Answer:Here u go!

Explanation:

The number of protons, neutrons, and electrons in an atom can be determined from a set of simple rules. The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons.

Hope this helps

Answer:

The atomic number equals the charge on the nucleus. It therefore also equals the number of protons in the nucleus and also equals numerically the number of electrons in the neutral atom. The atomic number has the symbol Z.

Isomers of hydrocarbons have the same _______formula but different ____formula.

Misha Larkins [42]

Answer:

Isomers of hydrocarbons have the <u>molecular</u> formula but <u>structural</u> formula.

Explanation:

Molecules with the same structural formula, but different molecular geometries (spatial arrangement) are called isomers. These differences in the arrangement of the various atoms confer certain differences in chemical properties to the resulting hydrocarbons, even though their chemical composition is the same. There are two types of isomers:

Structural isomers: Here, each atom are connected or bonded in different ways, hence structural isomers may contain different functional groups or pattern of bonding. structural isomers are further divided into: chain, position, and functional group isomers.

Stereoisomers: Here, the connections of the atoms are the same, but the difference is in their orientation in space

The atomic mass of chlorine is 17 give the electron configuration for a neutral atom of chlorine

Nana76 [90]

1s²2s²2p⁶3s²3p⁵

Explanation:
In writing the first two electrons will go in the 1s orbital.
Since 1s can only hold two electrons the next 2 electrons for chlorine go in the 2s orbital.
The next six electrons will go in the 2p orbital.
The p orbital can hold up to six electrons.
We'll pull six in the 2p orbital and then put the next two electrons in the 3s.
Since the 3s is now full we'll move to the 3p where we'll place the remaining five electrons.

Hope this helped ;)
