Compare and contrast
Chemical
elements, or simply called elements, are chemicals that can not be subdivided
into smaller substances, or can not be converted into other chemicals using
ordinary chemical methods. The element is a substance containing only one
atomic type.
Compare and contrast Sodium between Magnesium
1. Sodium (Na)
Sodium
is a chemical element in the periodic table having Na symbols and atomic number
11. Sodium is a soft, silvery, and waxy reactive metal, which belongs to alkali
metals which are widely present in natural compounds (especially halite). He is
very reactive, the flame is yellow, oxidizes in air, and reacts strongly with
water, so it must be stored in oil. Because it is so reactive, sodium is almost
never found in pure form.
Like
other alkali metals, sodium is a soft, light, silvery reactive element, which
never takes the form of a pure element in nature. Sodium floats in water,
decomposing it into hydrogen gas and hydroxide ions. If it is crushed into a
powder, sodium will explode in water spontaneously. However, it usually does
not explode in air under temperature 388 K. Sodium also when in a state bound
to OH-ion will form a strong base that is NaOH.
2. Magnesium (Mg)
Magnesium
is a chemical element in the periodic table that has the symbol Mg and atomic
number 12 and the atomic weight of 24.31. Magnesium lies classified IIA and has
a degree of oxidation 2. Magneisum also has a white flame color. Magnesium is
the eighth largest element that makes up 2% of the earth's crust, and is the
third most dissolved element in seawater. The alkaline earth metal is mainly
used as an alloy to make the aluminum-magnesium alloy often called
"magnalium" or "magnelium".

Magnesium (Mg)
Usefulness:
• Used in metal, glass, and cement production processes
• To make aircraft construction. The metal is called magnalum
• Sulfur separators from iron and steel
• Used on plates used in the printing industry
• To make the flash
• As an organic reaction catalyst
• For antacids (Mg (OH) 2), laxatives (MgSO4), refractory bricks (MgO), dental and cosmetic (MgCO3)
what is the significant different about it?
BalasHapusIf you want to distinguish it significantly we can see the periodic labeling that the two are different classes.
HapusWhat is the physical properties of the two elements above?
BalasHapussolid form and flame color
Hapuswhich one faster to reach between magnesium and sodium?
BalasHapusThe more reactive is sodium because the ionisation energy is smaller. The smaller the ionisation energy of an element the element will be easier to react.
