The atomic number is the total numbers of protons in an element
<span><span> i think the answer is that >>>>>Ernest Rutherford was born in rural Spring Grove, on the South Island of New Zealand on August 30, 1871. He was the fourth of 12 children, and the second son. His father, James, had little education and struggled to support the large family on a flax-miller’s income. Ernest’s mother, Martha, worked as a schoolteacher. She believed that knowledge was power, and placed a strong emphasis on her children’s education.As a child, Ernest, whose family called him “Ern,” spent most of his time after school milking cows and helping with other chores on the family farm. Weekends were spent swimming in the creek with his brothers. Since money was tight, Rutherford found inventive ways of overcoming his family’s financial challenges, including birds-nesting to earn funds for his kite-flying supplies. “We haven’t the money, so we’ve got to think,” was Rutherford’s motto at the time.<span><span /></span>

Liquid - takes the shape of the container and maintains volume
Solid- maintain shape
<span>For the answer to the question above,
If 3g of element combines with 8g of D to form CD it means
1 mole of C = 3g
1 mole of D = 8g
hence it forms CD.
So to form CD2 you need 16g of element D
I hope my answer helped you</span>
Simple molecular substances consist of molecules in which the atoms are joined by strong covalent bonds. However, the molecules are held together by weak forces so these substances have low melting and boiling points.
I hope this helps.=^P
