Chemistry
1 answer:
kakasveta [241]3 years ago
6 0

Answer:

a. similar properties

Explanation:

In a given column of the periodic table, the elements have similar properties.

A column on the periodic table is known as a group or family. The group is a vertical arrangement of elements  on the periodic table.

Elements in the same group have the same number of valence electrons after their group number.

For example, all the elements in group 1 have one valence electron. Those in group 2 have 2 valence electrons.

The valence electrons of an atom determines its chemical properties. So, all elements in the same group have the same chemical properties.

A 10-ft moving truck has a volume capacity of 402 cubic feet, which is equivalent to 1.138 x 10⁷ milliliters. What mass of silve
steposvetlana [31]

Answer:

The mass of silver is 1.19\times 10^{14}\ Mg

Explanation:

Given that,

The volume of the truck is 402 cubic feet or 1.138 x 10⁷ mm.

The density of silver is 10.49 g/mL.

We need to find the mass of silver that will fit in this moving truck. Density equals mass divided by volume. So,

d=\dfrac{m}{V}\\\\\text{where m is mass}\\\\m=d\times V\\\\m=10.49\ g/mL\times 1.138 \times 10^7\ mL\\\\m=119376200\ g

1 gram = 10⁻⁶ Megagram

119376200=1.19\times 10^{14}\ Mg

Hence, the mass of silver is 1.19\times 10^{14}\ Mg

If an element has 35 electrons and its mass number is 37, what is its atomic number and how many neutrons does it have?. Multi L
Lynna [10]

Answer:

Atomic Number: 35

Number of Neutrons: 2

Explanation:

The number of protons and electrons are the same, so given that this element has 35 electrons, it also has 35 protons.

Atomic number is the number of protons, so it is 35.

Mass number is the number of protons + neutrons, so take the mass number of 37 and subtract the 35 protons to get 2 neutrons.

3. Other than being gases, what is special about the Noble Gases? ​
nydimaria [60]

Answer:

All the noble gases have the full number of electrons in each layer.

Explanation:

For example, neon is a noble gas. The first layer of electrons is full since it contains the max amount of electrons which is 2. The next layer is also full, since it contains 8 electrons which is the max amount it can hold.

I hope this helped and please mark me as brainliest!
