Why does beryllium and helium have the same valence electrons but not the same chemical properties?
Wiki User
∙ 11y ago
Helium (He) and Be2+ ion (not beryllium element) have the same number of valence electrons (two). But their properties are different as they differ in the number of protons (2 for helium, 4 for beryllium) and hence they differ in ther properties.

What is an electron called in the outermost energy level?
They are called valence electrons, and they are responsible for an atom's chemical properties. During a chemical reaction, the valence electrons are the only part of an atom that participates.
What element can be combined with beryllium?

What is beryllium number of valence electrons?
The beryllium atom has 4 electrons and the valence is 2.
How many valence electrons does a beryllium?
Beryllium has two valence electrons.
Which subatomic determines the atoms chemical properties and why?
Valence shell electrons or valence electrons determine the chemical properties of an atom...
Are atom properties determined by the size of the valence electrons?
Valence electrons are very important for the chemical properties of chemical elements; but all electrons have identical sizes.
How many valence electrons Be have?
Beryllium has two valence electrons.
What does the group number help tell you in columns?
Group number describes the number of valence electrons. It helps in estimating chemical properties of that element.For example-group-1 elements have 1 valence electronThe group number of an element is equal to the number of valence electrons. The number of valence electrons is responsible for the chemical properties. So the chemical properties of the element can be determined by the group number.
How many valence electrons does Be have?
