What two elements are most alike?

What two elements are most alike?

Elements that are in the same group of the periodic table are most likely to exhibit similar chemical and physical properties. We therefore expect that Ca and Mg should be most alike because they are in the same group (group 2A, the alkaline earth metals). Locate Na (sodium) and Br (bromine) on the periodic table.

Can two elements be alike?

No. Two atoms of the same chemical element are typically not identical. First of all, there is a range of possible states that the electrons of an atom can occupy. Two atoms of the same element can be different if their electrons are in different states.

Which 2 elements have the same characteristics?

Two elements have similiar characteristics when they belong to the same family that means that have placed in the same column of the periodic table. On the periodic table you can also find some chemical-phisic characteristics like electronegativity, density, melting point…

What do the elements in Group 2 have in common?

The property that is common to all group 2 elements is that they tend to form ionic bonds by losing electrons making these atoms positive charge. These elements are beryllium, magnesium, calcium, strontium, and radium.

What elements that have similar properties?

A modern periodic table arranges the elements in increasing order of their atomic numbers and groups atoms with similar properties in the same vertical column (Figure 2). Each box represents an element and contains its atomic number, symbol, average atomic mass, and (sometimes) name.

How are two atoms of the same element alike?

Atoms of the same element consist of the same atomic number that is number of protons or electrons and different mass number that is number of neutrons. This variation or change in the number of neutrons in an atom gives rise to different isotopes of an element. An element with different isotopes occurs in nature.

How are atoms and elements similar?

A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons. An element is a substance that is made entirely from one type of atom. All isotopes of a particular element have the same number of protons, but can have different numbers of neutrons.

What elements have the similar properties?

Elements in the same group of the periodic table have similar chemical properties. Elements can be classified as metals, metalloids, and nonmetals, or as a main-group elements, transition metals, and inner transition metals.

What pair of elements have similar properties?

For example, pairs lithium (Li) and magnesium (Mg), beryllium (Be) and aluminium (Al), boron (B) and silicon (Si), etc are exhibiting similar properties. Boron and Silicon are both semiconductors. Thus Magnesium and Lithium have similar properties.

What do group 1 and 2 have in common?

These elements are highly reactive and the reactivity of these metals increases as you go down the group. These elements also react vigorously with water. Both Group one and two metals have similar patterns.

Which is two elements have the most similar chemical properties?

Which two elements have the most similar chemical properties? 1 (1) beryllium and magnesium. 2 (2) hydrogen and helium. 3 (3) phosphorus and sulfur (4) potassium and strontium. Both elements appear on the same group (II),and therefore have… More

How are elements in the same group similar?

Elements in the same groups (columns) have very similar chemical properties. This is due to that fact that elements in the same group have the same number of valence electrons (electrons in the outermost shell). Let’s try an example. Which two elements have the most similar chemical properties?

What are two elements that have properties like beryllium?

Probably the two elements with properties most like beryllium are magnesium and aluminium.

Are there any elements that react with water?

For instance, sodium, potassium, lithium, rubidium, and caesium all react exothermally with water, while copper, silver, and gold are all good conductors of electricity. Elements in the same group in the periodic table have similar chemical properties.
