
<h3>Which laws—Charles and Boyles—have similarities?</h3>
Boyle's law is formulated for systems with constant temperature, whereas Charles' law is formulated for systems with constant pressure.

Answer: 1.90x10²³ atoms of O
Explanation: First convert the mass of O into moles:
5.06 g O x 1 mole O / 16 g O
= 0.32 moles O
Next use Avogadro's Number to find the number of atoms of O
0.32 moles O x 6.022x10²³ atoms O / 1 mole O
= 1.90x10²³ atoms O
The neuron maintains a resting membrane potential. ... Because potassium is in high concentration inside the neuron, there is a concentration gradient attempting to force potassium out of the cell. Similar forces will attempt to move sodium ions into the neuron. so the answer is A ions
