Which of these is molecule H20 CA NA MG?
H2O (water) is a compound molecule. Ca, Na, Mg are elemental metals. NB When writing elemental symbols;- Single letter symbols are always a CAPITAL letter e.g. 'O' oxygen. Double letter symbols are always written as , first letter is a capital letter and the second letter is lower/small case. e.g. 'Ca'( Calcium). Na(Sodium) , & Mg (Magnesium). NOT as given with all capital letters.
What pair of elements has the most similar chemical properties?
The pair of elements with the most similar chemical properties are lithium (Li) and sodium (Na). They belong to the same group in the periodic table (Group 1) and exhibit similar reactivity and chemical behavior due to having one valence electron.
What the atomic number of F plus the atomic number of Na equals equals the atomic number of this element?
At No(F) + At No(Na) = 20.At No of Calcium = 20.
S na cl mg witch one is largest?
Magnesium (Mg) is the largest atom among sulfur (S), sodium (Na), chlorine (Cl), and magnesium (Mg). This is because the size of an atom increases as you move down a group in the periodic table. Magnesium is located below the other elements in the periodic table, making it the largest atom among these options.
What most likely product is formed from the reaction between calcium carbonate and sodium metal?
The reaction between calcium carbonate and sodium metal would likely produce calcium oxide, sodium oxide, and carbon. The calcium oxide and sodium oxide would be the main products, with carbon formation as a byproduct.
Which has the larger radius Na or Mg?
Mg has a larger atomic radius than Na. This is because atomic radius generally increases as you move down a group in the periodic table, and Mg is below Na in the same group. Additionally, Mg has more energy levels and electrons compared to Na, contributing to its larger atomic radius.
What are the symbols for sodium potassium calcium magnesium chloride bicarbonate and phosphate?
Sodium, Na. Potassium, K. Calcium, Ca. Magnesium, Mg. Chlorine, Cl. Bicarbonate should be CO2. Phosphorus, P.

Which of the following elements would be the most different from magnesium (Mg)?
Na
What element has the same chemical properties as neon?
Na (sodium) (2,8,1) if Na lose the outermost electron,it will be Na+ (2,8) like Ne (neon) (2,8) and Mg (magnesium) (2,8,2) if Mg lose the outer most electron, it will be Mg+2 (2,8) like Ne (2,8) and Al (aluminium) (2,8,3) if Al lose the outermost electron,it will be Al+3 (2,8) like Ne (2,8) .
Are the properties of sodium Na more like the properties of lithium or magnesium?
Na is chemically more like Li than Mg, only physically (measurements, mass) it looks more like Mg
Which pair is different from other in Li-Mg Na-K Ca-Mg B-Al?
B-Al is different from the other pairs because it consists of elements from different groups in the periodic table. Li-Mg, Na-K, and Ca-Mg are pairs of elements from the same group which exhibit similar chemical characteristics.
Why does (be) and (na) have similar properties to mg?
Both beryllium (Be) and sodium (Na) share similar properties with magnesium (Mg) due to their positions in the periodic table. Be and Mg are both alkaline earth metals in Group 2, which exhibit similar chemical behaviors, including the formation of oxides and hydroxides. Na, while in Group 1, shares some similarities with Mg in terms of reactivity and the formation of ionic compounds, as both elements readily lose electrons to form cations. Additionally, the size and charge of their ions contribute to comparable physical and chemical properties within their respective groups.
What are the predominant ions in seawater?
The most predominant ions in seawater are Na+,Mg+,I-,cl-.
What two most abundant components dissolve in seawater?
Chlorides salts of Na, Mg, Ca.
What pair of elements has the most similar chemical properties?
The pair of elements with the most similar chemical properties are lithium (Li) and sodium (Na). They belong to the same group in the periodic table (Group 1) and exhibit similar reactivity and chemical behavior due to having one valence electron.
What is the main cation in kidneys?
K+ potassium, Na+ sodium, Mg magnesium, H hydrogen, Ca calcium source: The Human Body in Health & Disease fifth edition
