What 3 things elements in the same group have in common?
Elements in the same group are those that are in a single vertical line from top to bottom. They have the most in common between the two directions. They share the same number of electrons in their valence subshells. As a result, they will all have the same chemical reactivity.
What are 2 elements in the same group?
Congeners refer to elements in the same group in periodic table. For example, congeners of the Group 1 elements are Li , Na and K etc.
What similarities do elements in the same group have?
The elements in the same group has similar number of valence electrons. They have identical number of electrons in their outermost shell. e.g. All the alkali metals in Group 1 have 1 valence electron, so they all tend to react the same way with other substances.
What do the elements in the same groups have in common and what does it cause them to do?
What do elements in the same group have in common? They have similar chemical properties and the same number of valence electrons.
Are characteristics and elements the same?
Characteristics: Any one of the simplest chemical substances that cannot be decomposed in a chemical reaction. Chemical elements consist of atoms which have the same number of protons.
Why do elements in the same group have similar?
Elements in the same group have similar properties because they have the same number of valence electrons in their outermost shell. Elements in the same period have different properties because the number of valence electrons in their outermost shells differ.
Why do elements in the same group have similar properties?
A vertical column in the periodic table of elements is called group. So, we can say that elements in a group have the same physical and chemical properties because their atoms have the same number of valence electrons or same valence shell electronic configuration.
What characteristics do elements in the same group have in common select all that that apply?
What is the similarities and differences of elements and compounds?
A compound contains atoms of different elements chemically combined together in a fixed ratio. An element is a pure chemical substance made of same type of atom. Compounds contain different elements in a fixed ratio arranged in a defined manner through chemical bonds. They contain only one type of molecule.
What is difference of element and compound?
Element: Pure substance consisting of one type of atom. Compound: Pure substance consisting of two or more different atoms. Mixture: Two or more different substances not chemically combined.
What does it mean if elements are in the same period?
electron shells
Elements in the same period have the same number of electron shells; moving across a period (so progressing from group to group), elements gain electrons and protons and become less metallic. This arrangement reflects the periodic recurrence of similar properties as the atomic number increases.
What two elements that belong to the same group?
Size of their atoms
What do all elements in the same group have in common?
Elements in the same group are those that are in a single vertical line from top to bottom. They have the most in common between the two directions. They share the same number of electrons in their valence subshells. As a result, they will all have the same chemical reactivity .
What do you know about elements in the same group?
Elements in the same group tend to show patterns in atomic radius, ionization energy, and electronegativity . From top to bottom in a group, the atomic radii of the elements increase. Since there are more filled energy levels, valence electrons are found farther from the nucleus.
What do elements in a group have the same number of?
Every element in a group has the same amount of electrons in their outer shell. For Example, all elements in Group 2 – Alkaline Earth Metals have 2 electrons in their outer shell. Elements in the same group also have very similar characteristics such as what they react with etc.
