Is bromine the same as calcium hypochlorite?
No, they are totally different
Does sodium and chlorine have the same reactivities?
NO!!! However, if you have a gas jar of chlorine, and place a pellet of sodium in it, they will react to form sodium chloride (salt)
How many protons does calcium-39 have?
The number of protons in an element will be the same regardless of the isotope or ion. To have a different number of protons would change what type of element it is. So, it is not necessary to say "how many protons does calcium-41 have?" because it is the same as saying "how many protons does calcium have?" The answer is the same in any case, the same as the atomic number, 20.
A sample of calcium contains calcium -40 calcium -44 calcium -42 calcium -48 calcium -43 and calcium -46 atoms Explain why these atoms can have different mass numbers bu the must have the same atomic?
They have different masses because the number of neutrons varie. All these are called "isotopes". Each neutron weighs a certain amount, and with more or less neutrons, the mass changes
Which element has 56 protons in its nucleus?
Barium. Atomic number 56 The reason for this is because Barium has 56 protons and the protons determin the atomic number (56).Also, that would be the same number of electrons. I hope this helped you :]
Do calcium and barium have the same reactivities?
No, they do not.
Are barium magnesium potassium and calcium all in the same group?
No. Barium and magnesium and calcium are in group 2A but potassium is in group 1A.
What is the reaction of calcium and barium?
Yes they are both alkaline earth metals in the same group on the periodic table
What raction do you get when you mix calcium nitrate and barium nitrate?
There will be no reaction because they have the same anions i.e. nitrate
Why is calcium and barium are shown in the same vertical column?
because they are both alkaline earth metals i think
Does Ba and Ca belong to the same group in the periodic table?
Yes, Calcium and Barium are both Alkaline Earth Metals.
What element have chemical properties similar to magnesium?
Beryllium, Calcium or any other element within the same family or group (vertical column on the periodic table)
Is magnesium hydroxide stronger than barium hydroxide?
No, each soluble hydroxide (sodium, potassium, magnesium, calcium, barium etc.) are as strong as all of the SAME kind of hydroxide anions (OH-).Only the solubility differences determine the concentration of OH- ions, but their 'strength' is ALL the SAME.Really hydroxide is the strongest base in water solution.Sodium, potassium, magnesium, calcium and barium hydroxides are actually (basic) SALTS of the same hydroxide anions! The cations are all neutral in water.
What is the same group of periodic table as magnesium?
Magnesium is present in group 2 of periodic table which also contains Beryllium, Calcium, Strontium, Barium and Radiium.
Is bromine the same as calcium hypochlorite?
No, they are totally different
Why are the elements listed in the same column of the periodic table?
because they have the same number of valence electrons and hence have similar properties and reactivities.
How is are the configurations of calcium and a calcium ion similar?
They are the same in that they have the same number of protons and neutrons. However, the number of electrons is different. The calcium 2+ ion has two less electrons than the normal calcium atom.
