Hydrocarbon:

A hydrocarbon is class of organic chemicals made up of only the elements carbon (C) and hydrogen (H).The carbon atoms join together to form the framework of the compound, and the hydrogen atoms attach to them in many different configurations.

Now consider the Lewis dot structure of CH₄ i.e. the simplest hydrocarbon attached below

The electron dot structures are used to show the bond formation among the elements of a covalent chemical compound. Similarly, the CH₄ is also a covalent compound. There are 4 valence electrons of the central carbon atom and each of the four hydrogen atoms have 1 valence electrons.

Answer from: girlysimbelieve

4 hydrogen atoms are attached with the carbon atom in the molecule.

Explanation:

Hydrocarbon molecule is a type of molecule which is composed of hydrogen and carbon atoms. Carbon atom belongs to group 4 in the periodic table which means it has four electrons in its outermost shell or orbit, so for attaining octet rule, carbon atom makes 4 covalent bonds with 4 hydrogen atoms and 4 electrons of hydrogen atom is used by the carbon atom and becomes a stable molecule.

Answer from: Quest

$\frac{239}{94}pu+\frac{1}{0}n ====> \frac{y}{z}x+\frac{134}{54}xe+3\frac{1}{0}$

the catch is that the top numbers are atomic masses the bottom numbers are the numbers of protons and electrons in an uncharged atom. they are the number of that atoms as you would find them on the periodic table. further, the numbers on the left are used to determine the missing numbers on the right

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137 subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54 subtract 54 from both sides.

40 = z

answer

$\frac{103}{40}x=\frac{103}{40}zr$
