Which two elements have the most similar chemical properties?

Chemistry
2 answers:
Sedbober [7]3 years ago

atoms are made of 3 types of sub atomic particles- protons, neutrons and electrons

from these 3 particles, electrons are responsible for participating in chemical bonds. therefore chemical properties of elements are based on the number of electrons present.

valence electrons are the number of electrons in the outermost energy shell that are involved in chemical bonds.

atoms with same number of valence electrons are grouped in to columns called groups.

therefore elements of the same group have same number of valence electrons, hence similar chemical properties.

from the options given

only Be and Mg belong to the same group they both belong to group 2 with 2 valence electrons

therefore Be and Mg have similar chemical properties

answer is

1) Be and Mg

Answer:

oxygen

Explanation:

because the 2nd shell is not complete which is suppose to be 8 and since oxygen is 8 it first shell is 2 which is complete and the second shell which is 6 is not complete because we all know that 2+6=8 but the standard shell is

3. Discuss the difference between molarity and molality, state the units of each, state the symbol for each, and give an example
dangina [55]

<span>Molality(m) or molal concentration is a measure of concentration and it refers to amount of substance in a specified amount of mass of the solvent. Used unit for molality is mol/kg which is also sometimes denoted as 1 molal. It is equal to the moles of solute (the substance being dissolved) divided by the kilograms of solvent (the substance used to dissolve).</span>

Molarity(M) or molar concentration is also a measure of concentration and represents the amount of substance per unit volume of solution(number of moles per litre of solution. Used unit for molarity is mol/L or M. A solution with a concentration of 1 mol/L is equivalent to 1 molar (1 M).

Molality is preferred when the temperature of the solution varies, because it does not depend on temperature, (neither number of moles of solute nor mass of solvent will be affected by changes of temperature), while molarity changes as temperature changes(volume of solution changes as temperature changes).
