He discovered this by firing Alpha particles at a gold foil and most alpha particles went through the foil and a few were deflected. The area where the alpha particles were deflected were assumed where the small dense positively charged nucleus was located. And electrons were scattered in the empty space out side the small nucleus.

Answer:
It is not a legitimate chemical name because the methyl group on carbon 1 increases the length of the carbon chain to seven carbon atoms thus making the parent compound heptane
Explanation:
Chemical compounds are named according to rules in the IUPAC nomenclature.
In naming organic compounds, parts of rules is to find out the parent or root compound. This is determined by finding out the longest carbon chain and then checking if it contains single or multiple bonds. (that is if it is an alkane- with single bonds, alkene-with double bonds or an alkyne- with triple bonds)
From the question the parent or root name is an alkane containing 6 (Hex-) carbon atoms, while the methyl group is substituent
(CH₃)-CH₂-CH₂-CH₂-CH₂-CH-CH₃
However the alkyl substituent on carbon 1 increases the the length of the carbon chain to 7 (Hept-) instead of 6. Hence the correct IUPAC nomenclature is heptane and not 1-methylhexane.
The answer to this question is atomic number
Answer:
1) incorrect
2) incorrect
3) correct
4) correct
5) correct
6) incorrect
Explanation:
The correct electronic configuration of chromium is; [Ar] 3d⁵ 4s¹
The correct electronic configuration for Zr is; [Kr] 4d² 5s²
The correct electronic configuration of Cu^+ is; [Ar] 3d¹⁰
The electronic configuration of an atom refers to the arrangement of electrons in the atoms of such element.
The appropriate number of electrons and its properly written electronic configuration is clearly shown in this answer.
