Explanation:

The 5 things that the periodic table includes are;

1. Name of the element

2. The symbol of the element

3. Atomic number of the element

4. Relative atomic mass

5. Electron configuration

Answer:

6 F atoms at 6 corners

Explanation:

The shape of IF6 (-1) is trigonally distorted octahedron. The central iodine atom has 7 valence electrons. It gains one electron from negative charge. Out of 8 electrons, 6 are imvolved in formation of 6 I - F bonds and one lone pair of electrons is present. 6F atoms are present at 6corners of distorted octahedron. The lone pair of electrons distorts the octahedral shape due to electron repulsion.

Answer:

six noble gases

Here are five of the six noble gases: helium, neon, argon, kypton and xeon. They're all colourless and transparent. Krypton and xeon form compounds only with difficulty. Helium, neon and argon don't form compounds at all.

Answer:

There are in total 6  noble gases in the periodic table.

Namely,

1. Helium

2. Neon

3. Argon

4. Krypton

5. Xenon

6. Radon

Answer:

because the number of constitutional confirmation , and geometric isomers goes up with each carbon atom added there are many more possible configurations and connectivities possible with decane , a 10 carbon chain , than with butane, a 4 carbon chain

"The number of possible isomers go up with an increasing number of carbon atoms because as the number of carbon atoms increases the tendency to form branching with other carbon atom increases as well."

What is isomer?

Isomers are molecules or polyatomic ions that have the same molecular formulas that is, the identical number of atoms of each element but different atomic configurations in space. Isomerism refers to the existence or potential of isomers. Isomers don't have to have the same chemical or physical properties.

Answer:

4.54 * 10^-14 m

Explanation:

From Heisenberg's uncertainty principle, we can write;

Δp.Δx ≥ h/4π

Given that;

Δp =Δmv

So;

Δmv.Δx ≥h/4π

Δmv =2/100(3.5×10^7 m/s * 1.66 * 10^-27)

Δmv =1.162 * 10^-21 Kgms-1

Δx ≥6.63 * 10^-34 /4 * 3.142 * 1.162 * 10^-21

Δx ≥4.54 * 10^-14 m

Answer:The relationship which is between bacteria and ungulates with the intestine is or good example of mutualism. Mutualism plays an important role in ecology. We can say that if we measure the exact fitness what we get as a benefit is a mutualistic relationship.example of a mutualistic relationship is that of the oxpecker (a kind of bird) and the rhinoceros or zebra. Oxpeckers land on rhinos or zebras and eat ticks and other parasites that live on their skin. The oxpeckers get food and the beasts get pest control.

Answer; 2.531 moles

Explanation:

(diagram below)

1. has two electron shells, so draw two rings around the nucleus

2. has 4 electrons, and since the first shell always has two the second shell would have 2 as well (to add up to four). this makes sense, because the description says that Be has 2 valence electrons

3. Draw 4 protons inside the grey circle (the nucleus)

4. Draw 5 neutrons inside the grey circle too (the nucleus)

they don't have to be in any particular order, hope this helps!

Beryllium (Be) atom has 5 neutrons, 4 electrons and 4 protons. It has two electron shells as it is in the second period of the periodic table.

Only two electrons can fit in the first shell, which is the innermost shell. Beryllium has two electrons in its initial shell. There are additionally 2 electrons in the second shell, which is the outermost shell for beryllium. Valence electrons are the moniker for these outermost electrons.

The electron configuration of beryllium is 1s² 2s², where the superscript refers to the number of electrons in each orbital and shell. The two electrons in the 1s orbital of the first shell are denoted by the symbol 1s², while the two electrons in the 2s orbital are denoted by the symbol 2s².

Precipitation.

Humidity is the amount of water vapour in the air. This is produced by the evaporation

of water from oceans, lakes, rivers, wetlands and plants.

When water evapour in the air cools, it condenses. In other words, it becomes liquid and

forms little drops. These droplets form clouds.

When the droplets are small, they remain suspended in the atmosphere. But they often

become colder and their size and weight increases When they become too heavy to

remain suspended in the air, they fall to the Earth’s surface. We call this precipitation,

which may be rain, snow or hail.

Factors affecting precipitation.

Different areas of the Earth’s surface receive different amounts of precipitation.

 Latitude: it rain more in the areas near the equator than in the temperature

zones and polar regions. The temperature is higher near the Equator so there is

more evaporation.

 Altitude: it rains more in high areas than in low areas.

 Level of humidity: it rains more on the coast than inland. Seas are a source of

humidity.

Precipitation is measured in millimeters (mm) per square matre.

HYBRIDIZATION:

Answer:

Hybridization is the idea that atomic orbitals fuse to form newly hybridized orbitals, which in turn, influences molecular geometry and bonding properties. Hybridization is also an expansion of the valence bond theory

The use of fog and mist at this time can reduce the air temperature and increase the humidity within the plant canopy without saturating the plant medium.
