Based on periodic trends, the most probable value for the ionic radius of K⁺ is 133 pm.

<h3>What are periodic trends?</h3>

Periodic trends are the observation which are seen in the chemical and physical elements found in the periodic table.

Periodic trends is based on the periodicity of elements.

Periodicity is the variation seen in the chemical and physical properties of the elements in the period table in a regular pattern, both down the groups and across the periods.

The periodic trends observed in metallic ions is that ionic radius of metallic ions increase down a group but decreases across a period.

Based on this periodic trend, the most likely size of the potassium ion, K⁺ is 133 pm.

In conclusion, the ionic radius of metallic ions increase down a group and decrease across a period.

adoni [48]

Answer: BF3

Explanation: boron needs 4 electron to obtain octet and Fluorine has just one. For the valence shell to be completely filled it will have to form BF4- with 4 fluorine atom surrounding it.

Why does lithium have a higher ionization energy compared to sodium?
frez [133]

Answer:

There are 11 protons in a sodium atom but only 3 in a lithium atom, so the nuclear charge is much greater. ... The only factor left is the extra distance between the outer electron and the nucleus in sodium's case. That lowers the ionization energy.

The energy in eV for light with a wavelength of 6250 angstroms is _. Note - there are 1.6 x 10-12 erg in 1 eV.
vivado [14]

Answer:

2 eV

Explanation:

The energy of a photon of light is given by the formula

E=\frac{hc}{\lambda}

where

h is the Planck constant

c is the speed of light

\lambda is the wavelength of the photon

In this problem we have:

h=6.63\cdot 10^{-34} Js

c=3.0\cdot 10^8 m/s

\lambda=6250 A = 6250\cdot 10^{-10} m is the wavelength of the photon

Therefore, the energy in Joules is

E=\frac{(6.63\cdot 10^{-34})(3.0\cdot 10^8)}{6250\cdot 10^{-10}}=3.2\cdot 10^{-19}J

We want to convert this energy into electronvolts: we know that the conversion factor is

1 eV = 1.6\cdot 10^{-19}J

Therefore,

E=\frac{3.2\cdot 10^{-19}}{1.6\cdot 10^{-19}}=2 eV

Ms. Block's students are studying chemical reactions as well as the law of conservation of matter. A classic reaction occurs whe
goblinko [34]

The answer is; C

Conservation of matter in a reaction means that the mass of matter in the products is equal to the mass of the reactants. Energy/matter cannot be created or destroyed but converted from one form to another.

An expanding balloon with the increased evolution of gas is a good visible practical sign in the experiment on the conservation of matter in the reaction. As the magnesium disappears with an increased input of hydrochloric acid, the balloon gets bigger showing that more hydrogen is evolved from the reaction;

2HCL + Mg  MgCl2 + H2
