Answer:
It looks like a solid because they are densely packed kind of like an ice cube
Explanation:
The state of matter shown in this figure is solid state, because the particles are arranged densely in the form of cube.
What is solid state ?The state of matter known as a solid has a definite form, mass, and volume. Changing the temperature causes extremely little variations in volume to be seen. For instance, sand, wood, copper, ice, etc., cannot be crushed.
One of the three fundamental states of matter, along with liquid and gas. Since atoms' energy drops when they adopt a comparatively organized, three-dimensional structure, solids can emerge from liquids or gases.
Because solids have specific mass, volume, and form, their component particles are arranged compactly. Between molecules, there is little intermolecular space. As a result, there is a strong force between the constituent particles (atoms, molecules, or ions).
Thus, option A is correct.

describe the relationship between the mass volume and density of material
Answers
Answer: For a given mass and volume, how much physical space a material takes up, of an object or substance, the density remains constant at a given temperature and pressure. The equation for this relationship is ρ = m / V in which ρ (rho) is density, m is mass and V is volume, making the density unit kg/m3.

The equation is showing how it is formed, so the answer is on the other side of the equal sign.
There are two types of chemical compound one is covalent compound and other is ionic compound, covalent compound formed by sharing of electron and ionic compound formed by complete transfer of electron. Therefore, diagram C shows the final compound.
What is chemical Compound?Chemical Compound is a combination of molecule, Molecule forms by combination of element and element forms by combination of atoms in fixed proportion.
An ionic compound is a metal and nonmetal combined compound. Ionic compound are very hard. They have high melting and boiling point because of strong ion bond.

Elements are the smallest unit of the atom and cannot be divided. An element having 5 electrons, protons, and neutrons is a boron.
What are subatomic particles?Subatomic particles are the constituents of atoms that have mass and charge. They are the components that make the element unique and give the atomic number and the mass.
The electron is a negatively charged particle and protons are positive particles that along with neutral neutron give the atomic mass. An element with 5 sub atomic particles is called a boron.

Which two parts are needed to make a neutral atom of nitrogen A. Electron clouds with a total of 14 electrons B. Electron cloud is a total of seven electrons C. A nucleus with seven protons and seven neutrons D. A nucleus with three protons and four neutrons
Answers
Answer:
B. Electron cloud is a total of seven electrons
C. A nucleus with seven protons and seven neutrons
Explanation:
An atom is consist of three subatomic particles: electron, proton, and neutron. Proton are positively charged particles and neutron have neutral charge, they both are present inside the nucleus in the center of the atom whereas electrons are negatively charged and surround the nucleus in a definite orbit.
Nitrogen is an element with 7 electrons in its outer orbit. As electrons are negatively charged so nitrogen atom will require 7 protons inside the nucleus to form a neutral atom of nitrogen. So, A neutral atom of nitrogen will consist of 7 electrons and 7 protons.
As, neutron has neutral charge so it will not affect the composition of neutral atom of nitrogen.
Hence, the correct options are:
"B. Electron cloud is a total of seven electrons
C. A nucleus with seven protons and seven neutrons ".

Oshiny
O malleable.

Owing to the electronic configuration of metals ,metallic bonding exists in metals because of which when light is pointed at them they become shiny.
What is electronic configuration?Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.
Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.
Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.
