Alkaline Earths

When they are reacted, a base and hydrogen gas is produced. This reaction is exothermic.

The maximum density in this list: radium with 5,50 g/cm3.

An atom of fluorine

A higher cation charge concentrated on the smaller cations makes it hard to pull apart ionic lattices

A./2

Calcium: 589,9 kJ/mol.

Beryllium: 899,5 kJ/mol.

Barium is used to help doctors visualize your intestines. It is given as a barium enema x-ray, and is useful in identifying problem areas, but may miss 40% of polyps. An examination with a colonoscope identifies problems with greater accuracy.

The alkali group of metals is the most active.

i think that lack of calcium makes your bones weak.

Strontium

BeCl+AgN2+H2O----->BeN2+AgCl

magnesium

Platinum is a transition metal. It is in the d block.

BeF2 is non-polar as it is (strangely) covalent in nature and as such, the molecule has a linear shape which produces a non-polar molecule.

beryllium has 4 protons. helium has 2 protons

Magnesium, Iron, Copper,sodium and potassium

beryllium has 4 protons and helium has 2 protons

Beryllium is a stable element.

Inorganic salts such as Calcium chloride, barium fluoride, magnesium iodide etc are formed.

BERYLLIUM :)

Calcium

No! Do not touch it. If you do you will get bured very badly. And will have to go to the doctor.

Beryllium arsenide, Be3As2; doubtful compound.

it keeps your teeth clean
