What are 2 properties of boron?
Boron forms electron poor hydrides that can exist in many different shapes and formulas because of the hydrogen bridges it can form.
Do zinc and magnesium have similar ions?
Zn and Ca both have double positive (2+) ions: Zn2+ and Ca2+ but other properties are different.
What two groups of the periodic table are most similar in chemical properties?
Group 1 and group 2 or Group 16 and group 17
What properties do elements in the same family of a periodic table share?
Well, for one, they have the same amount of electrons in the outmost shell: Group 1 has 1, Group 2 has 2 etc... They all share similar chemical properties, for example Group 6 (?) S and Se both are acidic oxides.
Which element has chemical properties most similar to those of the element calcium?
atoms in the same group are similar. calcium is in group 2, so it's similar to Be, Mg, Sr, Ba and Ra. Most similar would be Mg or Sr, which are right above and below. all group 2 atoms share a similar electron configuration
Are similar shapes always congruent?
Yes because to be similar the shapes need to have the same ratio of sides and similar angles. To be congruent the shapes have to be the same shape and size, so 2 congruent shapes will always be similar.
What Shape has no straight lines but has 2 rotation symmetry?

How are the polygons in problems 1 and 2 similar how are different?
I think that 1 2 can not be similar cause there different shapes
How can you tell both shapes are similar?
to prove two triangles are similar, get 2 angles congruent
How is polygons similar?
They are closed 2-D shapes with straight sides.
When 2 shapes are similar and have a scale factor of 1 what are they called?
They are congruent.
Why is it that if a shape is congruent its similar?
Congruency means that the given 2 figures are exactly same in shape and size. Thus all corresponding angles will also be the same.Similarity of shapes means that the 2 given shapes are same in shape but the measures of corresponding sides may not be the same. Since the shapes are the same, the corresponding angles are also same.If 2 shapes are congruent, they have equal corresponding angles. The equal angles satisfy the condition for the shapes being similar. Hence congruent shapes are similar as well.
Which 2 elements would have similar properties?
chicken and duck
What shapes can 2 triangles make?
Trapezoid.
I need to decompose and transform a pentagon into 2 shapes. What 2 shapes can make up a pentagon?
A quadrilateral and a triangle
What does congruent and simliar mean?
Congruent means when 2 shapes are exactly the same Similar means the shapes are exactly same but with different sides
What 2 elements have the similar properties to potassium?
any element in group !
