What kind of bond would form between an iron and an oxygen atom: ionic, covalent, or metallic? What kind of bond would form between two silver atoms: ionic, covalent, or metallic? What happens to the valence electrons in this bond? How do ionization energy and electronegativity help explain why this occurs? 3) What kind of bond would form between two chlorine atoms: ionic, covalent, or metallic? What happens to the valence electrons in this bond? How do ionization energy and electronegativity help explain why this occurs?

Answers

Answer:

See explanation

Explanation:

Since iron is a metal and oxygen is a non metal, a bond is formed between the two when electrons are transferred from iron to oxygen. Hence the bond is ionic.

Two silver atoms are held together by metallic bonds. Metallic bond are bond forces that exist between metal atoms in a crystal lattice. The valence electrons in this bond form a cloud. Metals have low ionization energy and low electronegativity hence they loose electrons easily. This accounts for the nature of the metallic bond.

The bond formed between two chlorine atoms is a covalent bond. The valence electrons in this bond are localized between the two chlorine atoms. Chlorine is a nonmetal hence it has a high ionization energy and high electronegativity. Hence it forms covalent bonds in which electrons are shared between bonding atoms.

Which has a higher frequency: microwaves or blue light? How do you know?​

Answers

Answer:

Microwaves

Explanation:

Microwaves have more energy than blue light

Among microwaves or blue light, blue light has a higher frequency. This is because blue light belongs to the visible region has a short wavelength and produces a higher amount of energy.

What is the relationship between frequency and wavelength?

The frequency of any wave is inversely related to the wavelength. This means that when the frequency of the wave increases, the wavelength decreases. While the relationship between frequency is directly related to the energy.

According to the context of this question, gamma rays have the highest frequency and shorter wavelength, while radiowaves have a shorter frequency and the highest wavelength.

Therefore, blue light has a higher frequency. This is because blue light belongs to the visible region has a short wavelength and produces a higher amount of energy.

After the students classified themselves as an athlete or a nonathlete, their resting pulses were determined. Then all the students performed the same exercise for four minutes and their heart rates were determined by recording the pulse rate in beats per minute. The students continued to measure their pulse rates for an additional four minutes. The average heart rate per minute for each group was determined.

What do the colors on the periodic table show?

B. the metallic properties of the element
C. the types of compounds the element can make
D. whether the element is a solid, a liquid, or a gas at room temperature

Answers

Answer:

Periodic tables can use color to identify other element characteristics. For example, an electronegativity periodic table color codes the elements based on how electronegative they are. The valence periodic table uses color to identify the most common valence state for each element.Oct 2, 2019

pls like and rate us .

The color given to a the elements in periodic table is to characteristics of the elements mainly to identify whether they are solid, gas or liquid. Thus option D is correct.

What is periodic table?

A periodic table contains all the discovered elements which are classified into different groups and periods. Groups are vertical columns of elements with similar properties and same number of valence electrons.

Periods are horizontal rows from left to right with an increase in atomic number. There are 18 groups and 7 periods in periodic table. Each group has given each color and some elements showing exceptional characteristics such as hydrogen and helium have separate colors.

All the first group elements called alkali metals have one color and the second groups elements with another color, All the d-block elements are given the same colour and metals in p-block elements have the same color.

Similarly, all the metalloids have one color and all other gases have the same colour in which inert gas group and halogen group have seperate colours.

Hence, the color in periodic table helps to identify the element's nature like its state also. Thus option D is correct.

How much radium-226 will remain from a 20 gram sample after 4800 years?

Answers

Answer:

2.5 g mass of Ra-226 will remain after 4800 years.

Explanation:

Given data:

Mass of Ra-226 = 20 g

Sample remain after 4800 years = ?

Solution:

Half life of Ra-226 = 1600 years

Number of half lives passed = T elapsed / half life

Number of half lives passed = 4800 year / 1600 year

Number of half lives passed = 3

At time zero = 20 g

At first half life = 20 g/2 = 10 g

At 2nd half life = 10 g/2 = 5 g

At 3rd half life = 5 g/2 = 2.5 g

Thus, 2.5 g mass of Ra-226 will remain after 4800 years.
