Answer:
it readily gains another electron. the outer electron shell is closer to the nucleus, than iodine for example, which makes it less shielded (greater attraction for another electron = violent reaction to get it)
Explanation:
Answer:
No, these sample could no be same
Explanation:
Percentage of copper in both sample are different means both are taken from different sample because if we says both are from same sample then its violates the law of definite proportion
according to this law a given compound always contains same proportion of element by mass and it does not depend on the source
eg: water from sea and drainage both have same composition means same amount of oxygen and hydrogen by mass is present
Hence given samples are not same
Answer:
Rutherford predicted that an atom has a dense core called a <u>nucleus</u>.
Explanation:
Ernest Rutherford was a physicist who is known as the father of nuclear physics. He suggested an atomic model known as the Rutherford model. According to him, the atom consists of a tiny, dense, positively charged core called a nucleus and negatively charged particles called electrons that circulate around it The nucleus consists of positively charged particles called protons and neutral particles called neutrons.
