The correct answer would be the last option. 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. They are called cations. These elements are beryllium, magnesium, calcium, strontium, and radium.
Answer:
D) force,cause, displacement
Density=mass/volume
Mass = 0.0500g
Volume = 6.40mL
0.0500g/6.40mL = 0.0078g/mL
1. neutron
2. proton which is positive
3. electron which is negative
S. Properties can be anything from composition to color to ductility. Without knowing an object's properties, it is impossible to characterize it. For example, looking at some common properties of metals helps to differentiate them from non-metals or metalloids.
