18 electrons. With a -2 charge, that means it gains two electrons.
Answer:
ion
Explanation:
An atom that has lost or gained an electron no longer has a neutral charge. We call this negatively or positively charged atom a(n) ________.
ion
Answer:
The correct answer is
C. 6 Protons
Explanation:
Carbon is a nonmetallic element that is available in both organic and inorganic compounds.
Carbon belongs to group 14 elements in the periodic table,carbon is a chemical element with the symbol C and atomic number 6, it can form long chains with its own atoms, a feature called catenation.
Two allotropes of carbon available are diamonds and graphites, which have different crystalline structures
The physical properties of carbon vary widely with the allotropic form.
examples are.
- Graphite, diamonds and coal are all nearly pure forms of carbon
- Diamond is highly transparent. Graphite is opaque and black
- Diamond is one of the hardest substances known to man. Graphite is soft and often used as the "lead" in lead pencils
- Diamond has a very low electrical conductivity. Graphite is a very good conductor
- Very brittle, and cannot be rolled into wires or pounded into sheets
Answer:
Answer is 2nd
Explanation:
some energy is transformed into mass
Answer: The name of the
is Iodine tetrabromide and it is a covalent compound.
Explanation:
Inter-halogen compounds are compounds which composed of two different halogen atoms. For example ;
etc.
The naming is done by first writing the central atom symbol's name followed by the prefix corresponding to the number of atoms of another halogen atom like: Mono for 1, di ,for 2 tri for 3, tetra for 4 , penta for 5 etc. After this name of the another halogen is written with suffix 'ide' in the end.
The name of the
is Iodine tetra bromide.
In halogen compounds, the difference in electronegativities is not so large due to which they form covalent compounds by the means of sharing the electrons. Hence the Iodine tetrabromide covalent compound.
