Periodic Table

Zinc Oxide.

Additional answer

Except that you won't find ZnO in the periodic table because that table is a table of only the elements and ZnO is a compound, not an element.

It doesn't technically stand for anything in the periodic table. Zn is the chemical symbol for Zinc, a transition metal, and O is the chemical symbol for Oxygen, a non-metal. The chemical formula ZnO is Zinc Oxide, a white powdery compound.

Argon is one of the inert or "noble" gasses which do not participate in any chemical reactions. Others include helium, neon, xenon, krypton, and radon.

Aside from radon, which is radioactive, all the other inert gasses behave pretty much the same way. They do not combine chemically with any other elements. (There are a couple of cases of radon "combining" in a complex molecule at very low temperatures, but this is more a case of the radon atom being trapped as the rest of the compound freezes around it.)

No, nonmetals do not always have higher electron affinity than metals. Electron affinity depends on the specific element and its position in the periodic table. Some metals can have higher electron affinities than certain nonmetals.

Xenon as it is a noble gas. Noble gases are inert and do not react with anything.

Selenium is a solid

Chlorine is a green coloured highly reactive poisonous gas.

Carbon is a non-metallic solid.

Mendeleev organized the elements in his periodic table based on increasing atomic mass. He noticed that certain properties repeated periodically when the elements were arranged in this way.

For main group elements the column number is a concrete indication of then number of valence electrons (and therefore oxidation number). And since it tells you the number of valence electrons you can get a substantially reliable idea of how reactive the element is

When heated, sodium chloride (table salt) remains as solid salt. When heated to very high temperatures, around 801°C (1474°F), it will melt into a liquid form. Only when it reaches the extreme temperature of 1465°C (2669°F) does it decompose into its constituent elements, sodium and chlorine.

The position of an element in a horizontal row, or period, in the periodic table tells you the number of electron energy levels that element's atoms have. As you move from left to right across a period, the number of electrons in the outer energy level of the atoms increases by one.

Electronegativity decreases as you go down a group in the periodic table. This is because as you move down a group, the atomic radius increases, leading to a decrease in the attraction between the nucleus and the outer electrons, resulting in lower electronegativity values.

There are more metals than nonmetals on the periodic table. There are 18 nonmetals, compared to 117 known elements.

The periodic table was developed by Dmitri Mendeleev in 1869. Mendeleev organized the elements by their atomic mass and observed that elements with similar properties occurred at regular intervals. This arrangement formed the basis for the modern periodic table.

The horizontal rows are referred as periods. There are 7 periods in periodic table.

Lead is situated in group 14 of the periodic table, which is known as the Carbon group. It is a heavy metal with the atomic number 82 and is located below tin and above bismuth. Lead exhibits properties of both metals and nonmetals and has been used in various applications such as batteries, bullets, and plumbing.

that's manganese.

Metals are typically found on the left-hand side of the periodic table. This includes elements such as lithium, sodium, and iron. Nonmetals are generally found on the right-hand side.

in period 1, 2 and 3 the number reduces. In period 1 from 2 to 1. In period 2 and 3 it reduces from 8 -1. In the other periods the d and f subshells are involved in the transtion metals and lanthanides and actinides. As you go from group 18 to group 13 there is a steady reduction beyond that the situation is a bit more complex. Check the electron configurations of each elemnt if you need to go to this depth.

A periodic table will be extremely helpful in this case. If you would've taken the smallest of glances, you could see that copper's (Cu) atomic number is 29.

A periodic table is in the link below should you decide to use it.

yes, alkali metals are placed on left side. eg-group-1 and 2 elements

The first ionization energy generally increases across a period from left to right on the periodic table. This is due to the increased nuclear charge, leading to stronger attraction between the electrons and the nucleus, making it more difficult to remove an electron.

In the alkali metals column (Group 1), atomic radius increases down the group and reactivity increases. There are more shells preventing the attraction between the positive nucleus and negatively charged outer electron. (All Group 1 elements have 1 electron in their outer shell). Also, because they contain more shells down the group, the distance between the nucleus and electrons is increased. Therefore the electrostatic force is lessened between them. Both of these allow the outer electron to be lost easier to other elements, thus increasing reactivity.

No, penicillin is not an element on the periodic table. Penicillin is a type of antibiotic drug derived from molds, specifically Penicillium fungi. It is a medication used to treat bacterial infections.

Atomic size decreases from left to right in a period hence ioniztion energy increases from left to right.But atomic size increases from top to bottom in a group hence ionization energy decreases from top to bottom.

Groups are vertical columns on the periodic table consisting of elements with the same number of valence electrons. Periods are horizontal rows with elements sharing a highest unexcited electron energy level.

There are 10 different groups of 3 people that can be formed from a group of 5 people. This can be calculated using the combination formula, which is nCr = n! / r!(n-r)!, where n is the total number of people and r is the number of people in each group.
