Since cells are hard to see the microscope helped them see. scientist were able to actually see cells in tissues placed under the microscope.
Answer:the strength of a bond depends on the amount of overlap between the atoms.
Explanation:the greater the overlap the greater the strength of the bond.
Answer:
E²⁺
Explanation:
The group two contain alkaline earth metals.
There are six elements in group 2A.
Beryllium, Magnesium, calcium, strontium, barium and radium.
All members have two valance electrons.
They lose two valance electrons to complete the octet.
When they lose the two valance electrons they form cation X²⁺.
They react with halogens and form salt such as
MgCl₂, CaCl₂ etc.
Mg²⁺ Cl²⁻₂
The oxidation state of halogens are -1, while the elements of group two A shows +2 that's why two atoms of halogen are combine with one atom of alkaline earth metals and make the compound overall neutral.
All the alkaline earth metals have similar properties.
CaBr conducts electricity in the molten state but does not conduct as a solid. ionic dissolution equation.
Its obviously D like what are you stupid lol jk don’t take it to heart kid
